different kinds of occurrences (Re: "Multi-Edge Support in RDFn" slides)

Hi Souri,


Another remark about the presentation :


in slides 6, you point out that RDF-star requires an extra predicate to 
link between the triple and the IDs of its occurrences (:occursAs in 
your example), while in RDFn there is no need for such an extra predicate.


I would argue that this extra predicate is actually desirable:


multiple "occurrences" of the same triple can be used to model a large 
range of /different/ things. E.q.


     # the same triple being mentionned in different sources:


     << :alice :workingFor :acme >> :mention :m1, :m2.
     :m1 :in <file1.nt> ; :line 12.
     :m2 :in <file2.nt> ; :lin 34.


     # the same claim being made by different people:


     << :alice :workingFor :acme >> :claim :c1, :c2.
     :c1 :by :alice ; :at ""2022-11-10T12:34:56Z"^^xsd:dateTimestamp.
     :c2 :by :charlie ; :at ""2022-12-09T01:23:45Z"^^xsd:dateTimestamp.


     # the same situation happening at different time:


     << :alice :workingFor :acme >> :situation :s1, :s2.
     :s1 :startDate "2020-01-02"^^xsd:date ; :endDate 
"2021-03-04"^^xsd:date.
     :s2 :startDate "2022-05-06"^^xsd:date.



so the extra predicate is important to explicitly indicate what "kind" 
of occurrence we are talking about.
