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. pa On 03/12/2022 00:21, Souripriya Das wrote: > Attached a revised version of the RDFn slide deck [1] that includes > > * (slide 8) new slide titled "RDFn Semantics: Essentials, in a few > words" > * (slide 9) corrected slide titled "RDFn Semantics: Essentials > Beyond RDF" that now states that TI INTERSECT TE need not be an > empty set and shows the corrected diagram > * (slide 14) new slide titled "Enabling Explicit Naming in RDF-star, > Serializations, and SPARQL-star" > > Thanks, > Souri. > > [1] > https://lists.w3.org/Archives/Public/public-rdf-star-wg/2022Nov/att-0016/RDFn_WG_Slides.pdf
