This page collects specification issues as well as proposals for extensions DALI 1.0.

---++ vocab URL

Section 2.3 "Examples: DALI-examples" proposes to use ivo://ivoa.net/std/DALI#examples as the default vocabulary URL. That is unfortunate as the actual terms in RDFa are generated through concatenation, such that the terms that would actually end up in the StandardsRegExt document (not that they're actually there) would look like "examplesname", "examplescapability", etc.

Possible solutions:

(1) We could keep the notion that we're using StandardsRegExt records to keep the examples vocabulary. In that case we would IMHO have a document separate from DALI's, which would mean we should write an erratum saying the vocab URL should be ivo://ivoa.net/std/DALI-examples#. This is (essentially) what's in the TAP Implementation Notes right now.

(2) After the (positive) datalink experience with RDF-enabled vocabularies and because there's no (known) code using this anyway so far, my personal take is that we shouldn't use StandardsRegExt for that in the first place. Vocab URIs, if they resolve at all, should resolve to something that RDF tools can do something with, and hence I'd say we should write an erratum saying the default vocab URI would be http://www.ivoa.net/rdf/examples (which is in parallel to what we have in datalink now).

As we don't really expect our tools to evaluate vocab, all this is IMHO less dramatic than it sounds. -- IVOA.MarkusDemleitner - 2015-05-11
