Overview

To mount a Finding Aids Collection, you will need to complete the following steps:

1. Prepare your data and set up a directory structure: see Preparing Data and Directories
2. Validate and normalize your data: xref
3. Build the Index: xref
4. Mount the collection online: xref

Overview of Data Preparation and Indexing Steps

Data Preparation

1. Validate the files individually against the EAD 2002 DTD
   make validateeach
   
2. Concatenate the files into one larger XML file
   make prepdocs
   
3. Validate the concatenated file against the dlxsead2002 DTD:
   make validate
   
4. Normalize the concatenated file.
   make norm
   
5. Validate the normalized concatenated file against the dlxsead2002 DTD
   make validate
   

The end result of these steps is a file containing the concatenated EADs wrapped in a <COLL> element which validates against the dlxsead2002 and is ready for indexing:

<COLL>
<ead><eadheader><eadid>1</eadid>...</eadheader>... content</ead>
<ead><eadheader><eadid>2</eadid>...</eadheader>... content</ead>
<ead><eadheader><eadid>3</eadid>...</eadheader>... content</ead>
</COLL>

WARNING! If are extra characters or some other problem with the part of the program that strips out the xml declaration and the docytype declearation the file will end up like:

<COLL>
baddata<ead><eadheader><eadid>1</eadid>...</eadheader>... content</ead>
baddata<ead><eadheader><eadid>2</eadid>...</eadheader>... content</ead>
baddata<ead><eadheader><eadid>3</eadid>...</eadheader>... content</ead>
</COLL>

In this case you will get "character data not allowed" or similar errors during the make validate step. You can troubleshoot by looking at the concatenated file and/or checking your original EADs.

Indexing

1. make singledd indexes words for texts that have been concatenated into on large file for a collection.
2. make xml indexes the XML structure by reading the DTD. Validates as it indexes.
3. make post builds and indexes fabricated regions based on the XPAT queries stored in the workshopfa.extra.srch file.

Working with the EAD

EAD 2002 DTD Overview

These instructions assume that you have already encoded your finding aids files in the XML-based EAD 2002 DTD. If you have finding aids encoded using the older EAD 1.0 standard or are using the SGML version of EAD2002, you will need to convert your files to the XML version of EAD2002. When converting from SGML to XML a number of character set issues may arise. See Data Conversion and Preparation: Unicode,XML, and Normalization

Resources for converting from EAD 1.0 to EAD2002 and/or from SGML EAD to XML EAD are available from:

• The Society of American Archivists EAD Tools page:http://www.archivists.org/saagroups/ead/tools.html
• Library of Congress EAD conversion toolshttp://lcweb2.loc.gov/music/eadmusic/eadconv12/ead2002_r.html

Other good sources of information about EAD encoding practices and practical issues involved with EADs are:

• Library of Congress EAD page http://www.loc.gov/ead/ (This is the home of the EAD standard
• EAD2002 tag library http://www.loc.gov/ead/tglib/index.html
• The Society of American Archivists EAD Help page: http://www.archivists.org/saagroups/ead/
• Various EAD Best Practice Guidelines listed on the Society of American Archivists EAD essentials page: http://www.archivists.org/saagroups/ead/essentials.html (the links to BPGs are at the bottom of the page)
• The EAD listserv http://listserv.loc.gov/listarch/ead.html

Practical EAD Encoding Issues

The EAD standard was designed as a loose standard in order to accommodate the large variety in local practices for paper finding aids and make it easy for archives to convert from paper to electronic form. As a result, conformance with the EAD standard still allows a great deal of variety in encoding practices.

The DLXS software is primarily designed as a system for mounting University of Michigan collections. In the case of finding aids, the software has been designed to accommodate the encoding practices of the Bentley Historical Library. The more similar your data and setup is to the Bentley’s, the easier is will be to integrate your finding aids collection with DLXS. If your practices differ significantly from the Bentley’s, you will probably need to do some preprocessing of your files and/or make changes to DLXS.

More information on the Bentley's encoding practices and workflow:

• Overview of Bentley's workflow process for Finding Aids http://bentley.umich.edu/EAD/eadproj.htm
• Description of Bentley Finding Aids and their presentation on the web http://bentley.umich.edu/EAD/findaids.htm
• Bentley MS Word EAD templates and macros http://bentley.umich.edu/EAD/bhlfiles.htm
• Description of EAD tags used in Bentley EADs http://bentley.umich.edu/EAD/bhltags.htm

Types of changes to accomodate differing encoding practices and/or interface changes

• Custom preprocessing
• Add dummy EAD to data
• Modify prep scripts (Makefile, preparedocs.pl, validateeach.csh)
• Modify *inp files (DOCTYPE declarations and entities)
• Modify fabricated regions (*.extra.srch)
• Modify CollMgr entries
• Modify findaidclass.cfg (change table of contents sections)
• Subclass FindaidClass.pm
• Modify XSL
• Modify XML templates
• Modify CSS

Specific Encoding Issues

There are a number of encoding issues that may affect the data preparation, indexing, searching, and rendering of your finding aids. Some of them are:

• Preprocessing and Data Prep issues
  • Character Encoding issues
  • Attribute ids must be unique within the entire collection
  • If you use attribute ids and corresponding targets within your EADs preparedocs.pl may need to be modified.
  • <eadid> should be less than about 20 characters in length
  • UTF-8 Byte Order Marks (BOM) should be removed from EADs prior to concatenation
  • XML processing instructions should be removed from EADs prior to concatenation
  • Multiline DOCTYPE declarations are currently not properly handled by the data prep scripts
  • If your DOCTYPE declaration contains entities, you need to modify the appropriate *inp files accordingly
  • Out-of-the-box <dao> handling may need to be modified for your needs

• Fabricated region issues (some of these involve XSL as well)
  • If your <unititle> element precedes your <origination> element in the top level <did>, you will have to modify the maintitle fabricated region query in *.extra.srch See Troubleshooting:Title of Finding Aid does not show up
  • If you do not use a <frontmatter> element, you will have to create a fabricated region to provide an appropriate "Title Page" region based on the <eadheader> and you may also need to change the XSL and/or subclass FindaidClass to change the code that handles the Title Page region.

• Table of Contents and Focus Region issues
  • If you do not use a <frontmatter> element you may have to make the changes mentioned above to get the title page to show in the table of contents and when the user clicks on the "Title Page" link in the table of contents
  • If your encoding practices for <biohist> differ from the Bentley's, you may need to make changes in findaidclass.cfg or create a subclass of FindaidClass and override FindaidClass:: GetBioghistTocHead, and/or change the appropriate XSL files.
  • If you want <relatedmaterial> and/or <separatedmaterial> to show up in the table of contents (TOC) on the left hand side of the Finding Aids, you may have to modify findaidclass.cfg and make other modifications to the code. This also applies if there are other sections of the finding aid not listed in the out-of-the-box findaidclass.cfg %gSectHeadsHash.
  • See also Customizing Findaid Class: Working with the table of contents

• XSL issues
  • If you have encoded <unitdate>s as siblings of <unittitle>s, you may have to modify the appropriate XSL templates.
  • If you want the middleware to use the <head> element for labeling sections instead of the default hard-coded values in findaidclass.cfg, you may need to change fabricated regions and/or make changes to the XSL and/or possibly modify findaidclass.cfg or subclass FindaidClass.

Findaid Class Behaviors Overview

Preparing Data and Directories

Set Up Directories and Files for Data Preparation

You will need to set up a directory structure where you plan to store your EAD2002 XML source files, your object files (used by xpat for indexing), index files (including region index files)and other information such as data dictionaries, and files you use to prepare your data.

The convention used by DLXS is to use subdirectories named with the first letter of the collection id and the collection name:$DLXSROOT/xxx/{c}/{coll}/ where $DLXSROOT is the "tree" where you install all DLXS components, {c} is the first letter of the name of the collection you are indexing, and {coll} is the collection ID of the collection you are indexing. For example, if your collection ID is "bhlead" and your DLXSROOT is "/l1", you will place the Makefile in /l1/bin/b/bhlead/ , e.g., /l1/bin/b/bhlead/Makefile. See the DLPS Directory Conventions section and Workshop discussion of Directory Conventionsfor more information.

When deciding on your collection id consider that it needs to be unique across all classes to enable cross-collection searching. So you don't want both a text class collection with a collid of "my_coll" and a finding aid class collection with a collection id of "my_coll". You will also probably want to make your collection ids rather short and make sure they don't contain any special characters, since they will also be used for sub-directory names.

Note that the Makefile we provide along with most of the data preparation scripts supplied with DLXS assume this directory structure.

We recommend you use the following directory structure:

• Store specialized scripts for preparing and/or preprocessing your collection and its Makefile in $DLXSROOT/bin/{c}/{coll}/ where $DLXSROOT is the "tree" where you install all DLXS components, {c} is the first letter of the name of the collection you are indexing, and {coll} is the collection ID of the collection you are indexing. For example, if your collection ID is "bhlead" and your DLXSROOT is "/l1", you will place the Makefile in /l1/bin/b/bhlead/ , e.g., /l1/bin/b/bhlead/Makefile. See the DLPS Directory Conventions section for more information.
• Store your source finding aids in $DLXSROOT/prep/{c}/{coll}/data/.

• Store any DTDs, doctype, and files for preparing your data in $DLXSROOT/prep/{c}/{coll}/. Unlike the contents of other directories, everything in prep should be expendable when actually running the indexes.
• After running all the targets in the Makefile, the finalized, concatenated XML file for your finding aids collection will be created in $DLXSROOT/obj/{c}/{coll}/ , e.g., /l1/obj/b/bhlead/bhlead.xml.
• Store index, region, data dictionary, and init files in $DLXSROOT/idx/{c}/{coll}/ , e.g., /l1/idx/b/bhlead/bhlead.idx. These will be updated as the index related targets in the Makefile are run. See the XPAT documentation for more on these types of files.

Fixing paths

The installation script should have changed all instances of /l1/ to your $DLXSROOT and all bang prompts "#!/l/local/bin/perl" to your location of perl. However, you may wish to check the following scripts:

• $DLXSROOT/bin/f/findaid/output.dd.frag.pl
• $DLXSROOT/bin/f/findaid/inc.extra.dd.pl
• $DLXSROOT/bin/s/samplefa/preparedocs.pl

If you use the Makefile in $DLXSROOT/bin/s/samplefa you should check that the paths in the Makefile are correct for the locations of xpat, oxs, and osgmlnorm as installed on your system. These are the Make varibles that should be checked:

• XPATBINDIR
• OSX
• OSGMLNORM

Step by step instructions for setting up Directories for Data Preparation

You can use the scripts and files from the sample finding aids collection "samplefa" as a basis for creating a new collection. In the instructions that follow you would use /{c}/{coll} instead of /w/workshopfa where {c} is the first letter of your collection id and {coll} is your collection id. So for example if your collection id was mycoll instead of

cp $DLXSROOT/prep/s/samplefa/samplefa.extra.srch $DLXSROOT/prep/w/workshopfa/workshopfa.extra.srch

you would do

cp $DLXSROOT/prep/s/samplefa/samplefa.extra.srch $DLXSROOT/prep/m/mycoll/mycoll.extra.srch

This documentation will make use of the concept of the $DLXSROOT, which is the place at which your DLXS directory structure starts. We generally use /l1/.

To check your $DLXSROOT, type the following command at the command prompt:

echo $DLXSROOT

The prep directory under $DLXSROOT is the space for you to take your encoded finding aids and "package them up" for use with the DLXS middleware. Create your basic directory $DLXSROOT/prep/w/workshopfa and its data subdirectory with the following command:

mkdir -p $DLXSROOT/prep/w/workshopfa/data

Move into the prep directory with the following command:

cd $DLXSROOT/prep/w/workshopfa

This will be your staging area for all the things you will be doing to your EADs, and ultimately to your collection. At present, all it contains is the data subdirectory you created a moment ago. Unlike the contents of other collection-specific directories, everything in prep should be ultimately expendable in the production environment.

Copy the necessary files into your data directory with the following commands:

cp $DLXSROOT/prep/s/samplefa/data/*.xml $DLXSROOT/prep/w/workshopfa/data/.

We'll also need a few files to get us started working. They will need to be copied over as well, and also have paths adapted and collection identifiers changed. Follow these commands:

cp $DLXSROOT/prep/s/samplefa/validateeach.csh $DLXSROOT/prep/w/workshopfa/.
cp $DLXSROOT/prep/s/samplefa/samplefa.xml.inp $DLXSROOT/prep/w/workshopfa/workshopfa.xml.inp
cp $DLXSROOT/prep/s/samplefa/samplefa.text.inp $DLXSROOT/prep/w/workshopfa/workshopfa.text.inp
mkdir -p $DLXSROOT/obj/w/workshopfa
mkdir -p $DLXSROOT/bin/w/workshopfa
cp $DLXSROOT/bin/s/samplefa/preparedocs.pl $DLXSROOT/bin/w/workshopfa/.
cp $DLXSROOT/bin/s/samplefa/Makefile $DLXSROOT/bin/w/workshopfa/Makefile

Now you'll need to edit these files to ensure that the paths match your $DLXSROOT and that the collection name is workshopfa instead of samplefa.

STOP!! Make sure you edit the files before going to the next steps!!

Make sure you change these files:

• $DLXSROOT/prep/w/workshopfa/validateeach.csh
• $DLXSROOT/bin/w/workshopfa/Makefile (see below for details)

You can run this command to check to see if you forgot to change samplefa to workshopfa:

grep "samplefa" $DLXSROOT/bin/w/workshopfa/* $DLXSROOT/prep/w/workshopfa/* |grep -v "#"

With the ready-to-go ead2002 encoded finding aids files in the data directory, we are ready to begin the preparation process. This will include:

1. Validating the files individually against the EAD 2002 DTD
2. concatenating the files into one larger XML file
3. validating the concatenated file] against the dlxsead2002 DTD
4. "normalizing" the concatenated file.
5. validating the normalized concatenated file against the dlxsead2002 DTD

These steps are generally handled via the Makefile in $DLXSROOT/bin/s/samplefa which we have copied to $DLXSROOT/bin/w/workshopfa. Example Makefile.

Make sure you changed your copy of the Makefile to reflect

/w/workshopfa instead of /s/samplefa. You will want to change lines 2 and 3 accordingly

   1  
   2  NAMEPREFIX = samplefa
   3  FIRSTLETTERSUBDIR = s

Tip: Be sure not to add any space after the workshopfa or w. The Makefile ignores space immediately before and after the equals sign but treats all other space as part of the string. If you accidentally put a space after the FIRSTLETTERSUBDIR = s , you will get an error like "[validateeach] Error 127" If you look closely at the first line of what the Makefile reported to standard output (see below) you will see that instead of running the command:

/l1/workshop/tburtonw/dlxs/prep/w/workshopfa/validateeach.csh

which just calls the validateeach c-shell script

it tried to run a directory name: "/l1/workshop/tburtonw/dlxs/prep/w" with the argument "/workshopfa/validateeach.csh" which does not make sense

 % make validateeach
/l1/workshop/tburtonw/dlxs/prep/w /workshopfa/validateeach.csh
make: execvp: /l1/workshop/tburtonw/dlxs/prep/w: Permission denied
make: [validateeach] Error 127 (ignored)

Further note on editing the Makefile: If you modify or write your own Make targets, you need to make sure that a real "tab" starts each command line rather than spaces. The easiest way to check for these kinds of errors is to use "cat -vet Makefile" to show all spaces, tabs and newlines

You should make sure you thate $DLXSROOT, and the locations of the various binaries to have been changed to match your installation.

• Change $DLXSROOT /l1/ to your $DLXSROOT on every line that uses it
• Change XPATBINDIR = /l/local/bin/ to the location of the xpat binary in your installation
• Change the location of the osx binary from

OSX = /l/local/bin/osx
to the location in your installation

• Change the location of the osgmlnorm binary from

OSGMLNORM = /l/local/bin/osgmlnorm
to the location in your installation

Tip: oxs and osgmlnorm are installed as part of the OpenSP package. If you are using linux, make sure that the OpenSP package for your version of linux is installed and make sure the paths above are changed to match your installation. If you are using Solaris you will have to install (and possibly compile) OpenSP. You may also need to make sure the $LD_LIBRARY_PATH environment variable is set so that the OpenSP programs can find the required libraries. For troubleshooting such problems the unix ldd utility is invaluble. [../troubleshooting/tools.html Information on OpenSP]

Move this to correct place in doc! If you have entity references in your EAD DOCTYPE declaration you will need to edit xxxx.inp Rewrite this to deal with the doctype declaration/entityref issues. XMLDOCTYPE = $(PREPDIR)$(NAMEPREFIX).xml.inp xxx.samplefa.xml.inp xxx.samplefa.text.inp (need to rename this!)

Set Up Directories and Files for XPAT Indexing

Please substitute /{c}/{coll} where {c} is the first letter of your collection id 
and {coll}is your collection id  for any instance of /w/workshopfa 
and substitute {coll} wherever you see "workshopfa" in the following instructions.

First, we need to create the rest of the directories in the workshopfa environment with the following commands:

mkdir -p $DLXSROOT/idx/w/workshopfa

The bin directory we created when we prepared directories for data preparation holds any scripts or tools used for the collection specifically; obj ( created earlier) holds the "object" or XML file for the collection, and idx holds the XPAT indexes. Now we need to finish populating the directories.

 cp $DLXSROOT/prep/s/samplefa/samplefa.blank.dd  DLXSROOT/prep/w/workshopfa/workshopfa.blank.dd
 cp $DLXSROOT/prep/s/samplefa/samplefa.extra.srch $DLXSROOT/prep/w/workshopfa/workshopfa.extra.srch

Each of these files need to be edited to reflect the new collection name and the paths to your particular directories. Failure to change even one file can result in puzzling errors, because the scripts are working, just not necessarily in the directories you are looking at.

grep -l "samplefa" $DLXSROOT/prep/w/workshopfa/*

will check for any leftover unchanged instances of the string /samplefa. You also need to check that "/l1/" has been replacedby whatever $DLXSROOT is on your server. If you don't have an /l1 directory on your server (which is very likely if you are not here using a DLPS machine) you can check with:

grep -l "l1" $DLXSROOT/prep/w/workshopfa/*

Data Preparation

Preprocessing

Validating and Normalizing Your Data

Step 1: Validating the files individually against the EAD 2002 DTD

cd $DLXSROOT/bin/w/workshopfa
make validateeach

The Makefile runs the following command:

% $DLXSROOT/prep/w/workshopfa/validateeach.csh

What's happening: The makefile is running the c-shell script validateeach.sh in the prep directory. The script creates a temporary file without the public DOCTYPE declaration, runs onsgmls on each of the resulting XML files in the data subdirectory to make sure they conform with the EAD 2002 DTD. If validation errors occur, error files will be in the data subdirectory with the same name as the finding aids file but with an extension of .err. If there are validation errors, fix the problems in the source XML files and re-run.

Check the error files by running the following commands

 ls -l $DLXSROOT/prep/w/workshopfa/data/*err

if there are any *err files, you can look at them with the following command: 

 less  $DLXSROOT/prep/w/workshopfa/data/*err

Common error messages and solutions:

onsgmls: Command not found

path to your installation of the onsgmls binary incorrect in $DLXSROOT/prep/s/samplefa/validateeach.csh

onsgmls:/l1/dev/tburtonw/misc/sgml/xml.dcl:1:W: SGML declaration was not implied

This is a warning (note the :W:) not an error and can be ignored. This warning can be silenced by changing line 6 of $DLXSROOT/prep/s/samplefa/validateeach.csh (or your customized version)

from:

onsgmls -s -f $file.err $DLXSROOT/misc/sgml/xml.dcl $DLXSROOT/prep/s/samplefa/samplefa.text.inp $file.tmp

to:

onsgmls -wxml -w no-explicit-sgml-decl -s -f $file.err $DLXSROOT/misc/sgml/xml.dcl $DLXSROOT/prep/s/samplefa/samplefa.text.inp $file.tmp

entityref errors such as "general entity 'foobar' not defined"

If you use entityrefs in your EADs, you may see errors relating to problems resolving entities. Example entityref errors. The solution is to add the entityref declarations to the doctype declaration in these two files:

$DLXSROOT/prep/s/samplefa/samplefa.text.inp

This is the doctype declaration used by the validateeach.csh script that points to the EAD2002 DTD.

$DLXSROOT/prep/s/samplefa/samplefa.xml.inp

This is the doctype declaration that points to the dlxs2002 dtd. The dlxs2002 dtd is used by the "make validate" target of the Makefile to validate the concatenated file containing all of your EADs.

Step 2: Concatentating the files into one larger XML file (and running some preprocessing commands)

cd $DLXSROOT/bin/w/workshopfa make prepdocs

The Makefile runs the following command:
$DLXSROOT/bin/w/workshopfa/preparedocs.pl $DLXSROOT/prep/w/workshopfa/data $DLXSROOT/obj/w/workshopfa/workshopfa.xml $DLXSROOT/prep/w/workshopfa/logfile.txt

This runs the preparedocs.pl script on all the files in the specified data directory and writes the output to the workshopfa.xml file in the appropriate /obj subdirectory. It also outputs a logfile to the /prep directory:

The Perl script does two sets of things:

1. Concatenates all the files
2. Runs a number of preprocessing steps on all the files

Concatenating the files

The script finds all XML files in the data subdirectory,and then strips off and xml declaration and doctype declaration from each file before concatenating them together. It also wraps the concatenated EADs in a <COLL> tag . The end result looks like:

<COLL>
<ead><eadheader><eadid>1</eadid>...</eadheader>... content</ead>
<ead><eadheader><eadid>2</eadid>...</eadheader>... content</ead>
<ead><eadheader><eadid>3</eadid>...</eadheader>... content</ead>
</COLL>

WARNING! If are extra characters or some other problem with the part of the program that strips out the xml declaration and the docytype declearation the file will end up like:

<COLL>
baddata<ead><eadheader><eadid>1</eadid>...</eadheader>... content</ead>
baddata<ead><eadheader><eadid>2</eadid>...</eadheader>... content</ead>
baddata<ead><eadheader><eadid>3</eadid>...</eadheader>... content</ead>
</COLL>

This will cause the document to be invalid since the dlxsead2002.dtd does not allow anything between the closing tag of one </ead> and the opening tag of the next one <ead>

Some of the possible causes of such a problem are:

• UTF-8 Byte Order Marks at the beginning of the file
• DOCTYPE declaration on more than one line
• XML processing instructions

Preprocessing steps

The perl program also does some preprocessing on all the files. These steps are customized to the needs of the Bentley. You should look at the perl code and modify it so it is appropriate for your encoding practices.

The preprocessing steps are:

• finds all id attributes and prepends a number to them
• adds a prefix string "dao-bhl" to all DAO links (You probably will want to change this)
• removes empty persname, corpname, and famname elements

The output of the combined concatenation and preprocessing steps will be the one collection named xml file which is deposited into the obj subdirectory.

If your collections need to be transformed in any way, or if you do not want the transformations to take place (the DAO changes, for example), edit preparedocs.pl file to effect the changes. Some changes you may want to make include:

• Changing the algorithm used to make id attibute unique. For example if your encoding practices use id attributes and targets, the out-of-the-box algorithm will remove the relationship between the attributes and targets. One possible modification might be to modify the algorithm to prepend the eadid or filename to all id and target attributes.
• Modifying the program to read a list of files or list of eadids so that the files are concatenated in a particular order. The default sort order for search results is in occurance order, which translates to the order in which the eads are concatenated. If you write a script which looks at the eads for some element that you want to sort by and then outputs a list of filenames sorted by that order, you could then pass that file to a modified preparedocs.pl so it would concatenate the files in the order listed.

Step 3: Validating the concatenated file against the dlxsead2002 DTD

make validate

The Makefile runs the following command:

onsgmls -wxml -s -f $DLXSROOT/prep/w/workshopfa/workshopfa.errors $DLXSROOT/misc/sgml/xml.dcl   $DLXSROOT/prep/w/workshopfa/workshopfa.xml.inp $DLXSROOT/obj/w/workshopfa/workshopfa.xml

This runs the onsgmls command against the concatenated file using the dlxs2002dtd, and writes any errors to the workshopfa.errors file in the appropriate subdirectory in $DLXSROOT/prep/c/collection.. | More details

Note that we are running this using workshopfa.xml.inp not workshop.text.inp. The workshopfa.xml.inp file points to $DLXSROOT/misc/sgml/dlxsead2002.ead which is the dlxsead2002 DTD. The dlxsead2002 DTDis exactly the same as the EAD2002 DTD, but adds a wrapping element, <COLL>, to be able to combine more than one ead element, more than one finding aid, into one file. The larger file will be indexed with XPAT tomorrow. It is, of course, a good idea to validate the file now before going further.

Run the following command

 ls -l $DLXSROOT/prep/w/workshopfa/workshopfa.errors

If there is a workshopfa.errors file then run the following command to look at the errors reported

 less $DLXSROOT/prep/w/workshopfa/workshopfa.errors

Common common causes of error messages and solutions

make: onsgmls: Command not found

OSGMLNORM variable in Makefile does not point to correct location of onsgmls for your installation or openSP is not installed.

If there were no errors when you ran "make validateeach" but you are now seeing errors

there was very likely a problem with the preparedocs.pl processing.

• The DOCTYPE declaration did not get completely removed. (The current scripts don't always remove multiline DOCTYPE declearations)
• There was a UTF-8 Byte Order Mark at the begginning of one or more of the concatenated files

onsgmls

/l1/dev/tburtonw/misc/sgml/xml.dcl:1:W: SGML declaration was not implied

The above error can be ignored, but if you see any other errors STOP! You need to determine the cause of the problem, fix it, and rerun the steps until there are no errors from make validate. If you continue with the next steps in the process with an invalid xml document, the errors will compound and it will be very difficult to trace the cause of the problem. To avoid seeing this error add the "-w no-explicit-sgml-decl" flag to the Makefile on line 83. Change line 83 of the Makefile

from:

onsgmls -wxml -s -f $(PREPDIR)$(NAMEPREFIX).errors $(XMLDECL) $(XMLDOCTYPE) $(XMLFILE)

to:

onsgmls -wxml -w no-explicit-sgml-decl -s -f $(PREPDIR)$(NAMEPREFIX).errors $(XMLDECL) $(XMLDOCTYPE) $(XMLFILE)

This will be fixed in the next release of DLXS Findaid Class.

Step 4: Normalizing the concatenated file

make norm

The Makefile runs a series of copy statements and two main commands:

1.)   /l/local/bin/osgmlnorm -f $DLXSROOT/prep/s/samplefa/samplefa.errors $DLXSROOT/misc/sgml/xml.dcl $DLXSROOT$DLXSROOT/prep/s/samplefa/samplefa.xml.inp $DLXSROOT/obj/s/samplefa/samplefa.xml.prenorm > /l1/dev/tburtonw/obj/s/samplefa/samplefa.xml.postnorm

2.)  /l/local/bin/osx -bUTF-8 -xlower -xempty -xno-nl-in-tag -f /l1/dev/tburtonw/prep/s/samplefa/samplefa.errors /l1/dev/tburtonw/misc/sgml/xml.dcl /l1/dev/tburtonw/prep/s/samplefa/samplefa.xml.inp /l1/dev/tburtonw/obj/s/samplefa/samplefa.xml.postnorm > /l1/dev/tburtonw/obj/s/samplefa/samplefa.xml.postnorm.osx 

These commands ensure that your collection data is normalized. What this means is that any attributes are put in the order in which they were defined in the DTD. Even though your collection data is XML and attribute order should be irrelevant (according to the XML specification), due to a bug in one of the supporting libraries used by xmlrgn (part of the indexing software), attributes must appear in the order that they are definded in the DTD. If you have "out-of-order" attributes and don't run make norm, you will get "invalid endpoints" errors during the make post step.

Step one, which normalizes the document writes its errors to $DLXSROOT/prep/s/samplefa/samplefa.errors. Be sure to check this file.

Step 2, which runs osx to convert the normalized document back into XML produces lots of error messages which are written to standard output. These are caused because we are using an XML DTD (the EAD 2002 DTD) and osx is using it to validate against the SGML document created by the osgmlnorm step. These are the only errors which may generally be ignored. However, if the next recommended step, which is to run "make validate" again reveals an invalid document, you may want to rerun osx and look at the errors for clues. (Only do this if you are sure that the problem is not being caused by XML processing instructions in the documents as explained below)

Step 5: Validating the normalized file against the dlxsead2002 DTD

make validate

We run this step again to make sure that the normalization process did not produce an invalid document. This is necessary because under some circumstances the "make norm" step can result in invalid XML. One known cause of this is the presense of XML processing instructions. For example: "<?Pub Caret1?>". Although XML processing instructions are supposed to be ignored by any XML application that does not understand them, the problem is that when we use sgmlnorm and osx, which are SGML tools, they end up munging the output XML. The recommended workaround is to add a preprocessing step to remove any XML processing instructions from your EADs before you run "make prepdocs", or to include some code in preparedocs.pl that will strip out XML priocessing instructions prior to concatenating the EADs.

Building the Index

After you have followed all the steps to set up your directories and prepare your files, as described in Validating and Normalizing Your Data, indexing the collection is fairly straightforward. To create an index for use with the Findaid Class interface, you will need to index the words in the collection, then index the XML (the structural metadata, if you will), and then finally "fabricate" regions based on a combination of elements (for example, defining what the "main entry" is, without adding a <MAINENTRY> tag around the appropriate <AUTHOR> or <TITLE> element).

The main work in the indexing step is making sure that the fabricated regions in the workshopfa.extra.srch file match the characteristics of your collection.

Note: If the final "make validate" step in Data Preparation Step 5:Validating the normalized file against the dlxsead2002 DTD produced errors, you will need to fix the problem before running the indexing steps. Attempting to index an invalid document will lead to indexing problems and/or corrupt indexes.

The Makefile in the $DLXSROOT/bin/c/collection directory contains the commands necessary to build the index, and can be executed easily.

To create an index for use with the Findaid Class interface, you will need to index the words in the collection, then index the XML (the structural metadata, if you will), and then finally "fabricate" structures based on a combination of elements (for example, defining who the "main author" of a finding aid is, without adding a <mainauthor> tag around the appropriate <author> in the eadheader element). The following commands can be used to make the index:

The Makefile should be in the $DLXSROOT/bin/c/collection directory.

cd $DLXSROOT/bin/c/collection

make singledd indexes words for texts that have been concatenated into one large file for a collection. This is the recommended process.

make xml indexes the XML structure by reading the DTD. It validates as it indexes.

make post builds and indexes fabricated regions based on the XPAT queries stored in the workshopfa.extra.srch file. Because every collection is different, this file will need to be adapted after you have determined what you want to use as the "main title" for a finding aid (e.g., perhaps the ORIGINATION within the DID within the ARCHDESC) and how many levels of components (e.g., nested to C04) you have in your collection. If you try to index/build fabricated regions from elements not used in your finding aids collection, you will see errors like Error found: <Error>syntax error before: ")</Error> when you use the make post command

Step by Step Instructions for Indexing

Step 1: Indexing the text

 cd $DLXSROOT/bin/w/workshopfa
 make singledd

The make file runs the following commands:

 cp /l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.blank.dd
 	/l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 /l/local/xpat/bin/xpatbld -m 256m -D /l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 cp /l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 	/l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.presgml.dd

Step 2: Indexing the the XML

 make xml

The makefile runs the following commands:

 cp /l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.presgml.dd
 	/l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 /l/local/xpat/bin/xmlrgn -D /l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 	/l1/workshop/test02/dlxs/misc/sgml/xml.dcl
 	/l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.inp
 	/l1/workshop/test02/dlxs/obj/w/workshopfa/workshopfa.xml
 
 cp /l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 	/l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.prepost.dd

Step 3: Configuring fabricated regions

Fabricated regions are set up in the $DLXSROOT/prep/c/collection/collection.extra.srch file. The sample file $DLXSROOT/prep/s/samplefa/samplefa.extra.srch was designed for use with the Bentley's encoding practices. If your encoding practices differ from the Bentley's, or if your collection does not have all the elements that the samplefa.extra.srch xpat queries expect, you will need to edit your *.extra.srch file.

We recommend a combination of the following:

1. Iterative work to insure make post does not report errors
2. Iterative work to insure that searching and rendering work properly with your encoding practices.
3. Up front analysis

Run the "make post" and iterate until there are no errors reported.

Run the "make post" step and look at the errors reported. Then modify *.extra.srch and rerun "make post". Repeat this until "make post" does not report any errors.

The most common cause of "make post" errors related to fabricated regions result from a fabricated region being defined which includes an element which is not in your collection.

For example if you do not have any <corpname> elements in any of the EADs in your collection and you are using the out-of-the-box samplefa.extra.srch, you will see an error message when xpat tries to index the mainauthor region using this rule:

(
     (region "persname" + region "corpname" + region "famname" + region "name")
      within 
       (region "origination" within 
          ( region "did" within 
               (region "archdesc")
          )
       )
      ); 
{exportfile /l1/workshop/user11/dlxs/idx/s/samplefa/mainauthor.rgn"}; export;~sync "mainauthor"; 

If you don't expect to ever use an element, then you can eliminate it from the fabricated region definitions. An alternative that is useful if you have only a small sample of the EADs you will be mounting and you expect that some of the EADs you will be getting later might have the element that is currently missing from your collection, is to add a "dummy" EAD to your collection. The "dummy" ead should contains all the elements you will ever expect to use (or that are required by the *.extra.srch file). The "dummy" EAD should have all elements except the <eadid> empty.

Exercise the web user interface

Once make post does not report errors, you can follow the rest of the steps to put your collection on the web. Then carefully exercise the web user interface looking for the following symptoms:

• Searches that don't work properly because they depend on fabricated regions that don't match your encoding practices.
• Rendering that does not work properly. (An example is that the name/title of the finding aid may not show up if your <unititle> element precedes your <origination> element in the top level <did>.)

For more information on regions used for searching and rendering see

• Working with Fabricated Regions in Findaid Class

• Fabricated regions required in Findaid Class
• Fabricated regions commonly found in Findaid Class

Analysis of your collection

You may be able to analyze your collection prior to running make post and determine what changes you want to make in the fabricated regions. If your analysis misses any changes, you can find this out by using the two previous techniques.

• Once you have run "make xml", but before you run "make post", start up xpatu running against the newly created indexes:

 xpatu $DLXSROOT/idx/s/samplefa/samplefa.dd

then run the command

 >> {ddinfo regionnames}

This will give you a list of all the XML elements, and attributes

Alternatively you can create a file called xpatregions and insert the following text:

{ddinfo regionnames}

Then run this command

$ xpatu /l1/dev/tburtonw/idx/s/samplefa/samplefa.dd < xpatregions > regions.out

see desktop findaidwiki.rtf Reference to more details on fab regions in findaid class goes here

Step 4: Indexing fabricated regions

 make post

The makefile runs the following commands:

 cp /l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.prepost.dd
 	/l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 touch /l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.init
 /l/local/xpat/bin/xpat -q /l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd
 	< /l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.extra.srch
 	| /l1/workshop/test02/dlxs/bin/t/text/output.dd.frag.pl
 	/l1/workshop/test02/dlxs/idx/w/workshopfa/
 	> /l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.extra.dd
 /l1/workshop/test02/dlxs/bin/t/text/inc.extra.dd.pl
 	/l1/workshop/test02/dlxs/prep/w/workshopfa/workshopfa.extra.dd
 	/l1/workshop/test02/dlxs/idx/w/workshopfa/workshopfa.dd

If you get an "invalid endpoints" message from "make post", the most likely cause is XML processing instructions or some other corruption. The second "make validate" step should have caught these. Other possible causes of errors during the "make post" step include syntax errors in workshopfa.extra.srch, or the absense of a particular region that is listed in the *.extra.srch file but not present in your collection. For example if you do not have any <corpname> elements in any of the EADs in your collection and you are using the out-of-the-box samplefa.extra.srch, you will see an error message when xpat tries to index the mainauthor region using this rule:

((region "persname" + region "corpname" + region "famname" + region "name") within (region "origination" within ( re gion "did" within (region "archdesc")))); {exportfile "/l1/workshop/user11/dlxs/idx/s/samplefa/mainauthor.rgn"}; exp ort; ~sync "mainauthor";

The easiest solution is to modify *extra.srch to match the characteristics of your collection. An alternative is to include a "dummy" EAD that contains all the elements that you expect in your collection with no content

Testing the index

At this point it is a good idea to do some testing of the newly created index. Strategically, it is good to test this from a directory other than the one you indexed in, to ensure that relative or absolute paths are resolving appropriately. Invoke xpat with the following command

xpatu $DLXSROOT/idx/w/workshopfa/workshopfa.dd

For more information about searching, see the XPAT manual.

Try searching for some likely regions. Its a good idea to test some of the fabricated regions. Here are a few sample queries:

>> region "ead"
  1: 3 matches

>> region "eadheader"
  2: 3 matches

>> region "mainauthor"
  3: 3 matches

>> region "maintitle"
  4: 3 matches

>> region "admininfo"
  5: 3 matches

Working with Fabricated Regions in Findaid Class

When you use XPAT in combination with xmlrgn and a DTD, you are identifying the elements and attributes in the DTD or tags file as "regions," containers of content rather like fields in a database. These separate regions are built into the regions file (collid.rgn) and are identified in the data dictionary (collid.dd). This is what is happening when you are running xmlrgn.

However, sometimes the things you want to identify collectively aren't so handily identified as elements in the DTD. For example, the Findaid Class search interface can allow the user to search in Names regions. Perhaps for your collection you want Names to include persname, corpname, geoname. By creating an XPAT query that ORs these regions, you can have XPAT index all the regions that satisfy the OR-ed query. For example:

(region "name" + region "persname" + region "corpname" + region "geoname" +
region "famname")

Once you have a query that produces the results you want, you can add an entry to the *.extra.srch file which (when you run the "make post" command) will run the query, create a file for export, export it, and sync it:

{exportfile "$DLXSROOT/idx/c/collid/names.rgn"} export ~sync "names"

Why fabricate regions? Why not just put these queries in the map file and call them names? While you could, it's probably worth your time to build these succinctly-named and precompiled regions; query errors are more easily identified in the index building than in the CGI, and XPAT searches can be simpler and quicker for terms within the prebuilt regions.

Fabricated regions within the Findaid Class can be found in the extra.srch file for the sample collection at $DLXSROOT/prep/s/samplefa/samplefa.extra.srch. As with any other elements used in the interface for a given collection, fabricated regions used in the user interface, such as the names of searches available in the dropdown menu of the search box, must also be represented in the collmgr entry and the map file for that collection.

The middleware for Findaid Class uses a number of fabricated regions in order to speed up xpat queries and simplify coding and configuration.

Findaid Class uses fabricated regions for several purposes

1. To share code with Text Class (e.g. region main)
2. Fabricated regions for searching (e.g. region names)
3. Fabricated regions to produce the Table of Contents and to implement display of EAD sections as focused regions such as the "Title Page" or "Arrangement" ( See Working with the table of contents for more information on the use of fabricated regions for the table of contents.)
4. Other regions specifically used in a PI (region maintitle is used by the PI <?ITEM_TITLE_XML?> used to display the title of a finding aid at the top of each page)

test of preformated text
foo bar

The fabricated region "main" is set to refer to <ead> in FindaidClass with:

(region ead); {exportfile "/l1/idx/b/bhlead/main.rgn"}; export; ~sync "main";

whereas in TextClass "main" can refer to <TEXT>. Therfore, both FindaidClass and TextClass can share the Perl code, in a higher level subclass, that creates searches for "main".

Other fabricated regions are used for searching such as the maintitle and mainauthor regions.

temp toc fab regions

The majority of the fabricated regions for Findaid Class are used for the creation and display of the left hand table of contents in the "outline" view. The findaidclass.cfg file contains a hash called %gSectHeadsHash which is normally loaded into FindaidClass.pm's tocheads hash in the FindaidClass::_initialize method. The elements of the hash and the corresponding fabiricated regions are used to create the table of contents and to output the XML for the corresponding section of the EAD when one of the TOC links is clicked on by a user. The fabricated regions are used so XPAT can have binary indexes ready to use for fast retrieval of these EAD sections. See #Working_with_the_table_of_contents Customizing Findaid Class:Working with the table of contents for more information on the use of fabricated regions for the table of contents.

Some of the more interesting regions extracted from the samplefa.extra.srch file are listed below.

One of these regions is the add. This used to be <ADD> in the EAD 1.0 DTD, but now, is created based on the ead2002 DTD's <descgrp> tag which contains a type attribute of add.

A number of issues related to varying encoding practices can be resolved by the appropriate edits to the *.extra.srch file. (Although some of them may require changes to other files as well)

• If your <unititle> element precedes your <origination> element in the top level <did>, you will have to modify the "maintitle" fabricated region query in *.extra.srch
• If you do not use a <frontmatter> element, you will have to make modifications to various files including modifying *.extra.srch to provide an appropriate "Title Page" region based on the <eadheader>
• If your encoding practices for <biohist> differ from the Bentley's, you may need to make changes in the <bioghist> fabricated region although changes to other files may be suffient. The changes might include: modifying findaidclass.cfg or creating a subclass of FindaidClass and override FindaidClass:: GetBioghistTocHead, and/or changing the appropriate XSL files.
• If you want sections of the finding aid that are not completely within a well-defined element such as <relatedmaterial>or <separatedmaterial> to show up in the table of contents, you may have to create a fabricated region using the appropriate xpat query and then modify findaidclass.cfg and make other modifications to the code.

Customizing Findaid Class

Working with the table of contents

The table of contents on the left-hand side of the finding aid display is based on fabricated regions set up in *.extra.srch and configured either in a configuration file or in a subclass of FindaidClass.pm

If a subclass is not being used to override the FindaidClass::_initialize method, the configuration file will either be:

$DLXSROOT/cgi/f/findaidclass/findaidclass.cfg 

or in a collection-specific config file

$DLXSROOT/cgi/s/samplefa/findaidclass.cfg (tbw verify this/ask phil)

The configuration file sets up a hash called %gSectHeadsHash. The relevant section of the findaidclass.cfg file is:

# **********************************************************************
# Hash of section heads that XPAT should search for.  A reference to
# this hash is added as member data keyed by 'tocheads' to the
# FindaidClass object at initialization time. Comment out those that
# are missing in your finding aids.
# **********************************************************************
%gSectHeadsHash = (
                  'bioghist-t'      =>  {
                                         'collection' => qq{Biography},
                                         'recordgrp' => qq{History},
                                        },
                  'controlaccess-t' => qq{Subject Terms},
                  'frontmatter-t'   => qq{Title Page},
                  'arrangement-t'   => qq{Arrangement},
                  'scopecontent-t'  => qq{Collection Scope and Content Note},
                  'summaryinfo-t'   => qq{Summary Information},
                  'contentslist-t'  => qq{Contents List},
                  'admininfo-t'     => qq{Access and Use},
                  'add-t'           => qq{Additional Descriptive Data},
                 );

The %gSectHeadsHash is normally loaded read from the configuration file and loaded into a hash called tocheads in the FindaidClass::_initialize method when the FindaidClass object is created. If you wish to change the table of contents on a collection-specific basis, you can override the FindaidClass::_initialize method in a collection-specific subclass.

For an example of using a subclass to override the default table of contents see: $DLXSROOT/cgi/f/findaid/FindaidClass/SamplefaFC.pm

Note that the default setting in the Collection Manager for the samplefa collection is to use this subclass:

insert image of subclass coll mgr here.

The diagram below shows the fabricated region and the corresponding EAD element tags for the out-of-the-box table of contents

Mounting the Collection Online

[#Top go to table of contents]

tbw revise to demo copy command to copy from samplefa to my_coll instead of talking about workshopfa

These are the final steps in deploying an Findaid Class collection online. Here the Collection Manager will be used to review the Collection Database entry for workshopfa . The Collection Manager will also be used to check the Group Database. Finally, we need to work with the collection map and the set up the collection's web directory.

Review the Collection Database Entry with CollMgr

Each collection has a record in the collection database that holds collection specific configurations for the middleware. CollMgr (Collection Manager) is a web based interface to the collection database that provides functionality for editing each collection's record. Collections can be checked-out for editing, checked-in for testing, and released to production. In general, a new collection needs to have a CollMgr record created from scratch before the middleware can be used. If you are starting with the samplefa collmgr as a model make sure to change references from s/samplefa to w/workshopfa or whatever you are using for your collection name.

tbw: Add instructions re: using copy function to copy samplefa collmgr entries to my_findaids entry. Possibly note particular fields, esp subclass currently implemented for Samplefa!

Add reminder that password/username for collmgr probably set up in apache basic auth for directory. add example.

Add generic url for collmgr.

First, create a collection database record using the unique ID you selected for your collection. Each entry must exactly match, in case and pluralization, its counterpart in the map file. What should go here that isn't in a general collection manager section?

Review the Groups Database Entry with CollMgr

Another function of CollMgr allows the grouping of collections for cross-collection searching. Any number of collection groups may be created for Findaid Class. Findaid Class supports a group with the groupid "all". It is not a requirement that all collections be in this group, though that's the basic idea. Groups are created and modified using CollMgr.

Make Collection Map

Collection mapper files exist to identify the regions and operators used by the middleware when interacting with the search forms. Each collection will need one, but most collections can use a fairly standard map file, such as the one in the samplefa collection. The map files for all Findaid Class collections are stored in $DLXSROOT/misc/f/findaid/maps

Map files take language that is used in the forms and translates it into language for the cgi and for XPAT. For example, if you want your users to be able to search within names, you would need to add a mapping for how you want it to appear in the search interface (case is important, as is pluralization!), how the cgi variable would be set (usually all caps, and not stepping on an existing variable), and how XPAT will identify and retrieve this natively (in XPAT search language).

The first part of the map file is operator mapping, for the form, the cgi, and XPAT. The second part is for region mapping, as in the example above.

cd $DLXSROOT/misc/f/findaid/maps
cp samplefa.map workshopfa.map

You might note that some of the fields that are defined in the map file correspond to some of the [#FabRegions fabricated regions].

1. Make the Collection Map Collection mapper files exist to identify the regions and operators used by the middleware when interacting with the search forms. Each collection will need one, but most collections can use a fairly standard map file, such as the one in the samplefa collection. The map files for all Findaid Class collections are stored in $DLXSROOT/misc/f/findaid/maps. Map files contain mapped items where one term or name for the item is mapped to another term or name. For example, a term used by an HTML form to refer to a searchable region (e.g., "entire finding aid") can be mapped to an XPAT searchable region (e.g., EAD). For more general background on map files, see DLXS Map Files. Currently, the format of the map files is XML and each collection map file conforms to a simple DTD (we have considered implementation of other possible ways of mapping terms, such as a database where one could map from one column's data to another). The middleware reads the map file into a TerminologyMapper object after which the CGI program can at any time request of the object the mappings for terms. Each mapped item and its various terms are contained within a <MAPPING> element. You can find an example map file for the sample finding aids collection at $DLXSROOT/misc/f/findaid/maps/samplefa.map. Rather than modifying this file, you should copy it so that you always have a blank copy to which to refer. Each mapping element in a map file consists of the following: label: This element determines what will display in the user's browser when constructing searches. It must match the value used in the collmgr. (See step 2.) synthetic: This element contains the variable name as it is used in the cgi. native: The "native" element provides an appropriate XPAT search that the system will use to discover the appropriate content. The search may be simple (e.g., region EADID) or complex (e.g., ((region DID within region ARCHDESC) not within region DSC)) nativeregionname: The element name itself, as it is indexed, without terms used in the XPAT search. Map files take language that is used in the forms and translates it into language for the cgi and for XPAT. For example, if you want your users to be able to search within names, you need to add a mapping for how you want headings and categories to appear in the search interface (case is important, as is pluralization!), how the cgi variable is set (usually in all caps, and not stepping on an existing variable), and how XPAT will identify and retrieve this natively (in XPAT search language). The first part of the map file is operator mapping, for the form, the cgi, and XPAT, and the second part is for region mapping. You might note that some of the fields that are defined in the map file correspond to some of the fabricated regions. Note: The larger the map file, the slower your site will run, so you don’t necessarily want to map everything, such as variations of singular and plural fields. For more information see DLXS Map Files.

Set Up the Collection's Web Directory

Each collection may have a web directory with custom Cascading Style Sheets, interface templates, graphics, and javascript. The default is for a collection to use the web templates at $DLXSROOT/web/f/findaid. Of course, collection specific templates and other files can be placed in a collection specific web directory, and it is necessary if you have any customization at all. DLXS Middleware uses [../ui/index.html#fallback fallback] to find HTML related templates, chunks, graphics, js and css files.

For a minimal collection, you will want two files: index.html and FindaidClass-specific.css.

mkdir -p $DLXSROOT/web/w/workshopfa cp $DLXSROOT/web/s/samplefa/index.html $DLXSROOT/web/w/workshopfa/index.html cp $DLXSROOT/web/s/samplefa/findaidclass-specific.css $DLXSROOT/web/w/workshopfa/findaidclass-specific.css

As always, we'll need to change the collection name and paths. You might want to change the look radically, if your HTML skills are up to it.

Note that the browse link on the index.html page is hard-coded to go to the samplefa hard-coded browse.html page. You may want to change this to point to a dynamic browse page (see below). The url for the dynamic browse page is ".../cgi/f/findaid/findaid-idx?c=workshopfa;page=browse".

If you would prefer a dynamic home page, you can copy and modify the home.xml and home.xsl files from $DLXSROOT/web/f/findaid/. Note that they are currently set up to be the home page for all finding aids collections, so you will have to do some considerable editing. However they contain a number of PIs that you may find useful. In order to have these pages actually be used by DLXS, they have to be present in your $DLXSROOT/web/w/workshopfa/ directory and there can't be an index.html page in that directory. The easiest thing to do, if you have an existing index.html page is to rename it to "index.html.foobar" or something.

Common Problems and Solutions

Title of Finding Aid does not show up

This is usually caused by the <origination> preceding the <unittitle> in the top level <did> element of your EAD

In the *.extra.srch file

comment out the following line:

(note that the region definitions are all on one line, but have been wrapped so they will be readable in the wiki)

##
((region "<origination".."</unittitle>") 
within ((region did within region archdesc)
not within region dsc));
{exportfile "/l1/release/13/idx/s/samplefa/maintitle.rgn"}; 
 export; ~sync "maintitle";
##

copy the line but reverse the order of unittitle and origination

##
((region "<unittitle".."</origination>") 
within ((region did within region archdesc)
not within region dsc));
{exportfile "/l1/release/13/idx/s/samplefa/maintitle.rgn"}; 
export; ~sync "maintitle";

Linking from Finding Aids Using ID Resolver

[#Top go to table of contents]

How do you do this?

Findaid Class is coded so that if there is an href attribute to the <dao> element, it will check to see if it contains the string "http". If it does, FindaidClass will not us ID Resolver, but will create a link based on the content of the href attribute of the <dao>. If there is no "http" string in the href attribute, FindaidClass assumes that the href attribute is actully an id and will look up that id in in the idresolver and build a link if it finds the ID in the IDRESOLVER table. The method FilterAllDaos_XML in $DLXSROOT/cgi/f/findaid/FindaidClass.pm can be overridden per collection if different behavior is needed.

If you decide to use this feature, you will want to modify the preprocessing script preparedocs.pl which out-of-the-box inserts the string 'dao-bhl-' after the href. Below is an example of a Bentley <dao> where the id number is 91153-1.

<dao linktype="simple" href="91153-1" show="new" actuate="onrequest">
         <daodesc>
          <p>[view selected images]</p>
         </daodesc>
        </dao>

The preparedocs.pl program would change this to:

<dao linktype="simple" href="dao-bhl-91153-1" show="new" actuate="onrequest">
         <daodesc>
          <p>[view selected images]</p>
         </daodesc>
        </dao>

The ID resolver would look up the id "dao-bhl-91153-1" and replace it with the appropriate URL.

ID Resolver Data Transformation and Deployment

The ID Resolver is a CGI that takes as input a unique identifier and returns a URI. It is used, for example, by Harper's Weekly to link the text pages in Text Class middleware to the image pages in the Image Class middleware, and vice versa.

Plug something like the following in to your web browser and you should get something back. If you choose to test middleware on a development machine that uses the id resolver, make sure that the middleware on that machine is calling the resolver on the machine with the data, and not the resolver on the production server.

• http://clamato.hti.umich.edu/cgi/i/idresolver/idresolver?id=dao-bhl-bl000684
• which should yield...
  <ITEM MTIME="20030728142225"><ID>dao-bhl-bl000684 </ID><URI>http://images.umdl.umich.edu/cgi/i/image/image-idx?&q1=bl000684&rgn1=bhl_href&type=boolean&med=1&view=thumbnail&c=bhl </URI></ITEM>
