<dmcneil> I am the 314 number
<scribe> scribenick: ivan
<scribe> scribe: Ivan
Ashok: minutes from last meeting
<Ashok> PROPOSAL: Accept the minutes of F2F meeting http://www.w3.org/2011/11/03-RDB2RDF-minutes.html
Ashok: any objections?
... carry 1
... carry 2
... carried!
Souri: I was also present after
12
... it does not show my name at the top
...: -(
Ashok: I was not very strict, but
it ought to have your name there
... approve the minutes with this amendment?
...
...
...
Ashok: resolved
Ashok: what we did was to go
through the last call comments
... spent lot of time on david's comments
... and then the comments on the wiki
<Ashok> http://www.w3.org/2001/sw/rdb2rdf/wiki/Last_Call#5_DM_and_R2RML:_comments_on_working_drafts
Ashok: we went to the first 8 of
those
... we did not do Ivan's because he had some comments on the
direct mapping, but we did not have eric and juan on the
call
... but we do not have eric right now either
... juan is on irc only
... we have seema and souri here, let us do number 10
<Ashok> http://lists.w3.org/Archives/Public/public-rdb2rdf-comments/2011Oct/0001.html
Ivan: I have received a mail from
Richard, and have answered to them; I am o.k. with the comments
for the Last Call document
... I have some issues on the examples, but that does not refer
to the LC document, we can handle them later
<Souri> http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Nov/0025.html (Ivan's reply to Richard's changes)
<juansequeda> Ivan's comments on the DM are just editorial, right?
Ashok: we skip comment 11 because
that is on DM
... let us look number 12 from David
http://lists.w3.org/Archives/Public/public-rdb2rdf-comments/2011Oct/0007.html
Ashok, is that resolved?
dmcneil: yes, this is the same
issue, and having talked to Richard and the new version has
changed
... I suppose that will take my comments into account
<Souri> modified section in the editorial draft: http://www.w3.org/2001/sw/rdb2rdf/r2rml/#logical-tables
Ashok: next is from Fabian Pijcke, number 13
<Ashok> http://lists.w3.org/Archives/Public/public-rdb2rdf-comments/2011Oct/0008.html
Ashok: he is having difficulties
creating identifiers
... he wants to have specific construct
<dmcneil> +q
Ashok: does this make sense?
Souri: he is try to say that a processor should generate instead of the r2rml author having to write that
Ashok: he wants a construct
<Ashok> rr:subjectMap [ rr:termType rr:BlankNode; ];
dmcneil: there is a separate
discussion... what he wants a to do is to generate r2rm to
generate direct mapping?
... the final message (and Richard sent him) is that this is a
feature in sql
... he agreed with that
Ashok: but sql is not doing to do that
dmcneil: true, but this is recognition that this is not something we can do
<Ashok> Response: http://lists.w3.org/Archives/Public/public-rdb2rdf-comments/2011Nov/0017.html
Ashok: so we have to wait for his
answer
... Issue #14, datatype mapping question, this is richard and
eric
... they seem to look at it quite differently
... skip it now
... number 15
<Ashok> http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Nov/0000.html
Souri: I have something
more
... the idea from my point of view that we have to distinguish
the plus that is already in the data to handle it
... part of a URI
<Souri> "C++ 2.3.0"
Souri: if that is a key, I should
be able to distinguish between '+'
... but richard asked why not using the encoding in the draft,
ie, a % encoding
... i was expecting that type of encoding
Ashok: you would encode characters in the value and that would get you around it?
Souri: yes
<Souri> "C++ 2.3.0" should become "C++%202.3.0"
Ashok: if you are o.k. with this solution, could you send a clear reply to this and we can close this
Souri: Richard has already
started a thread on that one on the comment list
... the latest email
<Souri> Here is the latest email on this thread about PLUS sign: http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2011Nov/0002.html
Ashok: souri, if you are happy with this, you should answer
Souri: but this has to be agreed
upon for the DM, and the DM editors should look at it
... this is really for the DM editors
juansequeda: for me, it is
fine
... but eric should also reply
Souri: I can reply that I am happy, and ask the dm editors explicitly
Ashok: Juan, there were a number
of dm issues that we postponed because you were not here
... would you like to go through them?
juansequeda: these are mostly editorial
Ashok: editorials was from ivan
and fabian
... but these are lc issues, we have to be formal
... you have to tell us if you agreed
juansequeda: I will go through those in the next 2 days
Ashok: look at the wiki, look at the comments, look at particular comments 9, 11, and then the last one we talked about, 15, and then reply to us

ISSUE-68?
<trackbot> ISSUE-68 -- Multiple PredicateMaps in a PredicateObjectMap -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/68
Ashok: we have spoken on
this
... I have the feeling that souri and richard do not agree on
this
<Souri> Issue-68: P{+}O shortcut
<trackbot> ISSUE-68 Multiple PredicateMaps in a PredicateObjectMap notes added
<Souri> PO{+}
Souri: my opinion is that it is
not critical for us to put in this shortcut
... why not adding other shortuts
... the amount of additional writing is not much
... you can always define the object map to be uri, and use
that again and again
... we have to be conservative on shortcuts
Ashok: the only thing we can do
is to open the issue
... We agree to open issue 68
Ivan: how do we decide that?
Ashok: one of the telco when we get both of them, we have to agreement on that
ISSUE-69?
<trackbot> ISSUE-69 -- datatype sizes -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/69
Ashok: this is related to the
earlier issues
... is this related to making one mapping
ericP: Everybody wants to have
one
... Richard and I did a different approach
... those reflect on what the recipes should look like
... his notion is 'here is the recipe to convert stuff from db
to rdf, the precision depends on the db'
... my approach is that it is a fixed values for that, and here
is the scheme you should follow if you extend
Ashok: let us just open this, then we should discuss when both of you are here we should discuss it
ericP: we are both pretty good in
describing our opinion
... and also the other's opinion
... we know what to do for any opinion
... we are at the point that really the wg has to decide
... the other question is whether we rely on xsd or on sql
Ashok: rdf uses xsd, right?
ericP: rdf core does not say that you should use the canonical forms of the xsd types
Ashok: this is not our business, but worth taking up with the rdf core guys
ericP: if they do not do that, and xsd does not really care about this, then it is our business
Ashok: let open the issue
... we agreed to open issue 69
ISSUE-70?
<trackbot> ISSUE-70 -- Behaviour of fully qualified column names in rr:sqlQuery -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/70

issue last week
... it needs to be opened
Ashok: let us open it

<trackbot> ISSUE-71 -- Column name collisions between child and parent queries in RefObjectMaps -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/71
Ashok: I think we also talked
about it
... open it?
... no objection, let us open 71
ISSUE-72?
<trackbot> ISSUE-72 -- Bring back R2RML lookup tables -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/72
Ashok: let us open it for when richard is on the call
Souri: we came up with a proposal
that is simpler than the other one, that is why we decided to
drop it
... there are two proposals sitting there
... that is the status
Ashok: let us open this issue 72
ISSUE-73?
<trackbot> ISSUE-73 -- Section 11 cleanup -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/73
Ashok: this is again david's
comment
... we should open this and wait until we can do 68 and
72
... objections?
...
...
... let us open issue 73
ISSUE-74?
<trackbot> ISSUE-74 -- Re-organize the table in Appendix B.2 -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/74
Ashok, we should open this, too
scribe: david says that when
cliking on the document he gets to the schema document
... but then somebody pointed out that the schema document is a
separate document
dmcneil: ivan addressed it and the issue is for the table
Ashok: let open issue 74, too
ISSUE-75?
<trackbot> ISSUE-75 -- Reconsider rr:tableName syntactic sugar -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/75

comment
... this requires discussion
... this is also a shortcut, righ?
... Let us open 75, and discuss it later
<Souri> Since Eric is here, we can also bring up the percent-encoding issue (that came up from my PLUS sign related comment) for a introductory discussion
ISSUE-57?
<trackbot> ISSUE-57 -- R2RML doesn't allow R2RML documents in RDF/XML syntax -- raised
<trackbot> http://www.w3.org/2001/sw/rdb2rdf/track/issues/57
Ivan: this is a leftover, was actually opened by the facts...
Ashok: eric, there were 3 lc comments on dm, if you could look at them to answer them; juan has taken an action, numbers 9, 11 and 15
<Souri> also, PLUS sign comment
Ashok: if you could look at them
Eric: yes, will do
Ashok: I am encouraged by the
progress, some of these issues are tiny
... there are a couple of big ones
