Re: OWL-Time - questions on Turtle file

Dear all,

2. There are no "rdfs:isDefinedBy" statements. More specifically, I
was expecting to see "rdfs:isDefinedBy <http://www.w3.org/2006/time>
<http://www.w3.org/2006/time>" for each class and property in the
ontology. Aren't they needed (or recommended) to link back classes and
properties back to the ontology?

+0. There is no recommendation of using rdfs:isDefinedBy for each class and
property. IMHO, knowing that all the ontologies used in the vocab are
dereferenceable par their URIs, I would not see any need to add that extra
triples.


+1 in favour of rdfs:isDefinedBy axioms.

My arguments are :

 - this is in the set of Metadata Recommendations For Linked Open Data
Vocabularies, promoted by the Linked Open Vocabulary website [1] . See
section "Vocabulary Elements (Classes and Properties)"
- This is consistent with the practice applied in most of the vocabularies
published on the W3C website.
- This practice will also be applied in the ontologies published by the SSN
sub-group. There should be some consitency at least within the SDW group.

Kind regards,
Maxime
