16:08:59 [Zakim]: + +539149aabb
16:09:11 [boris]: zakim, aabb is boris
16:09:11 [Zakim]: +boris; got it
16:10:14 [dmcneil]: ashok: do we have concensus that we do not need any more R2RML syntaxes? i.e. Turtle is enough
16:12:30 [juansequeda_]: juansequeda_ has joined #rdb2rdf
16:13:15 [dmcneil]: from the charter: "The mapping language SHOULD have a human-readable syntax as well as XML and RDF representations of the syntax for purposes of discovery and machine generation. "
16:13:32 [dmcneil]: PROPOSAL: R2RML will only define the Turtle syntax
16:13:47 [Souri]: q+
16:14:06 [Ashok]: ... and it meets the human-readable requirements
16:15:52 [Zakim]: +ericP
16:16:13 [MacTed]: Zakim, who's here?
16:16:13 [Zakim]: On the phone I see dmcneil, MacTed (muted), Ashok_Malhotra, +1.562.686.aaaa, Souri, Seema, boris, ericP

16:16:33 [juansequeda]: Zakim, aaaa is me
16:16:34 [Zakim]: +juansequeda; got it
16:18:21 [Souri]: q+
16:18:25 [dmcneil]: +q
16:19:26 [dmcneil]: souri: R2RML is defining an RDF model, as long as a mapping author writes an RDF document that corresponds to the RDF model, that is fine
16:19:37 [ericP]: PROPOSAL: R2RML is defined in terms of an input RDF graph. For interoperability simplicity, implementations are SHOULD accept at least Turtle input.
16:21:01 [juansequeda]: zakim, mute me
16:21:01 [Zakim]: juansequeda should now be muted

16:22:34 [dmcneil]: +1
16:22:37 [ericP]: +1
16:23:03 [ericP]: RESOLUTION: R2RML is defined in terms of an input RDF graph. For interoperability simplicity, implementations SHOULD accept at least Turtle input.
16:23:21 [dmcneil]: ashok: next issue is property names
16:24:45 [ericP]: q+ to say that cygri and i were happy with only case distinction on class names
16:25:05 [Souri]: rr:subjectMap property rr:Subjectmap
16:25:14 [ericP]: that's pretty common in RDF
16:25:21 [dmcneil]: i am having a hard time hearing
16:25:25 [Souri]: rr:subjectMap property rr:SubjectMap
16:26:26 [ericP]: http://www.w3.org/mid/20110623160019.GB30806@w3.org
16:28:25 [ericP]: PROPOSED: R2RML property and classes are named per http://www.w3.org/mid/20110623160019.GB30806@w3.org 's "drop use" option

16:29:12 [Ashok]: ACTION Souri to implement names as resolved above
16:29:13 [trackbot]: Created ACTION-136 - Implement names as resolved above [on Souripriya Das - due 2011-07-05].
16:30:02 [ericP]: +1 to IRIs for term types
16:30:15 [MacTed]: action 136 is going to need clarification... "resolved above" won't make sense when we look at it later.
16:30:15 [trackbot]: Sorry, couldn't find user - 136

16:31:29 [Zakim]: +ericP
16:32:27 [MacTed]: Zakim, who's noisy?
16:32:40 [Zakim]: MacTed, listening for 11 seconds I heard sound from the following: ericP (100%), Souri (14%)
16:33:02 [dmcneil]: discussion of ISSUE-45
16:33:12 [dmcneil]: souri can write up a proposal of IRIs to use
16:34:00 [Ashok]: ACTION: Souri to create proposal for IRIs to resolve ISSUE-45
16:34:00 [trackbot]: Created ACTION-137 - Create proposal for IRIs to resolve ISSUE-45 [on Souripriya Das - due 2011-07-05].
16:34:02 [Souri]: thinking of something simple like: rr:IRI, rr:BlankNode, rr:Literal
16:34:16 [dmcneil]: next is ISSUE-47
16:34:38 [dmcneil]: +q
16:34:41 [MacTed]: issue 47?
16:34:48 [MacTed]: issue-47?
16:34:48 [trackbot]: Sorry... I don't know anything about this channel
16:35:11 [MacTed]: trackbot, start meeting
16:35:11 [trackbot]: Sorry... I don't know anything about this channel
16:35:11 [trackbot]: If you want to associate this channel with an existing Tracker, please say 'trackbot, associate this channel with #channel' (where #channel is the name of default channel for the group)
16:35:20 [ericP]: q+
16:35:21 [Souri]: q+
16:35:43 [MacTed]: trackbot, associate this channel with #RDB2RDF
16:35:43 [trackbot]: Associating this channel with #RDB2RDF...
16:35:43 [trackbot]: Sorry... I don't know anything about this channel

16:35:58 [dmcneil]: q-
16:36:10 [MacTed]: unhelpful, bot...
16:36:57 [dmcneil]: souri: the question is whether we automatically apply percent encoding to the data values used as IRIs
16:37:33 [dmcneil]: souri: would prefer to do this automatically because it simplifies it for the user
16:38:26 [dmcneil]: souri: we could refer to the standard for this
16:38:57 [ericP]: i propose all characters outside of ([^<>"{}|^`\]-[#x00-#x20])* per http://www.w3.org/TR/rdf-sparql-query/#rIRI_REF
16:40:57 [Ashok]: ... Percent encode all characters outside of ([^<>"{}|^`\]-[#x00-#x20])* per http://www.w3.org/TR/rdf-sparql-query/#rIRI_REF
16:41:35 [dmcneil]: ericP: still a question of whether to convert spaces to "+" instead of "%20"
16:41:36 [Souri]: In Oracle utl_url.escape('http://www.acme.com/a url with space.html') Returns: http://foo.com/a%20url%20with%20space.html
16:43:01 [Souri]: space => %20
16:43:32 [boris]: most URL encoders convert space to %20
16:43:53 [dmcneil]: ashok: it is hard to make the argument that we should follow the standard approach with one exception
16:44:12 [dmcneil]: q+
16:44:16 [MacTed]: + is LONG deprecated as space substitute
16:44:28 [MacTed]: Zakim, unmute me
16:44:28 [Zakim]: MacTed should no longer be muted
16:44:49 [MacTed]: q?
16:44:52 [MacTed]: q+
16:44:53 [ericP]: q-
16:44:59 [Souri]: ack souri
16:45:01 [Ashok]: ack next
16:45:16 [Ashok]: ack next
16:45:34 [ericP]: d2r has some functions near this
16:46:13 [dmcneil]: MacTed: using + for space is a long deprecated concept
16:46:22 [dmcneil]: we should not do anything to produce a +
16:46:36 [dmcneil]: ericP: where is it deprecated?
16:46:46 [Zakim]: -ericP
16:47:07 [ericP]: weak!
16:47:17 [ericP]: +1 to functions
16:47:36 [Zakim]: +ericP
16:47:51 [dmcneil]: dmcneil: how about as we discussed on the mailing list, to have the mapping explicitly invoke conversion functions
16:47:58 [Souri]: q+
16:47:59 [dmcneil]: this removes the automatic behavior
16:48:08 [dmcneil]: but we have to specify the functions
16:48:58 [Souri]: rr:template "xyz/{rr:foo(empno)}"
16:49:13 [MacTed]: ericP - http://en.wikipedia.org/wiki/Percent-encoding#The_application.2Fx-www-form-urlencoded_type
16:50:09 [Souri]: or more like: rr:template "xyz/{rr:foo({empno})}"
16:50:24 [MacTed]: Zakim, mute me
16:50:24 [Zakim]: MacTed should now be muted
16:51:28 [dmcneil]: ashok: let's wait and discuss further in two weeks
16:52:28 [dmcneil]: next to discuss is ISSUE-22
16:53:09 [dmcneil]: next, ISSUE-36
16:53:32 [dmcneil]: ashok: Richard proposed we postpone this
16:53:33 [dmcneil]: +1
16:54:01 [Souri]: +1
16:54:07 [boris]: +1
16:54:08 [ericP]: +1
16:54:13 [dmcneil]: ashok: i.e. the proposal is that we not define the schema in the mapping output
16:54:47 [dmcneil]: RESOLUTION: Resolve ISSUE-36 as POSTPONED. The initial version of R2RML will not provide special features for creating schema triples.
16:55:47 [MacTed]: Zakim, unmute me
16:55:47 [Zakim]: MacTed should no longer be muted
16:55:51 [MacTed]: q+
16:55:58 [dmcneil]: ISSUE-37
16:56:00 [boris]: ?
16:56:07 [dmcneil]: ashok: why would we even consider doing this?
16:56:24 [juansequeda]: what is issue-37?
16:56:32 [Souri]: q?
16:56:40 [boris]: ISSUE-37?
16:56:40 [trackbot]: ISSUE-37 -- Allow specifying DB connection details in the R2RML mapping -- open
16:56:40 [trackbot]: http://www.w3.org/2001/sw/rdb2rdf/track/issues/37
16:56:41 [Souri]: ack souri
16:57:07 [dmcneil]: MacTed: the reason is not to specify the connection so much as clarifying the data source
16:57:14 [dmcneil]: part of the map to the data includes where it is
16:57:39 [dmcneil]: e.g. row id's may change as the db is moved, and these may be used in URIs
16:57:43 [Souri]: rowids may change due to data movement within the same database
16:57:46 [Ashok]: q?
16:58:15 [dmcneil]: souri: not clear why we would do this, row ids can change even without moving the database
16:58:52 [dmcneil]: ashok: let's wait to try and resolve this issue
16:59:35 [dmcneil]: ashok: would you like a single statement for this
16:59:50 [dmcneil]: MacTed: could do that, that essentially means it is like a JDBC connection string
16:59:56 [ericP]: imo, ODBC URLs are hilariously varied
17:00:43 [ericP]: i often move stuff from server to server without changing primary keys
17:01:13 [boris]: also, the connection details can be optional
17:01:15 [boris]: ?
17:01:23 [ericP]: in fact, all of the databases i download (1/6 months) have pks which have been pre-filled
17:02:02 [Ashok]: ACTION Ted to create proposal for issue 37
17:02:02 [trackbot]: Created ACTION-138 - Create proposal for issue 37 [on Ted Thibodeau - due 2011-07-05].
