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
