we actually discussed the items in a different
order, to avoid having 3. "issue: fromUnionQuery"
take up the whole call again. Items 8 and 9
were not discussed.

DONE:

but this proposal didn't get a critical mass of support.

RESOLVED: to close wsdlAbstractProtocol ala
http://www.w3.org/TR/rdf-sparql-protocol/ 1.51 2005/06/06 18:35:00 ,
i.e. one interface, one operation; HTTP keywords query,

DanC summarized by observing 3 designs that seemed to be coherent
and had been developed and advocated sufficiently that we might
be able to finish them in a timely manner:

OPTIONS:
  (a) without FROM/FROM_NAMED, dataset is unconstrained; with
   FROM/FROM_NAMED, dataset is bounded from below by given references.
  (b) like (a) but FROM/FROM named completely specify the dataset
  (c) datasets have "aggregate graph" rather than background/default
   graph, and it always contains the merge of the named graphs

By "bounded from below," DanC clarified that he meant D1 >= D2 iff
	D1's background/aggregate graph has everything that D2's has,
		i.e. D1's bg graph rdf-simply-entails D2's
	and D1 has all the named graphs that D2 has; i.e.
	for every named graph (U, G) in D2, (U, G) is also in D1's named
	graphs.

KC observed that this is basically a web-social question of
constraining what publishers do.

DC observed that constraining publishers might be responsive
to comments on this part of our spec, in the interest of
interoperability at the expense of flexibility.

Polling showed significant opposition to (c); after that option
was removed, the WG was split nearly 50-50 between (a) and (c).
In the interest of time, the chair chose one of the proposals
and we

RESOLVED: to go option (a) without FROM/FROM_NAMED, dataset is
unconstrained; with FROM/FROM_NAMED, dataset is bounded from below
by given references.

indeed, this is DONE to the satisfaction of the meeting.

SH: not too happy about NaN being false. and ""@fr

But this follows from XQuery, and we didn't see sufficient reason
to not follow that precedent.

RESOLVED: to address valueTesting ala

This issue seemed to be worked out in substance to the satisfaction
of most, if not all present. In discussion of what form the question
should take, it wasn't clear that the grammar in the editor's
draft was done enough to decide on, so we made a decision
based on test materials:

the WG decision on str() and uri() is confirmed, even after review of

KC, SH volunteer to do a last-call-candidate review
JB too

> last call duration

> last call comment handling process

DanC observed that so far, comment handling has been on
a best-effort basis, led by the editors, assisted by
anybody else in the WG, and occasionally audited by DanC.
When we go to last call, it'll get more formal.

This exchange in IRC is quite apt...

5:53:36 [patH]
        Handling comments at last call, it all gets formal. Rather like
        a dance at a 17th century ball.
15:54:58 [kendall]
        Ah, but the great century for formal balls was the 18th and into
        the bow-end of the 19th. :>
15:56:02 [patH]
        Yes, Kendall, but in the 17th they were trying hard to be formal
        but there was still straw on the floor. Its more like that.
15:56:29 [kendall]
        *ah*, excellent. It's formal, but the pig is liable to wander
        through..
15:56:34 [patH]
        Quite.

Some relevant excerpts from the W3C process document:

"The following information is important to the decision to advance a
technical report and therefore MUST be publicly available:
 [...]
      * Responses that formally address issues raised by reviewers"
 -- http://www.w3.org/2004/02/Process-20040205/tr.html#transition-reqs

"3.3.3 Formally Addressing an Issue

In the context of this document, a group has formally addressed an issue
when it has sent a substantive response to the reviewer who raised the
issue. A substantive response is expected to include rationale for
decisions (e.g., a technical explanation, a pointer to charter scope, or
a pointer to a requirements document)."

DC has a WG-local process that has worked reasonably well two
or three times, and plans to use it again for DAWG:

When a comment comes in, there are a few options

(1) editor attempts to satisfy the commentor without changing
any bytes in the spec, perhaps by explaining ala "perhaps section
6.4 answers your question?"

(2) chair attempts to satisfy the commentor by quoting decisions
the WG has already made

(3) a WG member (e.g. editor) is persuaded that some bytes
in the spec should change

        (3a) editorial => editor proposes new text to the chair, copying
        the WG; chair either says "yes, that's clearly editorial; pls
        make the change and notify the commentor"
        or "no, that might not be editorial; I'll put it on the
        WG agenda" or "Fred and Jane, do you agree that's editorial?"
        
        (3b) non-editorial: for any changes to the design, e.g.
        something that's observable from a test, we'll need a WG
        decision to make the change.
