with Drummond Reed on  I now
see that a “Contextualized SubjectId” or “CSId” is
synonymous with SubjectRelationship as defined here .
Rather than have
two names for the same
concept, I propose we replace them both with “SubjectRelation”
(loosing the “ship” shortens things a tiny bit and lines up better
with the higgins:relation property). For symmetry I also propose
ContextRelationship with ContextRelation while we’re at it.
