ATTENDEES: Wendy, Jay, Dan G.

Discussion of collection realizations:

• Statistical Classification is the same as a CodeList
• Not necessarily in practice
• Statistical Classification needs to be mutually exclusive and exhaustive as well as managed
• Extension of Statistical Classification from CodeList would support use of Statistical Classification as enumerated value domain
• The difference should be between managed and unmanaged, mutually exclusive and exhausted are boolean features.
• Add spatial relations for use as specialized classes of base relations
• If you inherit from CodeList you can use all of these
• The distinction between category set and codelist is having designations (signifier associated with signified)
• A signifier is currently a string in a Code but could be an image or sound etc.
• Dig deeper into designation down the road if we want to pull things together in this way.

Jay and Dan G. will walk through the realizations next week. Will also have a discussion during TC meeting period this week as there is no TC meeting

Wendy will review what extending Statistical Classification from ColeList would look like. Also explore implication of extending Unit Type, Universe, Population from Concept
