[tcs-lc] Relationships

Here's are some naive questions that came up when I looked a little 
deeper at tcs and I couldn't see answers on the wiki in the Relationship 
topics. If there is an answer in an archive someplace, just point me at 
it, since I obviously have not been paying attention from the beginning...

The RelationshipAssertion objects are statements about something in the 
literature or contributions to the dataset, not something about logic, 
right? In particular there is nothing wrong with a concept pair having a 
RelationshipAssertion of type "is congruent to" and the same pair having 
another of type "is not congruent to" or one of type "includes" and 
another "excludes". If this is right, is there an expectation about 
what, if any, formal logic processing can be done on 
RelationshipAssertions? Is there an external ontology that prescribes an 
algebra on the enumeration allowed to RelationshipType?

What about the corresponding questions for Relationships on Concepts? 
[They must(?) be the same answers, since both have datatype 
RelationshipType]

Is there an expected connection between Relationships on a Concept and 
the RelationshipAssertions on the DataSet containing the Concept?

Thanks
Bob
