Subject: Re: [office-metadata] Fwd: Public Comment on a DCMI vocabulary ofdomain and range classes
These are interesting news. Thanks for the forwarding, Bruce. I guess you have in mind to give in the spec a suggestion of a set of RDF vocabularies, which are currently frequently used. This might help later implementations, although I assume the mentioning of vocabularies can only be informative in the spec as I see no way how to make the usage of a RDF vocabulary mandatory in an ODF application.
