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. Please add concepts, possible values and descriptions.

In general the main item is the property (UCD), the secondary items possible values (vocabulary), but there are exceptions. Later this week we'll go through the exercise of further classification and, importantly, finding out which concepts and words already exist in the lists.
