What technology is being used to aggregate open educational resources? What role can the subject community play in resources discovery? This is a post in the UKOER 2 technical synthesis series.

In the UKOER 2 programme Strand C funded “Projects identifying, collecting and promoting collections of OER and other material around a common theme” with the aim “…to investigate how thematic and subject area presentation of OER material can make resources more discoverable by those working in these areas” (UKOER 2 call document). The projects had to create what were termed static and dynamic collections of OER. The intent of the static collection was that it could in some way act as an identity, focus, or seed for the dynamic collection. Six projects were funded: CSAP OEROerbitalDelOREsTritonEALCFOOpen Fieldwork and a range of approaches and technologies was taken to making both static and dynamic collections. The projects are all worth reading about in more detail – however, in this context there are two possible general patterns worth considering.


Technology

The above graph shows the range of technology used in the Strand. Although a lot could (and should) be said about each project individually when their choices are viewed in aggregate the following technologies are seeing the widest use.

Although aspects of the call might have shaped the projects’ technical choices to some extent, a few things stand out:

  • the focus on RSS/Atom feeds and tools to manipulate them
    • reflection: this matches the approach taken by many of the other  aggregators and discovery services  for OER and other learning materials as well as the built in capabilities of a number of the platforms in use [nb "syndicated via RSS/Atom" was a programme requirement]
  • a relative lack of a use of OAI-PMH
    • reflection: is this indicative of how many content providers and aggregators in the learning material’s consume or output OAI-PMH?
  • substantial use or investigation of wordpress and custom databases (with php frontends)
    • reflection: are repositories irrelevant here because they don’t offer easy ways to add plugins or aggregate others’ content (or are there other factors which make WordPress and a custom database more appealing)

Community

One of the critical issues for all of these projects in the creation of these collections has been the role of community; for some of the strand projects the subject community played a crucial role in developing the static collection which then fed, framed, or seeded the dynamic collection, for other projects the subject community formed the basis of contributing resources to the dynamic collection.

Although the projects had to be “closely aligned with relevant subject or thematic networks – for example Academy Subject Centres, professional bodies and national subject associations” , I find it striking that many of the projects made those defined communities an integral part of their discovery process and not just an audience or defining domain.

Reflections on community

I’m hoping someone else is able to explore the role of community in discovery services more fully (if not I’ll try to come back to this)  but I’ve been struck by the model used by some projects in which a community platform is the hook leading to resource discovery. It’s the opposite end of the spectrum to Google – to support discovery you create a place and content accessible and relevant to a specific subject domain. The place you create both hosts new content created by a specific community and serves as a starting point to point to further resources elsewhere (whether those pointers are links, learning pathways, or tweaked plugin searches run on aggregators or repositories). This pattern mirrors any number of thriving community sites (typically?) outside of academia that happily coexist in Google’s world providing specialist sources of information and community portals  (for example about knitting, cooking, boardgames).

What it doesn’t mirror is trying to entice academics to use a repository… [I like repositories and think they're very useful for some things , but this and the examples of layering CMSs on top of repositories, increasingly makes me think that on their own they aren't a great point of engagement for anybody...]

Dissemination protocols

Dissemination protocols in use in the UKOER 2 programme

The chosen dissemination protocols are usually already built in the platforms in use by projects; adding or customising an RSS feed is possible but often intricate and adding an OAI-PMH feed is likely to require substantial technical development. DelOREs investigated existing OAI-PMH plugins for WordPress they could use but didn’t find anything usable within their project.

As will be discussed in more detail when considering Strand C – RSS is not only the most supported dissemination protocol, from the programme’s evidence, it is also the most used in building specialist discovery services for learning and teaching materials. The demand for an OAI-PMH interface for learning resources remains unknown. [debate!]

Jorum representation

Methods of uploading to Jorum chosen in UKOER 2 programme

Methods of uploading to Jorum chosen in UKOER 2 programme

  • The statistics on Jorum upload method are denoted expressions of intent – projects and Jorum are still working through these options.
  • Currently RSS upload to Jorum (along with all other forms of bulk upload) is set up to create a metadata record not deposit content.
  • Three of the uploaders using RSS are using the edshare/eprints platform (this platform was successfully configured to deposit metadata in bulk  via RSS into Jorum in UKOER phase 1).
  • Jorum uses RSS ingest as a one-time process – as I understand it it does not revisit the feed for changes or updates [TBC]
  • As far as I know PORSCHE are the only project who have an arranged OAI-PMH based harvest (experimental for Jorum upload under investigation as part of an independent project – [thanks to Nick Shepherd for the update on this HEFCE-funded work: see comments and more information is available on the ACErep blog)]
