2. issue: sort

http://www.w3.org/2001/sw/DataAccess/issues#sort

The WG discussed whether SORT design and inclusion in the language will 
continue or not. Poll showed interest to pursue the design further and 
to keep sorting as an objective for DAWG.

Kendall explicitly noted that new objectives are useful at this point 
even if we don't do them; there's likely to be another charter, 
eventually. they seem good input to that.

As AndyS has suggested a design in

http://www.w3.org/2001/sw/DataAccess/rq23/#solutionsResults

so the following 2 action items were assigned to review that design

ACTION PatH: review sort design in 2 weeks
ACTION Kevin: review sort design at earliest convenience




3. optional test for with background inference

JosD had had an action item to
ACTION JosD: Jos to propose an optional test based on ACTION op:dateTime 
triple

which is considered DONE in
http://lists.w3.org/Archives/Public/public-rdf-dawg/2005JanMar/0361.html

DanC was expecting to see was expecting the inferred triple (whose 
predicate is op:dateTime-greater-than ) in the input data and took an 
action item

ACTION DanC: follow up re optional test based on op:dateTime triple



4. Test suite maintenance

JosD had had an action item to
ACTION JosD: propose a test based on dawg-triple-pattern-002 with a . in 
a qname

which is considered DONE in
http://lists.w3.org/Archives/Public/public-rdf-dawg/2005JanMar/0360.html

The WG observed the . in a qname is only present in the input data, not 
in the query language itself which we should be testing.

SteveH noted there's a test with dot in the query language expression in
http://www.w3.org/2001/sw/DataAccess/tests/#syntax-004

DaveB noted turtle definitions don't include dots in qnames and thus got 
an action item to

ACTION DaveB: consider dots in qnames, report on impact on turtle

Other action items continued

ACTION EricP: to pair with SteveH on making the HTML test results page 
(continued)
ACTION SteveH: to to revise test manifest w.r.t. "background" and named 
graphs (continued)
ACTION DaveB: to to propose source test to approve (continued)
ACTION AndyS: to add the above graph test cases (analagous to 
valueTesting test cases) (continued - don't expect quick delivery)



(moved to agenda item 9 for the sake of time)

9. requirements review before last call

WG discussed how to publish the test cases document. SteveH volunteered 
to make it into a NOTE

ACTION SteveH: prepare test cases for publication as WG Note (no 
deadline/urgency)

WG discussed publishing of the updated Use Cases and Requirements 
document in
http://www.w3.org/2001/sw/DataAccess/UseCases

Section 2.18 that motivates WSDL was deemed to require some rewording 
both in title and in contents. The wording now leads into thinking the 
wsdl interface is mostly for inserting and not for querying.

ACTION Kendall: To rewrite 2.18: change the title, don't motivate 
"update", spell "WSDL" correctly. :>

WG decided to publish updated documents

ACTION KC, AFS, EP: publish usecases 1.148 + revision to 2.18 by KC, 
reviewed by AFS, plus editorial fixups by KC, ok'd by EricP

The remaining time WG spent discussing how members felt about the 
inclusion of the new features (such as disjunction, sorting, casting, 
update, xml serialization and wsdl) into the WG work.

Some features were considered worth the effort with the conscious risk 
of missing our known schedule.

The philosophy of 'better right than fast' was appealing to many members 
while acknowledging the contradiction with the ability to deliver in time.


Adjourned at 16:09 UTC.

Next meeting: 29-March-2005 at 14:30 UTC.

!!! Please be careful with the timing as Europe is moving into Summer 
time next Sunday !!!

Scribe for next meeting: N.N. (JanneS realized after the teleconf he 
will be sitting in a car during next teleconf without being able to take 
notes. No beer for Janne that is.)
