Making our RDF interfaces/classes a php-fig standard? #92

Open k00ni opened 7 years ago

k00ni commented 7 years ago

@white-gecko: I would like to propose major Saft/Rdf interfaces to php-fig to see, if we can set a standard here, about how to model RDF triples, statements and quads.

It would be about:

Maybe adding further interfaces, like StatementIterator, or even example implementations?

Reason: I talked with the hardf, EasyRdf and ARC2 developers and i would like to suggest a common ground for future development. A contract how to describe RDF would be a good start.

What you think?

white-gecko commented 7 years ago

Cool idea, but I think for this we should be able to tell, that our interfaces are actually of use. So we need some evaluation resp. real applications using it.

k00ni commented 7 years ago

Main argument would be to support/enable interoperability of different RDF implementations like EasyRdf, ARC2, hardf or even Redland. All use different formats, some simple arrays, some class-based.

I started with a basic file: https://github.com/SaftIng/fig-standards/blob/psr-rdf/proposed/rdf/rdf.md

Link to a discussion about hardf supporting this standard too: https://github.com/pietercolpaert/hardf/issues/14

k00ni commented 7 years ago

I proposed my current working draft on the PHP-FIG mailing list: https://groups.google.com/forum/#!topic/php-fig/Z1dds-mBRrE

Current state of interfaces:

For each interface, except Node, an example implementation is available. Related code is located in this repository: https://github.com/SaftIng/PsrRdf

I started a discussion with the maintainers of

with regards to support standardized RDF interfaces. With hardf this makes all major RDF libraries.

EDIT: Added hardf Link.

@k00ni thanks for championing this work for so long! I'm sorry to see it seems to have stalled (re: https://github.com/php-fig/fig-standards/pull/958).

FWIW, there may be some opportunity to revisit this under a different banner--but with the same goals. Several of the JavaScript RDF implementers formed the RDF.js Community Group at the W3C: https://www.w3.org/community/rdfjs/ They're working now to revitalize the community by combining code efforts, and working toward revising/publishing the Interface Specification: RDF Representation (which is currently focused on JavaScript...obviously :wink:).

It might be worth working with that community to reignite your efforts for a common interface across the PHP libraries. Bonus points (for everyone!) if these mostly match across languages too! 😄

At any rate, just wanted to thank you for your efforts.

Cheers! 🎩
