Relationships

For GIG discussion:

       Would a Unit Type have a relationship to another Unit Type? Ie – Unit Type ‘Employees’ could be related to Unit Type ‘Persons’?

Perhaps a broader/narrower or super/sub-class relationship?

 

       Would a Unit Type have a relationship to a Concept?

As per previous comments on the wiki by Dan : (comment 1 Feb 2013)

“It looks like Object Type (Unit Type) should replace Populati on as a role for a Concept…”
