testing rdf:JSON

[pfps]

How will rdf:JSON be tested?

(Put here because the test repository does not have the labels for WG discussion.)

Other than testing for literals that are lexically invalid, equality should probably be done in a SPARQL 1.2 version of the expo-equals tests from 1.0. Although, note that there are no such tests for rdf:XMLLiteral or rdf:HTML. Generally, those tests have been done in the RDF/XML and RDFa test suites, to the degree that they can.

The rdf-mt test suite has an entailment test for inconsistency in XMLLiteral terms (rdfs-entailment-test001).

The N-Quads, N-Quads, Turtle, and TriG test suites have tests that include XMLLiterals (test-subm-01), but just tests parsing.

SPARQL 1.1 has an entailment test for XMLLIteral (rdfs08).

RDF/XML has a single xml-canon test, which really tests that the RDF Literal value extracted from the XML is appropriate and does not test values.

RDFa also has some XMLLiteral tests, but I don't see any HTML Literal tests.

rdf:XMLLiteral and rdf:HTML do most of their testing (other than for values) in their respective test suites. JSON-LD also has a number of rdf:JSON tests (e.g., js01). Most tests that don't involve values or equality probably belong in the JSON-LD test suite. Other tests probably in the SPARQL test suite.

(Aside, the RDF-star project does also track tests from the RDF-tests repo, so I'd say it's worth keeping test-specific issues in that repo).

I think that there needs to be RDF tests that test the various aspects of rdf:JSON. Otherwise how can the requirement of two interoperating implementations be determined?

One kind of test would be entailment tests that show how rdf:JSON literals are processed, such as:
:a :b "1E400"^^rdf:JSON .
entails
:a :b "1E401"^^rdf:JSON .
and
:a :b "1E401"^^rdf:JSON .
does not entail
:a :b "null"^^rdf:JSON .
and
:a :b "0"^^rdf:JSON .
does not entail
:a :b "-0"^^rdf:JSON .
