ADAPT TimeContext Definitions

Apr 5, 2016 @R. Andres Ferreyra (Unlicensed): Having assembled a long, somewhat arbitrary list of contexts, I think we can more effectively capture semantics with 2-3 attributes instead of a single DateContext attribute. See Valid Compositions table below.

Some challenges:

Not all possible compositions are "valid".
Any given "valid" composition (except perhaps for "(Actual)Create" and "(Actual)Modify)" is usable in only a subset of the TimeScope-bearing classes in ADAPT.
Should we build some kind of knowledge representation system to capture all of this?
- The proposed SPADE3 ContextItemDefinition class has the concept of "Properties" that we could use to bring along the multiple attributes of any given DateContext.
- Another possibility is to build a separate artifact to manage this, such as an ontology.
