[tcs-lc] enumeration of relationsihp types

[Roger Hyam]

Hi James,

The primary use of the schema is to communicate between machines so the 
consuming software has to have some idea what it is going to do with a 
relationship (either as part of an assertion or as part of a concept 
definition) when it arrives. If we have 'free form' relationships then 
we lose this.

Having said this I don't imagine all implementation being able to use 
all the relationship types in the schema as it stands so there may be an 
argument for an extension mechanism. I have added it to the tracker 
(http://tracker.hyam.net) as issue 011 so we don't forget it.

Homonyms are dealt with as part of the NameObject. If a name is a later 
homonym of another name then you can add a pointer to the older name.

Could you give an example of a relationship we haven't thought of?

Hope this helps,

Roger
