David, I created ISSUE-222 to keep track of your feedback: https://github.com/json-ld/json-ld.org/issues/222 Cheers, Markus -- Markus Lanthaler @markuslanthaler > -----Original Message----- > From: David Booth [mailto:david@dbooth.org] > Sent: Wednesday, February 27, 2013 5:38 AM > To: public-rdf-comments@w3.org > Subject: JSON-LD should be an RDF syntax > > These are comments on > https://dvcs.w3.org/hg/json-ld/raw-file/default/spec/latest/json-ld- > syntax/index.html#relationship-to-rdf > > 1. JSON-LD should be an RDF syntax, just as Turtle is an RDF syntax. > This means: (a) it should define the *same* data model as RDF -- not a > superset; and (b) it should have the same semantics as RDF serialized > in > any other syntax. > > It does not make sense for the W3C to define splinter the RDF market by > defining a competing data model that is so similar to RDF and fills the > same needs. Section C 'Relationship to RDF' makes clear that JSON-LD > defines a *different* graph model than RDF: "The RDF data model, as > outlined in [RDF-CONCEPTS], is an abstract syntax for representing a > directed graph of information. It is a subset of JSON-LD's data model". > > If the long-term plan for RDF is that it will eventually embrace the > additional features of JSON-LD (such as blank nodes as graph names, > blank nodes as properties) then the RDF specification itself (and the > SPARQL specification?) should be changed NOW to be consistent with > JSON-LD,. > > 2. A JSON serialization of RDF should not require IRIs to be > dereferenceable -- even with a "SHOULD" requirement as currently > stated: > [[ > IRIs used within a JSON-LD graph should return a Linked Data document > describing the resource denoted by that IRI when being dereferenced. > ]] > > Fundamentally this specification should be defining JSON-RDF -- not > JSON-LD. There are many RDF applications that are not Linked Data > applications but would nonetheless benefit from a JSON serialization of > RDF. > > However, it would be good to define JSON-LD on *top* of JSON-RDF, once > JSON-RDF is defined. > > David
