</font><br class="">
<font face="Times New Roman, Times, serif" class="">Thanks for summarising
this issue.</font><br class="">
<font face="Times New Roman, Times, serif" class="">There is also a need to
discover more easily where to find the various vocabularies
proposed by the Ivoa .</font><br class="">
<font face="Times New Roman, Times, serif" class="">I would appreciate to
have a link from the IVOA document repository page directly , to a
IVOA Vocabulary page like what we have for XML schemata, for
instance.<br class="">
</font><br class="">
<font face="Times New Roman, Times, serif" class="">Various vocabularies
already exist , in various formats and are used in DAL( datalink,
RDF, html), Registry (VOResource litterals, CSV), Theory ( theory</font><font face="Times New Roman, Times, serif" class=""><font face="Times New Roman,
Times, serif" class=""> vocabulary</font> RDF/SKOS )</font><br class="">
<font face="Times New Roman, Times, serif" class="">So this page would
actually redistribute the link access to the corresponding
locations .</font><br class="">
<font face="Times New Roman, Times, serif" class="">Each of these
vocabularies should be maintained in close contact to their WG and
users , and I see the role of Semantics more as a coordinator and
curator for the long term. <br class="">
</font><br class="">
<font face="Times New Roman, Times, serif" class="">How to organize the

<a href="http://ivoa.net/rdf" class="">ivoa.net/rdf</a> <font face="Times New Roman, Times, serif" class="">does not
mean every file in this directory should be in rdf format but this
is somewhat misleading.<br class="">
In order to allow to gather all representation formats for some
particular vocabulary, I would prefer to have one branch for each
vocabulary and the various formats below like : </font><br class="">
<a href="http://ivoa.net/vocabularies/datalink/rdf/datalink-1.0-20151107.rdf" class="">ivoa.net/vocabularies/datalink/rdf/datalink-1.0-20151107.rdf</a><br class="">

etc...<br class="">
and the same for registry vocabularies if needed. <br class="">
E<font face="Times New Roman, Times, serif" class="">ach of them could be
redirected to another site as <a href="http://purl.obspm.fr" class="">purl.obspm.fr</a> or anyother.</font><br class="">
<font face="Times New Roman, Times, serif" class=""><br class="">
If the curator of the vocabulary is close enough to the users ,
this should work, or am I overlooking some issue here?<br class="">

<pre wrap="" class="">Dear Semantics,
Dear Theory,
(IVOADoc in CC)
during the session this Tuesday, in the "SKOS in VO THeory" talk, it
was proposed a change for the vocabulary for Theory VO with patterns
pointing to
<a class="moz-txt-link-freetext" href="http://purl.ivoa.net/ConceptName">http://purl.ivoa.net/ConceptName</a>
Now (apart from DNS aspects that can be managed on the DNS+IVOADoc
side - that's why IVOADoc is in CC), <a href="http://ivoa.net" class="">ivoa.net</a> has already a branch
<a class="moz-txt-link-freetext" href="http://www.ivoa.net/rdf/">http://www.ivoa.net/rdf/</a>
that is meant to store vocabularies (Datalink one is already there).
Also, the theory vocabulary will actually physically be in Paris, i.e.
<a href="http://purl.ivoa.net" class="">purl.ivoa.net</a> will simply redirect to it.
This email is to try to understand exactly how we can make this things
work together, namely:
- the <a href="http://purl.ivoa.net" class="">purl.ivoa.net</a> and its redirection to Paris (but possibly it
should survive in <a href="http://ivoa.net" class="">ivoa.net</a> and be used by other parties)
- the relationship between <a href="http://purl.ivoa.net" class="">purl.ivoa.net</a> and <a class="moz-txt-link-abbreviated" href="http://www.ivoa.net/rdf">www.ivoa.net/rdf</a>
Ideas, comments, .... are welcome, so that we can also start thinking
of DNS changes in Trieste (hosting the <a href="http://ivoa.net" class="">IVOA.net</a> domain and related
DNS) and maybe in IUCAA (where the web part of the <a href="http://ivoa.net" class="">ivoa.net</a> is
physically located.
I can take care of connecting with IVOADoc and <a href="http://ivoa.net" class="">ivoa.net</a> sysadmins for
the technical part.
Cheers,
Marco
