15:37:02 <Benjamin> ivan: Should we refer to SPARQL instead of defining it ourself

Ivan Herman: Should we refer to SPARQL instead of defining it ourself

15:37:19 <Benjamin> mark: it is more conceptually related

Mark Birbeck: it is more conceptually related

15:38:52 <Benjamin> ivan: Mark, you defined a subset of sparql in the RDFa API, maybe we should use and refer to the terms of SPARQL then.

15:49:59 <Benjamin> ivan: There is a similarity between TURTLE syntax and SPARQL patterns. Now there is an emerging JSON serialization of RDF, and our JSON related query features.

15:53:15 <Benjamin> ... Nathan and I want a more generalized graph mechanism than RDF allows.

15:54:01 <Benjamin> ... these graphs may not be serializable in RDF/XML - we have to coordinate with the RDF working group

... these graphs may not be serializable in RDF/XML - we have to coordinate with the RDF working group

15:55:06 <Benjamin> ivan: A generalized graph mechanism is out of scope for the RDF Working Group, as is using blank nodes in predicates, or literals as subjects.

Ivan Herman: A generalized graph mechanism is out of scope for the RDF Working Group, as is using blank nodes in predicates, or literals as subjects.

15:56:21 <Benjamin> ivan: However, a number of RDF environments already provide such generalized graph mechanisms.

Ivan Herman: However, a number of RDF environments already provide such generalized graph mechanisms.

15:59:17 <Benjamin> ivan: Often intermediate steps in these systems use versions of graphs that are also not serializable, e.g., for supporting reasoning. When serializing the graph, the generalized graph mechanism are ignored.

Ivan Herman: Often intermediate steps in these systems use versions of graphs that are also not serializable, e.g., for supporting reasoning. When serializing the graph, the generalized graph mechanism are ignored.

16:00:11 <Benjamin> ivan: It is not a problem to let serializers be silent on generalized graph mechanisms - so that may not be a big issue.

Ivan Herman: It is not a problem to let serializers be silent on generalized graph mechanisms - so that may not be a big issue.

16:00:37 <Benjamin> ivan: Graph literals are heaviliy discussed at the moment so we should skip them
