Regrets for missing today's telco
All my votes are in the proposals page, regarding the agenda issues
issue 141: I would prefer to keep the current design (sh:class / sh:datatype), if this is not possible, I would favor 3cthe behavior of 3a is non-deterministic and depends on data on the data graphe.g. ex:A ex:p "asdf"^^ex:myDTmight or might not pass validation depending on if ex:myDT a rdfs:Literal exists in the data graphand here we also have the inference issue for subclasses of rdfs:Literal which complicates the constrainte.g. one might have ex:myDT a ex:Literal in the data graph and ex:Literal rdfs:subClassOf rdfs:Literal somewhere else
3b cannot express non-xsd datatypes which, imho is out of the question
The behavior of 3c is consistent and depends only on shape definitionsthe equivalent shapes definition would beex:S sh:property [  sh:predicate ex:p  sh:type ex:myDT  sh:nodeKind sh:Literal]
3c needs 2 constraints (sh:type / sh:nodeKind) but so does the existing design (sh:class / sh:datatype) we cannot simplify definitions without loosing something
issue 133: I would favor my proposal of courseI also have a draft revision ready on a separate branch if accepted

Regarding the draft publicationI think the resolution of issue 133 needs to be integrated in the spec before publicationwe also need to discuss where to position the current section 3 (shapes & validation) or how this needs to changeif sections 1-3 become consistent and flow well, the rest of the spec will be easy to manage

Here is the agenda for tomorrow. FYI, I
put ISSUE-133 on it as a reference for a syntax related discussion although
it's clear that there are several related issues.
