Hi Ghislain,

Sorry for not being clear enough. To the best of my understanding (and 
by trying myself) you cannot simply submit your ontology to LOV and it 
will be listed there. The LOV team will, for instance, ask you to align 
your ontology to other ontologies. This may turn out to be difficult for 
various reasons. For example,  for legal reasons companies that develop 
ontologies sometimes do not want to have relations to other ontologies 
in their own ontology especially not to ontologies developed with an 
unknown maintenance model. Many ontologies were developed by students as 
part of their dissertation or projects and are not maintained anymore. 
While this is often no issue for us as a research community, it causes 
problems for the industry. Some industry and government branches, for 
instance, are only allowed to use technologies and specifications that 
have been standardized before. Similarly, if you develop an atomic 
ontology design pattern, you may not want to align it. Best practice is 
always context dependent.

My main issue with such an 'edited' repository with a small set of gate 
keepers is that the Web and the Linked Data cloud follow the AAA(AA) 
slogan, i.e., "Anyone can say Anything about Any topic (Anywhere and at 
Any time)". For instance, there are datasets on the Linked Data cloud 
that contain errors, are following very diverse modeling styles, and so 
forth. Ideally, an open vocabulary/ontology repository would only 
control for spam and so forth, but not for the style or engineering 
philosophy of the submitted ontologies. Don't get me wrong, I would love 
to have more ontologies submitted to LOV and use LOV frequently, but I 
cannot submit some of the ontologies in which I was involved for the 
reasons mentioned above.
