Hello all

A side question : identification of creator, contributor, publisher, date
etc of vocabularies is a precious information which can (should) be found
in formal vocabulary metadata under as dc:creator etc.
The tools are not always giving a consistent view of this information
between the RDF and HTML files.

Examples in Neologism but I remember other tools having similar issues but
can't figure which ones just now (LODE maybe)

The URIs for agents are created in the RDF in the namespace of the
vocabulary itself, derived from the name apparently (automatically by the
tool?). This entails that the same agent appears for different vocabularies
under different URIs, making difficult identification of the agent across
different vocabularies, unles owl:sameAs are declared somewhere (but they
are not in the vocabulary itself at least). I just had an exchange about it
with Michael Hausenblas who in the RDF source of various DERI vocabularies
appears as
... etc. many more.
OTOH the html documentation of all vocabularies points at
http://sw-app.org/about.html. And Michael claims his "canonical" URI is
http://sw-app.org/mic.xhtml#i as declared in the meta of the above page <
meta rel="dc:creator" resource="http://sw-app.org/mic.xhtml#i" />

Simple, isn't it? :)

It would be cool to have the edition tool allow a consistent use of a
"canonical URI" of an agent in both RDF and HTML renditions, and across
vocabularies. Does not seem rocket science :)

Samely, the date of modification of the vocabulary seems OK in the HTML,
but in the RDF dc:modified value it is the current date.

Minor things? Not really. Quality metadata are critical for vocabulary
trust, reuse, integration etc. Vocabularies are social objects :)
