Support for RDF-star & JSON-LD-star

[damooo]

Namaste.

Thanks for your great work.

RDF-star and SPARQL-star standards addresses the problem of annotating arcs in an RDF Graph by extending the RDF data model to allow for triples to be used as the subject or object of another RDF triple. RDF* is the name of the original work which is described in Olaf Hartig’s blog entry.
Example:

<< :john foaf:name "John Smith" >> dct:source <http://example/directory> .

The part << :john foaf:name "John Smith" >> is an embedded triple and refers to the triple with subject :john, property foaf:name and object "John Smith".

Though techniques like reification, are used previously to say something about a triple, RDF* approach is more straight forward. And also lays foundation for data integration from property-graph stores too.

RDF* is now de-facto standard addressing this pressing need to say about triples. It has companion standards like SPARQL*, TURTLE*, etc. They are already supported by most of major triple stores like Apache-jena, AllegroGraph, etc, out of the box.

JSON-LD-star is a jsonld community group draft standard, edited by @gkellogg himself, which minerlly extends JSON-LD to support serializationof RDF* graphs. It will be of great consequence in it's intended purpose of referring a triple, and thus also in integrating property graph stores data in lossless way.

It would be very helpful if json-gold add suport for json-ld-star.

Thanks again for your great work.

@damooo, thanks for raising the issue. I can confirm RDF-star and JSON-LD-star standards are on the roadmap. However, we can't commit to a specific timeframe.

Also, JSON-LD-star is still a work in progress, and it may still change some.
