I have problems in understanding the whole concept of "quoted". Is this the right moment in time to express it or did I just loose the magic moment?

15:17:06 [Fabio]
olaf, andy, ok, I have a very clear idea of what are quoted triples and how they came into being. They used to be called "embedded" up until July. I simply fear the concept of "quoting" can be misleading and imprecise and not totally useful.

15:20:03 [AndyS]
AndyS: highlight "section 2" box in some way as the entry point section
15:20:57 [thomas]
(someone is typing a lot which makes listening to other audio quite hard)
15:21:08 [AndyS]
pchampin: may do SVG - need manual maintenance

gkellogg: Diagram adequate - extra text can be added
15:25:11 [AndyS]
... odd that "section 2" box does not have a title
15:26:35 [gatemezing]
+1 to add a title for "section 2"
15:26:43 [AndyS]
pchampin: will merge, and continue to refine diagram.

agendum 4 -- PR #209: New section about selective referential transparency -- taken up [from agendabot]
15:29:28 [AndyS]
olaf: context - quoted triples are referentially opaque - they are like literals.
15:30:08 [AndyS]
... vocabulary for declaring that a quoted triple can be treated as referentially transparent
15:30:49 [AndyS]
... if using an entitlement regime, can derive other nested triples
15:30:51 [pchampin]
q+
15:32:37 [AndyS]
pchampin: another way to look at it is if a property holds, that property holds for all ref transparent nest triples from the original quoted triple

15:35:48 [AndyS]

pchampin: to go between 6.3 and 6.4
15:37:54 [AndyS]
olaf: can go in section 7
15:38:45 [AndyS]
pchampin: so sec 7 introduces an entailment regime
15:39:01 [pchampin]
q?
15:39:35 [AndyS]
olaf: 6.4.6 can continue to exist for example then refer to sec 7.
15:39:44 [AndyS]
pchampin: makes sense
15:41:00 [AndyS]
... needs some work for this semantic extension
15:42:21 [thomas_]

AndyS: the Conformance section is the place that says "this is RDF-star"
15:48:29 [pchampin]
... if anyone claims to support RDF-star, this is where they should look
15:49:00 [pchampin]
... currently, system claiming to support RDF-star have very different notions of RDF-star
15:49:33 [pchampin]
... following the normative text may still lead to different implementations
15:50:52 [gkellogg]
q+
15:51:16 [pchampin]
... This is not to say that all implementations must pass the whole test suite.
15:51:33 [pchampin]
ack gkellogg
15:52:15 [AndyS]
gkellogg: specification makes normative statement and test suite tests the normative statements.
15:52:24 [gkellogg]
"Implementers can partially check their level of conformance to this specification by successfully passing the test cases of the JSON-LD test suite. Note, however, that passing all the tests in the test suite does not imply complete conformance to this specification. It only implies that the implementation conforms to aspects tested by the test suite."
15:52:26 [AndyS]
... some normative statements are hard to test
15:52:32 [AndyS]
.. JSON-LD example
15:52:34 [pchampin]

15:52:42 [AndyS]
... JSON-LD example

... conformance to a CG note and a proper WG will provide conformance to changes it makes e.g. to Turtle
15:54:05 [AndyS]
... we have tests for TTL, NT (etc), SPARQL (syntax and eval) and semantics
15:54:12 [thomas_]
+1 to gkellogg
15:54:31 [AndyS]
... may be highlight semantics in the conformance section.
15:55:40 [AndyS]

15:56:01 [AndyS]

scribe+
15:56:42 [pchampin]
AndyS: if you implemented the syntax for Turtle,
15:56:48 [pchampin]
... would there be any more work to be compliant?
15:57:25 [pchampin]
... that would be the practical approach of many implementers
15:58:16 [AndyS]
pchampin: have a python script to test implementation using SPARQL-star to test
15:58:44 [AndyS]

present-
16:01:24 [AndyS]
olaf: what consequences of semantics does this have?
16:02:02 [AndyS]
pchampin: e.g. rdflib - has D-entailment on literals. Triple stores != exactly the triple retrieved
16:02:19 [AndyS]
(rdflib is not the only system to do that)
16:03:00 [pchampin]
q?
16:03:09 [AndyS]
... tests are tagged with an entailment regime. Some are OWL (uses owl:sameAs), some D-entailment.
16:03:52 [AndyS]
... conclusion: we need something though still unclear what.
