Natasha,

Thanks very much for your comments.

At the moment I wrote this I thought there were examples of 
collaborative efforts that are not really used, but I must admit I 
cannot come up with an example right away.

Yes, good point. I will include this maintenance criterion.

The idea was that the WG would provide support conversion in two ways:

- general support: WG note on conversion guidelines
- specific support: group of volunteers helping with the actual
   conversion of a particular ontology/vocabulary

For the latter group I was thinking off people who have actively used 
the ontology/vocabulary and in whose interest it would be to have an 
"official" RDF version. For example, we have a lot of interest in the 
Getty thesauri and would be willing to provide support in the conversion 
process. Other people have done work on converting WordNet, etc.

So, although it is not the responsibility of the WG to do the 
conversion, I expect there will be volunteers willing to provide 
(varying levels of) support.

To be corrected.

I will add these to the list.

This sentence was meant to indicate that we are focusing here on 
open-source software tools. I will make this clearer.

Yes, thanks.
