boris: ACTION-159 is still open
16:06:42 [juansequeda]
... I'm planning to work this week on this
16:07:04 [juansequeda]
TOPIC: Last Call
16:07:15 [juansequeda]
ashok: we have received several comments
16:07:29 [juansequeda]
... we have to acknowledge all of the comments
16:07:38 [juansequeda]
... think about them and resolve
16:07:54 [juansequeda]
... afterwards, we need to ask if whatever we end up doing is acceptable
16:08:22 [juansequeda]
... first thing to do is to acknowledge the comments
16:08:47 [juansequeda]
Can Souri, Seema and Juan reply with an acknowledgement
16:09:16 [juansequeda]
Souri: yes we can, but some emails present several comments together
16:09:31 [juansequeda]
ashok: we need to create separate issues
16:10:12 [juansequeda]

16:12:13 [juansequeda]
... we can start talking about them next week
16:12:30 [juansequeda]
... who is going to be a tpac?
16:12:51 [ericP]
q+ to ask if non WG-ers can attend?
16:13:50 [Souri]
It is unlikely that I'll be able to go to TPAC
16:13:53 [juansequeda]
juansequeda: still not sure
16:13:59 [juansequeda]
ericP: I won't be going
16:14:33 [juansequeda]
... Can non-WG members show up to the meeting?
16:14:54 [juansequeda]
ashok: I personally have no difficulty on that, but what usually happens?
16:15:52 [ericP]
PROPOSED: that the F2F at TPAC be open to the public given space and notification
16:16:04 [juansequeda]
ericP: if there is a member-only list, then it's usually closed because people say things in a small room that they wouldn't say to the whole worlds. Otherwise, it's usually open
16:16:05 [ericP]
APPROVED
16:16:12 [ericP]
(tacitly)
16:16:28 [Seema]
I won't be able to make it to TPAC
16:17:23 [juansequeda]
If no editors can attend, can we dial in?
16:17:33 [Souri]
who else is certain and certainly-not?
16:17:52 [Ashok]
Yes, I will get us a Zakim confrence
16:17:57 [juansequeda]
ashok: I will get a zakim conference
16:18:03 [Zakim]
+OpenLink_Software
16:18:10 [Souri]
s/confrence/conference/
16:18:12 [juansequeda]
... so people can dialin
16:18:17 [ericP]

16:18:20 [MacTed]
Zakim, OpenLink_Software is temporarily me
16:18:20 [Zakim]
+MacTed; got it
16:18:26 [Ashok]
present+: Ted
16:18:59 [juansequeda]
MacTed: I don't think anybody from Openlink will be able to attend f2f
16:19:06 [juansequeda]
TOPIC: Test cases
16:19:11 [boris]
http://www.w3.org/2001/sw/rdb2rdf/test-cases/
16:19:29 [juansequeda]
boris: we have 15 database cases
16:19:46 [MacTed]
Zakim, mute me
16:19:46 [Zakim]
MacTed should now be muted
16:19:49 [juansequeda]
... 15 direct mapping cases and 21 r2rml cases
16:19:58 [boris]
http://dvcs.w3.org/hg/rdb2rdf-tests
16:20:04 [juansequeda]
... currently all the test cases are in the repository
16:20:31 [juansequeda]
... I'm going to check the test cases that we have with the current version of r2rml and direct mapping
16:20:41 [juansequeda]
... and I'm going to include new testcases
16:20:54 [juansequeda]
... so I'll ask everybody to take a look at this next week
16:21:06 [juansequeda]
... new testcases for next telcon
16:21:53 [juansequeda]
ashok: this is going to be a critical thing when we want to get the standard approved.
16:22:16 [juansequeda]
... question: how do I tell if the test cases cover all the functionalities?
16:22:25 [Souri]
coverage completeness
16:22:34 [juansequeda]
boris: for every part of the spec, we have to create a test?
16:22:41 [ericP]
q+ to talk about the crazy scheme i used for coverage of SPARQL query
16:22:49 [juansequeda]
ashok: more than that. we also need to demonstrate that
16:23:27 [juansequeda]
boris: I'll think about it
16:24:07 [juansequeda]
ashok: and we only need to cover our functionalities. We dont' need to test for example jdbc connection, etc
16:24:49 [juansequeda]
... another question to think about: if you have an implementation that pass all the test cases, how do we keep a record of that?
16:25:22 [juansequeda]
boris: we started to discuss this a while ago. some ideas are on the wiki
16:25:28 [boris]
http://www.w3.org/2001/sw/rdb2rdf/wiki/TestHarness
16:25:37 [juansequeda]
ericP: I can talk about testing in sparql
16:26:00 [juansequeda]
... we had a bunch of tests that we used in our discussion.
16:26:26 [juansequeda]
... and we organized the test cases
16:26:40 [juansequeda]
... anybody would have to consume the rdf, consume the test
16:26:55 [juansequeda]
... and return the results in a specific testing language
16:28:10 [juansequeda]
(ericP explaining how they did testing in SPARQL WG)
16:32:09 [juansequeda]
boris: I will propose new feature and send it to the mailing list
16:33:17 [boris]

16:35:43 [MacTed]

16:35:43 [Zakim]
MacTed should no longer be muted
16:36:06 [MacTed]
Zakim, mute me
16:36:06 [Zakim]
MacTed should now be muted
16:38:04 [juansequeda]

16:38:16 [juansequeda]
Morph, from UPM is implementing R2RML
16:38:33 [juansequeda]
OpenLink Virtuoso will be releasing R2RML implementation any time soon

Revelytix already has an implementation of R2RML and will be revamping with the latest changes this month
16:39:13 [juansequeda]
Ultrawrap has implemented Direct Mapping and R2RML and will be releasing soon
16:39:29 [juansequeda]
XSPARQL has implemented Direct Mapping and R2RML
16:39:46 [juansequeda]
Oracle is working on it but can't say much at the moment
16:40:31 [juansequeda]
ashok: anything else?
16:41:35 [juansequeda]
ericP: yes: datatype mappings
16:43:34 [juansequeda]
(ericP talking about how he dealt with datatypes in Direct Mapping, which was a bit different from R2RML spec)
16:46:13 [juansequeda]
ericP: advice on how to deal with datatype mappings?
16:46:17 [juansequeda]
ashok: I can look at that
16:49:12 [Souri]
When we map from SQL, I thought the (virtually) generated data will all be in canonical form.
