- 17:11:59 [ericP]
- ... it makes sense for it to be optional
- 17:12:32 [ericP]
- ... at query processing time, we'll be connected so we can resolve this via a query time binding
- 17:12:45 [ericP]
- ivan: clear what doc mod is required?
- 17:12:55 [ericP]

- 17:16:12 [dmcneil]
- cygri: do we need to keep an issue open to include this in testing? (paraphrased by ericP)
- 17:17:02 [dmcneil]
- Ashok: ISSUE-23 is not open, create an action to apply it
- 17:17:05 [ivan]

- 17:18:05 [trackbot]
- http://www.w3.org/2001/sw/rdb2rdf/track/actions/92
- 17:18:40 [dmcneil]
- cygri: haven't done it yet, quite a bit of traffic on mailing list, need to think about how to do it in the document
- 17:19:12 [dmcneil]
- cygri: there was a discussion about whether there should be a primer, or something that explains how the working group deliverables work together

- +juansequeda; got it
- 17:19:28 [dmcneil]
- cygri: perhaps this could be addressed in the primer (or overview doc)
- 17:19:59 [Ashok]
- q+
- 17:20:03 [dmcneil]
- cygri: or we could just add a bit of text to each of the docs
- 17:20:23 [ivan]
- ack ivan
- 17:20:27 [ericP]
- q-
- 17:20:47 [dmcneil]
- ericP: withdraws question regarding whether a connection exists at times of query rewriting
- 17:21:11 [dmcneil]
- ivan: strongly in favor of an overview/primer document
- 17:21:32 [ivan]
- ack Ashok
- 17:21:44 [dmcneil]
- Ashok: yes, we should write a primer, but people might not read it
- 17:21:53 [ivan]
- q+
- 17:22:06 [dmcneil]
- Ashok: also, add at least one paragraph to each doc talking about the relationships between the docs
- 17:22:24 [ericP]
- OWL primer?
- 17:22:25 [dmcneil]
- ivan: may not agree
- 17:22:28 [ivan]
- http://www.w3.org/TR/owl2-overview/
- 17:23:10 [dmcneil]
- ivan: points to the OWL document that is brief (1.5 pages) that shows how all of the pieces fit together
- 17:23:17 [juansequeda]
- +1 to an overview document
- 17:23:23 [dmcneil]
- ivan: this document was well received
- 17:23:23 [cygri]
- q+
- 17:23:32 [ivan]
- ack ivan
- 17:23:35 [betehess]
- q+ to comment quickly on how we could use the spec grouping feature, like http://www.w3.org/standards/techs/rdfrel.html#w3c_all
- 17:23:50 [ivan]
- ack cygri
- 17:24:40 [dmcneil]
- cygri: probably a short document because there is not a long list of deliverables (like OWL), but it will make it seem more complicated
- 17:24:54 [dmcneil]
- cygri: if it can be addressed easily in the main document, then it is a good idea
- 17:25:13 [dmcneil]
- cygi: the main documents are Direct Mapping and R2RML documents
- 17:25:35 [dmcneil]
- cygri: different paragraph in each referring to the other
- 17:26:04 [Souri]
- q+
- 17:26:05 [dmcneil]
- cygri: this would produce a more usable set of documents
- 17:26:40 [dmcneil]
- cygri: could try putting the content in the wiki and then assess whether it warrants a separate document
- 17:26:43 [ivan]
- ack betehess
- 17:26:43 [Zakim]
- betehess, you wanted to comment quickly on how we could use the spec grouping feature, like http://www.w3.org/standards/techs/rdfrel.html#w3c_all
- 17:27:09 [betehess]
- http://www.w3.org/standards/techs/rdfrel.html#w3c_all
- 17:27:16 [dmcneil]
- betehess: it is possible to create a new group to have all the specification in one group
- 17:27:40 [ivan]
- q?
- 17:27:46 [dmcneil]
- betehess: dependencies between documents is difficult to manage
- 17:28:11 [ivan]
- ack Souri
- 17:28:12 [cygri]
- q+
- 17:28:29 [cygri]
- q-
- 17:28:51 [dmcneil]
- Souri: the R2RML document needs to be extended to describe how direct mappings can be used in a custom mapping
- 17:29:00 [betehess]
- /me would like to recall we'll also have a document for the tests
- 17:29:09 [dmcneil]
- Souri: need examples/test cases that show such hybrid mappings, this could go in a "primer"
- 17:29:31 [betehess]
- ivan, open an issue :-)
- 17:29:34 [ericP]
- q+
- 17:29:43 [ivan]
- ack ericP

- illustrating hybrid mappings (some portion R2RML, some portion DM)
- 17:29:50 [juansequeda]
- q+
- 17:30:05 [ivan]
- q+
- 17:30:06 [dmcneil]
- ericP: currently the Direct Mapping refers to the R2RML spec
- 17:30:23 [ivan]
- ack juansequeda
- 17:30:29 [dmcneil]
- ericP: the R2RML spec will need a reference to the Direct Mapping for the feature of using Direct Mappings in a custom mapping
- 17:30:35 [dmcneil]
- ericP: so this will be covered anyway
- 17:30:54 [ivan]
- ack ivan
- 17:30:57 [dmcneil]
- juansequeda: short, summary document could be a good thing for the wider community
- 17:31:41 [dmcneil]
- ivan: a summary document that clearly shows where to start reading makes sense
- 17:32:11 [ivan]
- ACTION-93?
- 17:32:11 [trackbot]
- ACTION-93 -- Souripriya Das to identify not-mapping vs. default-mapping issues in R2RML/DM (Wiki or via mail) -- due 2011-02-08 -- OPEN

- ivan: re-interpret ACTION-92 to be write proposed content on the wiki
- 17:32:38 [dmcneil]
- Souri: discussed general approach last week, haven't worked on it much, not difficult to get done
- 17:32:45 [ivan]
- ACTION-97?
- 17:32:45 [trackbot]
- ACTION-97 -- Richard Cyganiak to look into D2RQ implementation and update http://www.w3.org/2001/sw/rdb2rdf/wiki/Entity_disambiguation -- due 2011-02-08 -- OPEN

- Souri will write down more details
- 17:32:58 [dmcneil]
- on Action-93
- 17:33:41 [dmcneil]
- cygri: ACTION-97 is to document how D2RQ supports translation tables
- 17:34:02 [dmcneil]
- ivan: why is this relevant?
- 17:34:44 [dmcneil]
- cygri: charter requires that we try and re-use entity URIs, question is how to get external URIs into the output of the mapping
- 17:34:48 [ivan]
- ACTION-96?
- 17:34:48 [trackbot]
- ACTION-96 -- Richard Cyganiak to capture this (multiple subject maps) and other (future) potential error cases in the Wiki (ISSUE-16) -- due 2011-02-08 -- OPEN

- 17:35:12 [trackbot]
- http://www.w3.org/2001/sw/rdb2rdf/track/issues/16
- 17:35:44 [dmcneil]
- cygri: ACTION-96 - since R2RML is expressed in RDF and there is not a schema that clearly expresses what is valid, wanted to collect cases where cardinality was violated
- 17:36:09 [dmcneil]
- cygri: we decided to collect such cases on a wiki page (e.g. "problem multiple subject maps")
- 17:36:29 [dmcneil]
- cygri: for each of those we could document the solution (e.g. "raise error", etc.)

- +juansequeda
- 17:37:10 [dmcneil]
- cygri: agrees to keeping this action item open
- 17:37:39 [Souri]
- We need to prioritize ... and in my opinion, Primer should come later (we can start on it, but), we need to push out the next draft sooner
- 17:37:45 [dmcneil]
- ivan: the R2RML editor's draft is quite different from the official draft
- 17:37:49 [Souri]

- 17:38:27 [dmcneil]
- ivan: the gap between the two drafts is so large that an updated draft needs to be done soon
- 17:38:53 [dmcneil]
- Souri: agrees, and thinks the official draft can be updated with issues marked
- 17:39:15 [ivan]
- ack cygri
- 17:39:23 [dmcneil]

- 17:42:50 [trackbot]
- http://www.w3.org/2001/sw/rdb2rdf/track/issues/11
- 17:43:08 [dmcneil]
- juansequeda: I did ACTION-98 already
- 17:43:44 [dmcneil]
- juansequesa: this issue was where "foreign key" was incorrectly typed as "candidate key" in the spec
- 17:43:52 [ivan]
- ACTION-99?
- 17:43:52 [trackbot]
- ACTION-99 -- Juan Sequeda to change ISSUE-13 to postponed and add ref from ISSUE-11 to ISSUE-13 -- due 2011-02-08 -- OPEN

- 17:45:01 [dmcneil]
- ivan: what is the status of the Direct Mapping?
- 17:45:42 [dmcneil]
- ericP: there is not much new information, new information will come from Juan's work in Chile (with Marcello (?))
- 17:46:23 [dmcneil]
- ericP: an open question is whether the Direct Mapping produces persistent identifiers for rows without primary keys
- 17:46:52 [dmcneil]
- juansequeda: there is still an open issue related to avoiding blank nodes
- 17:47:28 [dmcneil]
- juansequeda: there are several issues that we can begin discussing: e.g. hierarchical relationships, etc.
- 17:47:42 [betehess]
- the denotational semantics does *not* need a primary key and uses bnode very well https://dvcs.w3.org/hg/FeDeRate/file/0407570a9826/directmapping/src/main/scala/DirectMapping.scala#l37
- 17:47:45 [dmcneil]
- ivan: would like to come back to the publication issue before the end of the call
- 17:47:54 [dmcneil]
- ivan: what open issues to dicsuss now?
- 17:48:16 [dmcneil]
- ericP: maybe we can knock off the "primary key is a foreign key" issue
- 17:49:27 [betehess]
- you can try hier_table in http://this-db-really.does-not-exist.org/ with and without "Detects hierarchy relation"
- 17:49:36 [dmcneil]
- ericP: there was a model for the mapping, the considered the case of whether a primary key is also a foreign key, this is one of the 3 ways users express hierarchies in RDBMS, created a solution for expressing this in the mapping
- 17:50:46 [dmcneil]
- ericP: the behavior with "detects hierarchy" turned off is the simple behavior
- 17:50:49 [juansequeda]
- q+ to discuss the three possible cases
- 17:51:07 [ivan]
- ack juansequeda
- 17:51:07 [Zakim]
- juansequeda, you wanted to discuss the three possible cases
- 17:51:12 [dmcneil]
- ericP: the proposal is that this simple behavior be the behavior that is implemented when a primary key is a foreign key
- 17:51:42 [dmcneil]
- juansequeda: there are three possibilities: 1) always detect hierarchy 2) never detect as hierarchy 3) make it an option to detect this as a hierarchy
- 17:52:01 [betehess]
- ivan, yes
- 17:52:04 [dmcneil]
- ivan: how would option "3" work, the beauty of the Direct Mapping is it just works
- 17:52:16 [dmcneil]
- juansequeda: there could be "flavors" of direct mappings
- 17:52:17 [betehess]
- q+ to say I'm against any switch
- 17:52:33 [dmcneil]
- ivan: would rather not see a switch (personal opinion)
- 17:52:44 [ivan]
- ack betehess
- 17:52:44 [Zakim]
- betehess, you wanted to say I'm against any switch
- 17:52:55 [dmcneil]
- betehess: agrees with ivan

- q+
- 17:53:23 [juansequeda]
- q+
- 17:53:38 [cygri]
- +1 to have only one flavour. if you want switches, go to r2rml, it has plenty
- 17:53:43 [dmcneil]
- betehess: put the switch into the demo application to show what is being discussed, not to advocate for a switch in the Direct Mapping
- 17:53:46 [ivan]
- ack ivan
- 17:54:13 [dmcneil]
- ivan: proposes publishing the document with the simplest approach, put in a statement that this is still an open issue, ask community for feedback
- 17:54:19 [ivan]
- ack juansequeda
- 17:54:21 [betehess]
- sounds like a wise proposal
- 17:54:23 [ericP]
- q+ to say we've already done one round without feedback
- 17:54:26 [dmcneil]
- juansequeda: agrees with ivan
- 17:54:30 [ivan]
- ack ericP

- 17:54:36 [dmcneil]
- Ashok: agrees with ivan
- 17:54:48 [dmcneil]
- ericP: we tried that, and the community did not respond
- 17:55:01 [dmcneil]
- ericP: so proposes that we just go with the simple solution
- 17:55:15 [dmcneil]
- ivan: has no problem with that
- 17:56:15 [dmcneil]
- ericP: the compromise is that most primary keys appear as literals in the output triples
- 17:56:39 [juansequeda]
- ericP, which example are you talking about?
- 17:56:51 [dmcneil]
- ericP: but id the PK is also a FK then it appears only as a reference to another tuple
- 17:57:33 [dmcneil]
- s/tuple/triple/
- 17:58:49 [dmcneil]
- cygri: in general agrees with proposal to proceed, there wasn't a really clear answer, so simplest is safest
- 17:59:13 [Souri]
- To me pk=fk case seems to indicate presence of a simple 1:1 join between a parent table and a child table (which often appears in a normalized DB design) ... is there much more to it?
- 17:59:15 [ericP]
- PROPOSAL: unary primary keys which are also foreign keys are treated exactly as other unary foreign keys
- 17:59:18 [betehess]
- for the record, this is were we don't take unary foreign key in the scalars function: https://dvcs.w3.org/hg/FeDeRate/file/0407570a9826/rdb/src/main/scala/RDB.scala#l129

- ivan: can we stay on for a few minutes to discuss publishing Direct Mapping
- 18:01:15 [ericP]
- q+ to suggest we lose review attention
- 18:01:25 [dmcneil]
- ivan: proposes that the Direct Mapping document be published at the same time as the R2RML document without the Chilean work from Juan
- 18:01:27 [betehess]
- are the r2rml people ready to publish too?

- ack ivan
- 18:02:12 [dmcneil]
- ericP: fears publishing document with few changes because it endangers the public review capacity
- 18:02:20 [Souri]
- I am ok with publishing R2RML next draft alone
- 18:02:52 [betehess]
- +1 to ivan comment re: publication of both documents makes sense
- 18:02:55 [dmcneil]
- ivan: agrees with respect to Direct Mapping, but R2RML doc has changed a lot, needs to be published soon, is a good habit to publish them together
- 18:03:44 [dmcneil]
- betehess: agrees with ivan
- 18:03:55 [dmcneil]
- ericP: thinks the review capacity is more important
