The WG chair (APM) and vice-chair (SD) will not be present at the EXEC as they already had flights booked before the formal invitation was sent.

What we hope to accomplish at this InterOp:

The major subject of discussion will be "Vocabularies in the VO". The WD has been discussed at length, but there are still few open issues to settle down. The most important are

• cross-matching of different vocabularies
• use cases (VOEvent, Registry, ...)
• if and how to go for an IVOA vocabulary

During the InterOp we hope to clarify these (and other) points, and then promote the document to the PR stage.

But here there is a "procedural" problem: the adopted format for the IVOA vocabularies is SKOS, now at the stage of W3C Working Draft. SKOS will not become a W3C REC until (hopefully) the end of this year. The question then is: can the IVOA (through its Semantics WG) have documents based on this W3C format that are in a higher stage than the W3C document describing the format?

We ask the advise of the EXEC on this point.
