Identifiers for UK OER “works”

Would it be useful and feasible to have a single identifier to link together all the instances of a learning resource? To be more specific, consider a lecture that has been videoed. The video is available on YouTube, in a national repository, and from the website of the institution where it was delivered (also bear in mind that there might be an audio-only recording and written transcripts of the same lecture). Should there be an HTTP URI that relates (indirectly) to all of these versions of the same lecture?

The reason I’m asking is because we are trying to define what should be the technical and metadata requirements for materials produced through the HEFCE/JISC/HE Academy OER funding. I’m suggesting a short URI that can be used to refer to any version of a work; as I envisage this it would resolve to a list of all the known versions. I think this is important for accessibility (in its widest sense), sustainability, and for collating information about a resource that may be available all over the place. The problems centre on the difficulty of understanding the concepts involved, and are especially acute because the implementation cannot be done just by the people who currently understand the issues involved.

TILE: Libraries, usage data and recommendation

Tesco know how old my children are. They know this because, through tracking what we buy online or using a loyalty card, they know when we started to buy nappies and baby talc. They have used this information to send us special offer vouchers for baby foods etc. The library at my home institution have similar information about students’ borrowing habits and in principle have access to information about what courses the students were enrolled on and what they access through the VLE. This information was described as a goldmine, but libraries don’t use it. This workshop was about how they might use it, with the related questions of should they and could they.

The learning content management repository virtual environment system 2.0 and its future, summarized

As I explained earlier, at this year’s JISC CETIS conference I was in charge of running a session comparing content management, virtual learning and repository systems. I’ve just finished updating the session page on the wiki with links to all the presentations and commentaries available from the day. Here are my own summary and reflections on the session.

FRBRizing learning materials

I may have bitten off more than I can chew. I wanted an example for showing how the Functional Requirements for Bibliographic Records (FRBR) might be applied to a typical learning resource. I’m not entirely sure that there is such a thing as a typical learning resource, but the OpenYale online lectures seemed seemed like reasonable candidates. I chose one on Newton’s Laws of Motion as my example because it’s a subject I like. I’m no expert on FRBR. If I was I would probably have known better than to choose a complex aggregation of different media types as my example (but would that have been typical?). Anyway, with some help from John Robertson, I came up with the diagram below. (It doesn’t quite model the example: I’ve modelled overhead display content in PowerPoint rather than in chalk.)
Application of FRBR model to online course unit

I’ve described the modelling and rationale in some more detail in a separate document [pdf].

I would warmly welcome any comments, suggestions and pointers to where I’ve gone wrong.

OAI-ORE 1.0 released

The first production release of the Open Archives Initiative Object Reuse and Exchange (OAI-ORE) specification was published last Friday (17 Oct). OAI-ORE uses concepts from the web architecture, semantic web, linked data and Atom syndication to expose the relationships between parts of an aggregation, e.g. linked web pages, different formats of the same publication, chapters in an online book, and collections of documents, photos or recordings. OAI-ORE comes from the scholarly publication community, but has wider application: it’s sort of equivalent to parts of the manifest in an IMS Content Package, but with more emphasis on showing relationships between resources on the web and rather than describing what should be in a package and how it should be displayed.
