   <ericP> kendallclark, what is "ACTION: take up new issue concatenated
   nestedOptional" ???

   <kendallclark> a new issue i decided to open the meeting before the
   June break, which I cannot at this moment describe w/out consulting
   the meeting minutes from that meeting

   I think that "'II'^^roman:numeral = 2" has the same behavoir if backed
   by either "sop:value-compare(A,B) == -1" or "op:numeric-less-than(A,
   B)"

   <AndyS> "'II'^^roman:numeral = 2" is error if Roman numerals are
   unknown

   A = B RDF termRDF termRDFterm-equal(A, B)

   A = B RDF term RDF term RDFterm-equal(A, B)

   <kendallclark> Does anyone have a proposal for leading us out of this?
   It's starting to seem a bit like a morass...

   <patH> if I followed it, this seems to work

   <AndyS> I believe sop:value-comapre does it - I'm willing to flesh it
   out.

   <AndyS> It obeys the "every problem needs an extra level of
   indirection" maxim

   <kendallclark> :)

   <patH> whoops, that was a reference to andys mesage of a few days ago.

   number = number

   date = date

   string = string

   --------------------

   IRI = IRI

   bNode = bNode

   <fred> literal = literal: true or error

   <fred> iri = iri: true or false

   <fred> bnode = bnode: true or false

   <fred> allother cells always false

   2=3

   <AndyS> Yes, Fred - that's the table I was thing of.

   <AndyS> bNode = literal (not bNode in query) may be valid

   <AndyS> Separate sameLiteral operator.

   <AndyS> if we want a syntactic comparision

   <AndyS> "(x,y)"^^:geo

   <AndyS> If you want help with this, do ask - I'm the one keen to have
   this extensibility so I feel responsible here.

   <kendallclark> ACTION: EricP to redraft section 11 to support
   extensible datatypes [recorded in
   [18]http://www.w3.org/2006/08/08-dawg-minutes.html#action08]

   <AndyS> sop:vaue-compare should return symbols for LE, GT, EQ and NE
   (or error)

DAWG Formal Semantics

   <SteveH> ok, I dont have anything to add to format sem. anyway

   <kendallclark> I've also heard problems re: DISTINCT because the spec
   doesn't really define identity sufficiently rigorously...

   <AndyS> DISTINCT does not mean identity because it's separated from
   the entailment by the algebra.

   <AndyS> It is systems that onlt answer BGPs that could do that - in
   general, there is no connection there.

   <kendallclark> distinct requires some notion of identity, separated
   from entailment, it seems to me

   <AndyS> It sort of has - it's term uniqueness.

   i am utterly convinced that one of PatH and FredZ may be right

   <kendallclark> So we're 1 minute past our expire time :)

   <AndyS> Fred -- I think the practical outcome is BGP's need a DISTINCT
   applied. That's easily doable.
