16:07:07 <juansequeda> +1 from marcelo
16:07:58 <dmcneil> ashok: we have two direct mapping implementations, will there be others from a commercial company as a product?
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
16:16:16 <Zakim> On IRC I see juansequeda, boris, Seema, Souri, dmcneil, RRSAgent, Zakim, Ashok, MacTed, cygri, LeeF, iv_an_ru_, ericP, trackbot
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
16:21:24 <Ashok> present+: Seema, Boris, Eric

16:22:10 <ericP> PROPOSAL: R2RML is defined in terms of an input RDF graph. For interoperability simplicity, implementations SHOULD accept at least Turtle input.
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

16:28:25 <ericP> PROPOSED: R2RML property and classes are named per http://www.w3.org/mid/20110623160019.GB30806@w3.org 's "drop use" option
16:28:40 <ericP> +1

16:28:49 <ericP> RESOLUTION: 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.

16:32:27 <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?

16:35:58 <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?

16:44:53 <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].
