FAIR vocabularies

Dear Markus,

Many thanks for your prompt answer. I had missed the fact that there is 
a licence on the IVOA vocabularies.

The licensing question was evident, but to find whether there are other 
issues one would need to make a detailed assessment. My understanding is 
that the criteria to establish that a vocabulary is FAIR are not really 
agreed upon at this time, so I guess that the RFC should go on with its 
own schedule. If there are people interested in discussing the rules 
which are being discussed in different venues, maybe we can have a small 
sub-group to have a look together?

Cheers

Francoise
