SemanticsInterOpMay2008 SessionsTrieste, May 19-23Session 1 (monday 19, 16:30-18:00, Vulcania 1)Vocabularies
Issue 1: format of master fileResolved that no format mandated for the master sourceIssue 2: format of distributd filesMatthew suggested mandating RDF/XML only, Alasdair agreed. So Resolved that distributed vocabularies MUST include an RDF/XML form, and SHOULD include a Turtle form. Sébastien suggested including warnings about pitfalls when serialising as RDF/XML.Issue 3: vocabulary versionsResolved that vocabulary namespaces will contain no version information, but resolve to the most current version of the RDF description of the vocabulary. Vocabulary maintainers SHOULD keep old RDF files available long-term.Issue 4: vocabulary maintainersResolved that vocabularies will not be maintained by a process set up by this recommendation. Vocabularies will be maintained by whichever WG or external authority 'owns' them. Rob: encourage the various interest groups to get involved and adopt the vocabularies into their processes.Issue 5: which vocabularies will be distributedResolved to include the 5 uncontroversial ones, and refer to, but don't include, the IVOA-T. Sébastien will investigate SKOSifying the Vizier vocabulary, which will act as a further implementation. Someone (can't remember who!) offered to compare the standard IAU constellation list at CDS with the simple vocabulary included in the document.Issue 6: mappingsAlasdair talked about mappings, recommending that vocabularies declare no inter-vocab mappings; such mappings are published separately; mappings declared in one direction. Thus resolved. What metadata is required in a mapping file? DC terms? This should be clarified in the document. Some discussion of how vocabularies and mappings should be developed and maintained. There are both technical and social issues to be resolved here, but they don't have to be resolved by this document's process. Norman will investigate wiki-like tools which can support a process like this. Let this go to Rec, referring to the SKOS WD, with a note at the beginning of the document explaining the situation, and that we'll produce another version when the SKOS WD goes to Rec. Is everyone happy with those?Session 2 (tuesday 20, 9:00-10:30, Vulcania 1) (swap with Theory IG) (ppt)UCDs
