ISSUE-29

mhausenblas: my intention is to have no pending issue

<cygri> ISSUE-29?

<trackbot> ISSUE-29 -- Require blank node and IRI identifier expressions to produce strings -- pending review

<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/29

<mhausenblas> ISSUE-29?

<trackbot> ISSUE-29 -- Require blank node and IRI identifier expressions to produce strings -- pending review

<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/29

mhausenblas: people from rdb2rdf and rdf wgs: please advise

<Souri> seems unrelated

@@: not sure why it's related to the rdf wg

mhausenblas: it's because it's related to blank nodes

cygri: it's about literals and strings

<dmcneil> +q

cygri: so I don't see the relation with bnodes

<Souri> +1 to Richard (Issue-29 has no relation at all to RDF 1.1 string literal)

Souri: looked at it a bit
... agree with richard

mhausenblas: my bad, I mixed it up with issue 29

<mhausenblas> ISSUE-9

<cygri> ISSUE-9?

<trackbot> ISSUE-9 -- Generate Blank Nodes for duplicate tuples -- postponed

<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/9

mhausenblas: wanted to speak about ISSUE-9

<ericP> cygri, (aside: does 29 lean on SPARQL BNode constructors? http://www.w3.org/TR/2011/WD-sparql11-query-20110512/#func-bnode)

<dmcneil> -q

<ericP> betehess: iirc, we had two solutions for the DM

<ericP> ... it was ok in the algorithm to define bnodes

<ericP> ... it wasn't clear how to do it in the datalog rules

<ericP> ... J&M found an article about how to add multiset semantics to datalog

<ericP> ... this is really about SQL and not about RDF

<ericP> ... (can't resolve this without J||M here)

<mhausenblas> PROPOSAL: Change status of ISSUE-9 to OPEN and Michael asks Juan/Marcelo re next steps

+1

<ericP> +1

<boris> +1

RESOLUTION: Change status of ISSUE-9 to OPEN and Michael asks Juan/Marcelo re next steps

Review of open actions/issues

<mhausenblas> ACTION: Hausenblas to mail Juan/Marcelo re ISSUE-9 [recorded in http://www.w3.org/2011/06/21-rdb2rdf-minutes.html#action01]

<trackbot> Created ACTION-135 - Mail Juan/Marcelo re ISSUE-9 [on Michael Hausenblas - due 2011-06-28].

<mhausenblas> ACTION-126?

<trackbot> ACTION-126 -- Souripriya Das to implement ISSUE-18 resolution and make sure that all class and property names are meaningful -- due 2011-05-24 -- OPEN

<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/actions/126

Souri: would like to close action-126 if everybody agree

[ souri explaining how he implemented issue-18 ]

scribe: is this solution ok?

<mhausenblas> Michael: looking at http://www.w3.org/2001/sw/rdb2rdf/r2rml/

<Souri> http://www.w3.org/2001/sw/rdb2rdf/r2rml/#LogicalTable_Class

mhausenblas: is that possible to see the changes in CVS?
... that's my wish
... fine with Souri's work, wondering if we should do micro-reviewing

cygri: if this is controversial, editors should advertise their changes
... in case anybody complains

<mhausenblas> PROPOSAL: If an Editor thinks that a change is controversial, the Editor notifies WG, silence is interpreted as consensus

<ericP> +1

sounds good

<dmcneil> +q

dmcneil: I think that changes on properties are a step backward

<ericP> i agree with David, but i am ok with the general proposal

dmcneil: prefers how they were before

<Souri> email that I had sent regarding this change (Action-126): http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Jun/0092.html

<ericP> that is, i'm happy for souri to make the change, notify us, and we push back

RESOLUTION: If an Editor thinks that a change is controversial, the Editor notifies WG, silence is interpreted as consensus

<ericP> that said, there are a couple folks who prefer terser predicate names

mhausenblas: cygri, you have a post to your proposal?

cygri, we should postpone this conversation

<dmcneil> that was Richard, not me

<mhausenblas> close ACTION-126

<trackbot> ACTION-126 Implement ISSUE-18 resolution and make sure that all class and property names are meaningful closed

<dmcneil> I created ISSUE-46 to capture the naming issue

<mhausenblas> thanks, dmcneil

<ericP> cygri pointed me at related d2r functions

cygri: anything that should produce uri, it must produce valid uris

ericP: we can provide people some functions
... usually, we don't assert functions will produce valid uris

<Souri> I am okay with raising an issue for it

cygri: I suggest we don't discuss it now, let's open an issue
... what do we do when we have to cast values to uris?
