<AndyS> At a minimum, only need it for "<".

<AndyS> Or could relax the test - its the difference of order by (lex, type) vs (type, lex) [ordered pairs]

<AndyS> Be good to get feedback from as wide a selection of impls as possible here.

<ericP> some tests lean on the corresponding <

<AndyS> If they all do the same, no lines of code will change! because text says ...

<ericP> everything labeled with mfx:StringSimpleLiteralCmp in data/OpenWorld/sameTerm-manifest.ttl

<ericP> i'm just trying to see what the best answer to the ambiguity is

<AndyS> [[

<AndyS> The "<" operator defines the relative order of pairs of... simple literals, xsd:strings, ...

<AndyS> ]]

<AndyS> so that text applies to simple lits + xsd:string already (i.e. shows intent)

<AndyS> Not a great argument but.

<AndyS> True - there could be other readings.

ericP, joining?

<ericP> yes, beating head against wall first...

sorting tests

test progress

question: what happens when sorting a plain literal and an xsd:string literal with different lexical forms?

ARQ thinks that "alice"^^xsd:string < "bob"

and that "bob" < "charlie"^^xsd:string

<AndyS> Glitter - same

ericP: < isn't defined on those two

"""

SPARQL also fixes an order between some kinds of RDF terms that would not otherwise be ordered:

1. (Lowest) no value assigned to the variable or expression in this solution.

2. Blank nodes

3. IRIs

4. RDF literals

5. A plain literal is lower than an RDF literal with type xsd:string of the same lexical form.

The relative order of literals with language tags or typed literals with different types is undefined.

"""

<AndyS> In unextended SPARQL, < does not apply to the pair xsd:string, simple literal

ericP: that text doesn't cover this situation, as well as not covering the situation in which you compare an integer and a date
... ...so maybe we don't test for this

AndyS: We could remove 5 to loosen ordering requirements (and not test for this case)

"[en]This is in English!"^^xsd:string :-)

ericP: we could add an expository note about this

SteveH: I get the same results as Andy

<AndyS> ACTION: Eric+Andy: Collect all the testing feature URIs and put in the documentation [recorded in http://www.w3.org/2007/06/26-dawg-minutes.html#action13]

<LeeF_> PROPOSED: Approve #dawg-sort[1..10] in http://www.w3.org/2001/sw/DataAccess/tests/data-r2/sort/manifest.ttl

<LeeF_> steveH seconds

<LeeF_> resolved

<ericP> ACTION: ericP to write explanatory text saying that, like xsd:inteter and xsd:dateTime, the relative order of simple literals and xsd:strings is not defined here [recorded in http://www.w3.org/2007/06/26-dawg-minutes.html#action14]

<LeeF_> ACTION: LeeF to mark approved sorting tests (1..10) as such [recorded in http://www.w3.org/2007/06/26-dawg-minutes.html#action15]

<LeeF_> ericP and SteveH do not pass a bunch of tests in graph/ and dataset/ due to lack of implementation support

<LeeF_> http://www.w3.org/2001/sw/DataAccess/tests/data-r2/graph/

<LeeF_> http://www.w3.org/2001/sw/DataAccess/tests/data-r2/dataset/

<ericP> ACTION: ericP, AndyS to add the mf:requires labels to the manifest namespace document [recorded in http://www.w3.org/2007/06/26-dawg-minutes.html#action16]

<LeeF_> http://www.w3.org/2001/sw/DataAccess/tests/README.html

<LeeF_> ACTION: chimezie and/or ericP to try running tests in data-r2/dataset and data-r2/graph and report results by July 10 [recorded in http://www.w3.org/2007/06/26-dawg-minutes.html#action17]

test harness

<LeeF_> LeeF will follow-up with Ivan/Orri to see if they might provide a SPARQL endpoint URI -> test results service

implementation report progress

<LeeF_> ericP: xpath-testable stuff in the facets document, and stuff coded otherwise that isn't xpath testable

<LeeF_> ...the facets data (not all of it expressed in xpath) identifies everything we're testing for

<Zakim> AndyS, you wanted to ask which tests to target next

<LeeF_> http://www.w3.org/2001/sw/DataAccess/tests/data/

<LeeF_> LeeF_: Casting dir in /data/ seems empty

<LeeF_> ... we'll need CONSTRUCT tests

<LeeF_> ... we'll need DISTINCT tests

<LeeF_> ... we'll need the TypePromotion tests

<LeeF_> ... we'll need the i18n tests

<LeeF_> ericP: i pass all 3 CONSTRUCT tests

<LeeF_> adjourned.
