The RM has no mention of Data Model things like occurrences, scope, names,
variants, etc... only assertions and sub-graphs of the assertion graph that
are targets for reification in the n-ary relationship model: t-topics,
c-topics, r-topics, x-topics, a-topics.
But if I'm implementing the DM using the new RM, do I have to do the
following things????
1) reify every name and occurrence resourceData, they become x-topics in
assertions for relating <topic, name>, <name, variant>, and <topic,
occurrence>. But reifying literal strings gives me a new reification
operator "subjectLiteral", along with subjectLocator, subjectIndicator?
2) does DM scope then become the total of all the other assertions (those
not included in the DM) made about these other assertions: a) <topic,name>,
b) <name, variant>, c) <topic, occurrence>, d) <a-topic, c-topic, c-topic,
...)
Just curious... jason
