OER Platform Comparison


Image:OERplatform sm1.jpg

Producing - Authoring content

 - Making open content available to content authors. How can this
system be bootstrapped so faculty authors can start with open
content

- Image library

 - Multi institution
- Federated search so institutions benefit from stuff others have
cleared already

Content repository (general) - Should it be backing campus LMS and OER to prevent multiple copies allow access on OER/OCW site by changing access control after IP clearance and obtaining permission? - Implicit to this is that whatever content repository is adopted should provide rich support for ACLs, users, group - For UM it would require that we have content available at a very granular level in repository (individual CO). - Which content repository lends itself well to being a general store. Similar to a DB and filesystem combo like current OERca, Flickr. - Advantages of using content repository

 - DSpace, DLXS provide static "handles" which prevent broken
links.

- How do general content repository and image library

 coexist. Should it be just image library or should it be
generalized across all content types. Again, different front-end and
access controlled using ACLs (flipping an Open Content switch)

Processing - Clearing content

 - Currently a need since faculty aren't generally savvy to the
practice of using CC or other openly licensed content
- Laborious process and every institution has their own tools to
support their process.
- Can we have a general tool that is flexible enough to work for all
our efforts?

- Metadata

 - Everybody knows it is necessary
- But nobody wants to be the one adding it. It's very laborious.
- What do we want to add?
- What standard/s should we conform to?
- Should any tool adopted/created allow for multiple metadata
schemes?
- Ease the pain of annotation.
- Drag and drop.
- Automate as much as possible using other processing "services"
- Inherit from "parent" entities

- A/V

 - Automated transcoding
- enabling access on slower connections, smaller screens, lower
power devices
- original full fidelity format is still available
- can transcode from proprietary to open formats e.g. mp3 to
ogg-vorbis audio
- may optionally facilitate streaming
- key-frame extraction from video
- automated detection of average bitrate, codec, aspect ratio (as
possible)
- speech to text, to allow subtitles
- closely coupled to metadata issue since format/codec metadata
can be autodetected, may be added to file or perhaps can be
exported in a separate text file

- Document processing

 - Detect, extract and contextualize content objects embedded in
office files (MS Office, OpenOffice, iWork)
- Detect file format, image size etc.
- Should this be embedded in CO or in a separate file

Publishing - Formalized workflow to allow correct checking of content before publishing. Different from what OERca offers, this is to prevent spelling/formatting errors.

Presenting - Allow access to content at a very granular level.

 - Design should prevent users from being overwhelmed by too much
choice. Current Connexions design gives too many results, cannot
refine search further.

- Some authoring functionality?

 - To facilitate remixing of content. How else should it be done
without authoring functionality.
- Perhaps make it easy to download open content, and provide
pointers to desktop tools to do remixing/enhancement? Will this
raise the barrier too high to get participation

Preserving - Making this a separate step, in which archived content is moved to less responsive storage may be a mistake. - Should preserving simply be backup or content repository. - Older courses should be equally available as newer ones? - Any preservation system should allow direct import from existing web resources. Perhaps as IMSCP?
