As some of you may have heard by now, yesterday was my last day working at Eduserv. In a few weeks, I'll be taking up a post at Cambridge University Library, working on metadata for their Digital Library. This feels... Continue reading

I'm currently doing a piece of work on representing a thesaurus as linked data. I'm working on the basis that the output will make use of the SKOS model/RDF vocabulary. Some of the questions I'm pondering are probably SKOS Frequently... Continue reading

Contrary to appearances, I haven't completely abandoned eFoundations, but recently I've mostly been working on the JISC-funded LOCAH project which I mentioned here a while ago, and my recent scribblings have mostly been over on the project blog. LOCAH is... Continue reading

@Paul, Just to add some background to Andy's response, it might be helpful to look at the paper I referred to from the ProLEARN project: Harmonization of Metadata Standards http://ariadne.cs.kuleuven.be/lomi/images/5/52/D4.7-prolearn.pdf It tries to summarise the role of "abstract models" in metadata standards, and how the compatability or incompatability of the abstract models used by different metadata standards impacts on interoperability between applications based on them. It acknowledges that cross-community consensus on abstract models does not yet exist, but makes some pragmatic recommendations: For abstract models, a consensus has yet to be reached, although the Resource Description Framework (RDF) does provide a framework well founded in Web architecture and a formal semantics. This deliverable still recommends that metadata specifications harmonize their models with the RDF model and, by extension, the semantic web. This - harmonizing the (previously loosely/informally defined) "abstract model" of the DCMI community with RDF - is the step we tried to take with the DCMI Abstract Model, and we took it because it was felt that RDF/RDF Schema are designed to try to address many of the requirements for metadata identified within that community, mentioned in section 4 of the paper. The paper also tries to highlight the problems arising from introducing more community-/domain-specific abstract models: Discourage the introduction of new abstract models into the domain, as this further fragments the community. If DCMI had not adopted the RDF model, and sought instead to develop an abstract model not based on RDF, we'd be contributing to exactly this problem, and further hindering interoperability. P.S. Mikael's (currently draft, but hopefully soon to be published) PhD thesis goes into these issues (and other related issues) in more detail, and will be a jolly good read. P.P.S. I tried to think up some maritime metaphors but failed :)

Just in case there is any ambiguity in my position, I am arguing that DCMI should state clearly that: - the data model for Dublin Core metadata is the RDF triple/graph data model as defined by RDF Concepts and Abstract Syntax http://www.w3.org/TR/rdf-concepts/ - the formal semantics for Dublin Core metadata are those defined by RDF & RDF Schema http://www.w3.org/TR/rdf-mt/ http://www.w3.org/TR/rdf-schema/ The question of "validation"/"structural constraints" (currently addressed within DCMI in the draft DSP specification) should be explored within the wider Linked Data/Semantic Web community, with the aim of finding solutions based on the RDF graph/triple model. I don't know whether anything needs to be said about OWL (but note that DCMI's descriptions of its terms do now make use of some OWL constructs). I would like to see DCMI make this commitment to the RDF standards clear throughout its documentation and tutorial materials, in their use of concepts and terminology, and through the use of "branding" devices such as the logos provided by the W3C http://www.w3.org/2007/10/sw-logos.html I have no strong opinion on whether DCMI should continue to promote the use of community-specific abstractions based on the RDF triple/graph data model (like "description set", "description", "statement", "value surrogate" etc). I'm slightly "against" on the grounds that their use has caused confusion. But IF those abstractions are useful AND IF they can be well defined in relation to the RDF graph/triple model (i.e both conditions are true), then I would not object to that. Any solution which ignores the RDF model would not have my support.
