TheorySemanticVocabulary < IVOA

This page is  meant to gather input on properties and possible values for describing simulations and their results. One of the uses of this list is forming a proposal for additions to the UCDs and Semantic  Vocabulary lists of the UCDs working group.

This list was started during a meeting of the theory interest group on Tue May 16, by simply writing down terms that were used in a discussion about how to describe simulations. We added a little structure as a first separation for what should end up as UCD or as a word in the "semantic vocabulary".

The deadline of June 16 set at the interop meeting has passed and a core group has started working on collecting and organising the list into a Note for the Semantics working group.

---++ Links
Starting June 19 2006 we will go through the exercise of further classification and, importantly, finding out which concepts and words already exist in the lists. To this end a few useful links are gathered here
