SPARQL WG Agenda - Tues. Nov. 17, 2009

Busy meeting tomorrow. I'm planning to limit discussion on topics other 
than the ones that have had discussion on the mailing list, so if you 
are concerned about any of the issues that I am proposing to resolve or 
take a straw poll on, please raise them immediately.

* Anything to report from the Entailment TF telecon?
* Let's resolve the following issues from without 
further discussion
** PROPOSED: Resolve ISSUE-11 by noting that it's invalid to project 
variables/functions on variables that are not included in the GROUP BY 
clause and also nothing that what this means in practice depends on ISSUE-41
** PROPOSED: Asterisk is a valid argument to COUNT, but not to other 
aggregate functions, and not to custom aggregates
** PROPOSED: A projected solution that contains a type error results in 
that solution being discarded from the solution set
** PROPOSED: SPARQL 1.1 does not inlude any subqueries other than 
sub-selects in graph patterns, noting that the question of an EXISTS 
FILTER form is still pending
* Straw polls to decide issues without strong feelings - minimal 
discussion allowed
and others...)
*** See
** Do projected expressions require an alias?
*** See
*** See
** Commas in select list?
*** Note that SteveH has withdrawn support for this
*** Choices are "commas required for expressions", "brackets required 
for expressions", "both allowed"
* Aggregates and mixed datatypes
** MIN/MAX over mixed datatypes and errors
** SUM/AVG over mixed datatypes and errors
** See
** Also see
* Scope of alias variables
** See
* Do aggregate functions need to be set off syntactically?
** Touches on ISSUE-15 and also whether or not all aggregate functions 
can accept a DISTINCT modifier
* Next time - update issues? service description? http update? protocol?
