15:57:47 <trackbot> Meeting: RDB2RDF Working Group Teleconference
15:57:47 <trackbot> Date: 12 October 2010
15:57:55 <mhausenblas> Agenda: http://lists.w3.org/Archives/Public/public-rdb2rdf-wg/2010Oct/0017.html
15:57:58 <mhausenblas> Chair: Michael
15:58:32 <ericP> juansequeda, i think the use cases in http://www.w3.org/2010/10/12-Direct-Tests cover http://www.w3.org/2001/sw/rdb2rdf/wiki/All_Cases_for_Default_Mapping , but i'd like a second pair of eyes
15:58:57 <juansequeda> ericP, I was looking into this.
15:59:12 <juansequeda> Quick eyeball check says yes. But need to look at it carefully
15:59:15 <juansequeda> nicely done.

16:09:39 <Zakim> ok, ericP; the call is being made
16:09:41 <Zakim> +EricP
16:09:44 <Ashok> Richard:  Continuing work on the draft ... latest version checked in a few minutes ago
16:10:28 <Ashok> ... worked on Action 1 to address some of the issues raised last week
16:10:39 <Ashok> ... audience etc.
16:11:26 <Ashok> ... some issues not addressed 
16:12:31 <Ashok> ... like version on SQL supported

16:12:55 <Marcelo> Marcelo has joined #rdb2rdf
16:12:56 <Ashok> Ashok:  I recommend Core of latest version of SQL ... sent mail earlier
16:13:03 <Zakim> + +1.562.249.aacc
16:13:20 <mhausenblas> Zakim, aacc is Marcelo 
16:13:20 <Zakim> +Marcelo; got it
16:13:27 <Ashok> ... core not very different from SQL 99 or even SQL 92
16:13:28 <mhausenblas> Zakim, who's making noise?
16:13:39 <Zakim> mhausenblas, listening for 10 seconds I heard sound from the following: mhausenblas (49%), Marcelo (24%)
16:13:58 <mhausenblas> Zakim, mute Marcelo 
16:13:58 <Zakim> Marcelo should now be muted
16:14:24 <Ashok> Richard:  Need to work on scope of the document
16:14:45 <Ashok> ... e.g. how it interacts with formal semantics
16:15:05 <Ashok> ... added some words on target audience
16:15:50 <Ashok> Michael:  Can you talk about prerequisite knowledge ... SQL?
16:16:51 <Ashok> Michael:  Add sentence about required background
16:17:40 <Ashok> Richard:  Not yet addes inline examples
16:17:59 <Ashok> Souri:  We added a few inline examples
16:18:49 <Ashok> Michael:  Can you add the ouput also?

16:20:32 <Ashok> s/ouput/output/
16:21:04 <Zakim> +Alexandre
16:21:21 <Ashok> Michael:  Make clear what is normative
16:21:48 <betehess> Zakim, mute Alexandre

16:26:04 <mhausenblas> RRSAgent, draft minutes

16:27:34 <mhausenblas> http://www.w3.org/TR/2010/WD-rdb2rdf-ucr-20100608/
16:28:04 <Ashok> Michael:  Did you check the Usecases & Requirements document
16:28:51 <Ashok> Souri:  We can check
16:31:46 <Ashok> PatHayes: Where is the mapping
16:32:00 <Ashok> Souri:  See examples at end
16:37:16 <betehess> +1 to Pat: I don't see what the input and what is the output, especially in the default case
16:37:34 <juansequeda> We have a datalog specification of the mapping here: http://www.w3.org/2001/sw/rdb2rdf/wiki/Default_Mapping
16:37:56 <juansequeda> EricP has defined another version of the mapping based on sets http://www.w3.org/2001/sw/rdb2rdf/directGraph/
16:38:53 <Ashok> Juan:  Is the datalog mapping useful
16:39:08 <Ashok> PatHayes:  Yes, that's helpful
16:40:09 <Ashok> Michael:  Pat could you help write what the mapping is?
16:40:19 <Ashok> s/Pat/Pat,/
16:42:06 <Ashok> Souri:  Perhaps write a description of mapping at the front
16:42:32 <Ashok> Michael:  Can you write the sentence in IRC?
16:42:52 <Ashok> Souri:  I will work on it
16:43:02 <Zakim> -PatH
16:43:53 <Ashok> Michael: Can we publish next week?
16:44:40 <Ashok> Richard:  Need to do some work
16:45:13 <Ashok> ... at what point is document good enough?
16:45:30 <Ashok> Michael:  We need toexplain the mapping
16:46:31 <mhausenblas> Michael: Once the mapping semantics are defined (highlevel, in natural language) the document is good to go, IMO
16:47:18 <ericP> +1 to cygri
16:47:30 <Seema> +1 to cygri
16:47:38 <betehess> +1 to cygri
16:48:36 <betehess> q+
16:49:10 <betehess> Zakim, unmute Alexandre
16:49:10 <Zakim> Alexandre should no longer be muted
16:49:16 <mhausenblas> ack betehess
16:49:18 <Souri> A row in a relational table has <a row identifier> and a number of <column-name, value> pairs.   Such a row may be translated to RDF as follows:   subject := MAP(<row identifier>)   and <predicate, object> := <MAP(column-name), MAP(value)>, for each <column-name, value> pair.  An RDF triple is generated by combining the above as follows: <subject, predicate, object>
16:52:53 <juansequeda> q+
16:53:31 <mhausenblas> Michael: rename 2. Overview into 2. Mapping (or the like) and incl. Souri's semantics paragraph from above
16:53:33 <mhausenblas> q?
16:53:39 <mhausenblas> ack juansequeda 
16:54:45 <Ashok> DanM:  We have data, names of columns and names of tables ... actually quite simple
16:54:47 <betehess> Souri's introduction is not enough to explain what's going on: what about Primary Key, Foreign Key, Compound Key, etc. ?
16:55:31 <betehess> q+
16:56:01 <Seema> foerign keys are handled in the current document
16:56:04 <mhausenblas> ack betehess 
16:56:10 <Ashok> Souri, Ashok agree with Dan
16:56:26 <mhausenblas> Michael: +1 to Dan
16:57:13 <Ashok> Alexandre explains his position for more explanation
16:57:44 <juansequeda> betehess, does this solve your questions: http://www.w3.org/2001/sw/rdb2rdf/wiki/Default_Mapping and http://www.w3.org/2001/sw/rdb2rdf/directGraph/
16:58:32 <mhausenblas> q?
16:58:51 <MacTed> Zakim, unmute me
16:58:51 <Zakim> MacTed should no longer be muted
16:59:37 <betehess> if the simple mapping is so easy, show it to us
16:59:55 <juansequeda> betehess, did you see this: http://www.w3.org/2001/sw/rdb2rdf/wiki/Default_Mapping and http://www.w3.org/2001/sw/rdb2rdf/directGraph/
17:00:20 <betehess> juansequeda, yes, but it has not been discussed today
17:01:03 <juansequeda> betehess, we have kept that a separate discussion 
17:01:15 <Zakim> -Ashok_Malhotra
17:01:17 <juansequeda> but as I suggest, maybe we need to put these two things together
17:01:17 <MacTed> Zakim, mute me
