ISSUE-72?
<trackbot> ISSUE-72 -- Bring back R2RML lookup tables -- open
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/72
Ashok: As per David's suggestion,
let's close it
... Related discussion with Kingsley re doing this with SQL
views
... or use SKOS
... which is great but should be postponed for R2RML 1.1
... suggest to incl. examples using SQL views in the spec
<MacTed> hm. issue 72 says "ACTION-170 on Richard Cyganiak to Draft a compromise translation table design for ISSUE-72 - due 2011-11-19, closed"
<MacTed> but no link to the draft in either issue or http://www.w3.org/2001/sw/rdb2rdf/track/actions/170
Juan: IMO SQL views wouldn't work for MySQL
Ted: SQL view and sub-query are
not the same
... might not work in an optimal way
... So far we've tried to avoid to get too deep into the SQL
space, so maybe not incl. examples for this?
<Zakim> cygri, you wanted to ask if ashok meant R2RML views when he said SQL views
Richard: Ashok did you mean SQL views or R2RML views?
Ashok: should be using R2RML views, that is
Richard: I see, thanks
Ashok: Additionally, I'm really interested in adding the SKOS part but should be better addressed in R2RML 1.1
PROPOSAL: Close ISSUE-72 with no
action. Add an example using an R2RML view.
... Close ISSUE-72 with no action. Add an example using an
R2RML view.
Seema: has already been addressed earlier
Richard: Concerning the
performance - if the mappings are in there declaratively then
optimising is easier (using an index)
... Dunno which DB optimise this
Juan: Ted mentioned this already - we don't go in there, re optimisation
Ted: That's the trade-off, yes
PROPOSAL: Close ISSUE-72 with no action. Add an example using an R2RML view and add a note concerning optimisation strategy.
<dmcneil> i don't think the note is necessary
Seema: It's an implementation issue so no need to add the optimisation strategy

ISSUE-57?
<trackbot> ISSUE-57 -- R2RML doesn't allow R2RML documents in RDF/XML syntax -- open
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/57
<cygri> ACTION: cygri to imlpement ISSUE-72 resolution by adding translation table example expressed asR2RML view [recorded in http://www.w3.org/2011/12/20-RDB2RDF-minutes.html#action01]
<trackbot> Created ACTION-180 - Imlpement ISSUE-72 resolution by adding translation table example expressed asR2RML view [on Richard Cyganiak - due 2011-12-27].
Ashok: Have been talking to people in the RDF world, seems that Turtle is an widely accepted syntax
<Ashok> §1 An R2RML processor is a system that, given an R2RML mapping and an input database, provides access to the output dataset. §2 An RDF graph that represents an R2RML mapping is called an R2RML mapping graph.
<Ashok> §3 An R2RML mapping document is any document written in the Turtle [TURTLE] RDF syntax that encodes an R2RML mapping graph. §4 A conforming R2RML processor MUST accept R2RML mapping documents in Turtle syntax. It MAY accept R2RML mapping graphs encoded in other RDF syntaxes.
Ashok: Suggest to follow Richard's proposal from above
<cygri> http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Dec/0078.html
Seema: All but 4 seems ok to us
Ted: can we change the MUST in 4 to a SHOULD?
<cygri> SHOULD This word, or the adjective "RECOMMENDED", mean that there
<cygri> may exist valid reasons in particular circumstances to ignore a
<cygri> particular item, but the full implications must be understood and
<cygri> carefully weighed before choosing a different course.
