RDF-star

Features

makes use of the "many-to-many" nature of reifiers, where multiple triples can be reified at once, and several reifiers can be related to the same triple

https://w3c.github.io/rdf-star/cg-spec/editors_draft.html#sa-mode-and-pg-mode
- are quoted triples asserted?
  - t.2023.12.01 depends on the implementation!?
    - JSON-LD-star has embedded nodes for non-assertion, annotation objects for assertion
https://w3c.github.io/rdf-star/cg-spec/editors_draft.html#the-seminal-example
- can you have multiple identical triples?
  - nope! have to use standard reification, new relationship concept
    - but don't need them anyhow if you're not asserting the triples (ie., Separate Assertion / SA) or if the thing asserted is quoted and assigned a temporal / instance info
  - Type Token Distinction

Referential Opacity
- https://www.w3.org/2021/12/rdf-star.html#ref-opacity
- https://github.com/w3c/rdf-star/issues/22
- t.2024.06.07.10 things should be opaque most of the time, since it's important for beliefs and provenance, and since you can get transparency from opacity
  - but see https://github.com/w3c/rdf-star-wg/wiki/RDF%E2%80%90star-examples-of-profiles#9-why-opaque-triples-do-not-work-for-data-integration-p-a-champin for an argument that opaque isn't sufficient, but it's possible that Charlie's sameAs is incorrect
