17:09:58 <ivan> zakim, code?
17:09:58 <Zakim> the conference code is 7322733 (tel:+1.617.761.6200 sip:zakim@voip.w3.org), ivan
17:10:03 <nunolopes> Ashok: The director was anxious regarding implementations
17:10:08 <ivan> zakim, dial ivan-voip
17:10:08 <Zakim> ok, ivan; the call is being made
17:10:10 <Zakim> +Ivan
17:10:13 <nunolopes> … lots of them demonstrate public uptake
17:10:31 <nunolopes> … we agreed that we would have 2 implementations for each spec
17:10:44 <nunolopes> … from which 2 would send formal implementation reports
17:11:20 <dmcneil> i think ashok said _4_ implementations for each spec
17:12:01 <nunolopes> … can we have an idea on who would be doing these implementations?
17:12:17 <nunolopes> … is D2R doing one?
17:12:20 <dmcneil> +q
17:12:48 <Ashok> Yes, 4 for each spec, 2 of them should submit formal implementation reports
17:12:56 <dmcneil> -q
17:12:56 <nunolopes> cygri: we will be doing this but the timing might not fit with the WG timing
17:13:05 <nunolopes> s/have 2/have 4/
17:13:15 <nunolopes> Zakim, draft minutes
17:13:15 <Zakim> I don't understand 'draft minutes', nunolopes

17:14:00 <nunolopes> Ashok: ok, anybody else with a formal report for R2RML
17:14:16 <nunolopes> juansequeda: UltraWrap are almost ready to have the report out
17:14:46 <nunolopes> … for both specs
17:14:56 <boris> q+
17:15:10 <MacTed> q+
17:15:20 <Ashok> ack next
17:15:35 <nunolopes> dmcneil: we are in a similar situation to what richard described
17:15:54 <nunolopes> … we assume we'll do an implementation report but can't commit to timing
17:16:02 <nunolopes> … probably second quarter 2012
17:16:09 <ericP> q+ to say i should have a reportable implementation in a week or so
17:16:16 <dmcneil> -q
17:16:32 <nunolopes> boris: we can probably make the deadline
17:16:43 <nunolopes> … after I finish the test cases I will look into this
17:16:51 <nunolopes> … only for the R2RML spec
17:17:14 <Ashok> ack next
17:17:16 <nunolopes> … before the end of next month
17:17:35 <nunolopes> MacTed: We can try before the end of next month but cannot be sure
17:17:43 <nunolopes> … for both specs
17:17:57 <nunolopes> +q
17:18:14 <ericP> ack me
17:18:14 <Zakim> ericP, you wanted to say i should have a reportable implementation in a week or so
17:18:15 <Ashok> ack next
17:18:19 <MacTed> Zakim, mute me
17:18:19 <Zakim> MacTed should now be muted
17:18:28 <nunolopes> ericP: I should have a DM implementation
17:18:34 <nunolopes> … passing all the tests in about a week
17:18:54 <nunolopes> … I'm patching locally all the tests and was planning to then submit the diffs
17:19:08 <juansequeda> q+ to ask about the formal report
17:19:09 <nunolopes> Ashok: are you going to do a formal report?
17:19:22 <nunolopes> ericP: I intent to
17:19:56 <Ashok> q?
17:20:03 <nunolopes> Ashok: good news, as you make progress can you email the WG
17:20:23 <ericP> nunolopes: i have an implementation of both specs in XSPARQL
17:20:42 <ericP> ... i need to look at the current tests and send something in a week
17:20:51 <Ashok> ack next
17:21:11 <nunolopes> juansequeda: can you explain the process of implementation report vs test-case report?
17:21:28 <nunolopes> Ashok: what we require is one report, from 2 of the implementations at least
17:21:51 <nunolopes> … a formal document stating that we passed the tests and which failed
17:22:01 <ericP> as i understand the WG concensus, that document should be the EARL format used by SPARQL
17:22:09 <nunolopes> … and why failed
17:22:29 <nunolopes> … 2 others would just require an email stating that the implementation passed the tests
17:22:40 <nunolopes> juansequeda: we'd need the test harness code
17:22:54 <boris> http://www.w3.org/2001/sw/rdb2rdf/wiki/Submitting_Test_Results
17:23:03 <nunolopes> Ashok: the report would be in EARL format
17:23:21 <nunolopes> ericP: we follow the SPARQL WG on this
17:23:35 <nunolopes> … everybody ran the tests and sends back turtle
17:24:03 <nunolopes> … which implementation passes which tests
17:24:28 <Zakim> -Ashok_Malhotra
17:25:15 <nunolopes> … looking up an example of EARL
17:25:45 <nunolopes> juansequeda: the EARL report is part of the complete implementation report from the WG?
17:25:51 <nunolopes> ericP: yes
17:26:09 <Zakim> +Ashok_Malhotra
17:27:11 <nunolopes> ericP: for the implementation report we can go through the tests and determine which features are implemented
17:27:50 <nunolopes> … for SPARQL we had a more formal requirements
17:28:12 <nunolopes> … for us it's sufficient to have the feature names?
17:28:27 <nunolopes> … assign URLs to each feature boris identified
17:29:42 <nunolopes> Topic: test cases 
17:29:54 <nunolopes> cygri: I have some comments
17:30:15 <nunolopes> … a lot of the test cases use R2RML in a way that is not the shortest
17:30:42 <nunolopes> … like using the rr:constant construct, instead of rr:predicte
17:30:47 <Zakim> -Ashok_Malhotra
17:31:07 <nunolopes> … it's not wrong and works but would be better to show the more compact way
17:31:20 <nunolopes> … to guide people to some best practices
17:31:35 <Zakim> +Ashok_Malhotra
17:31:38 <nunolopes> … I would propose the TC use the shorter version
17:31:49 <nunolopes> juansequeda: we should have a combination of both
17:31:58 <nunolopes> … some should test the long form
17:32:10 <ericP> -> http://people.apache.org/~andy/ARQ-earl-2012-02-02.ttl example EARL
17:32:11 <nunolopes> cygri: yes, at least one use the long version
17:32:51 <nunolopes> … another point is that when there is an integer column has associated the type specifically
17:32:59 <nunolopes> … which is something we don't want
17:33:12 <nunolopes> … R2RML should use the datatype mapping
17:33:30 <nunolopes> … to get the most appropriate datatype
17:34:05 <nunolopes> … again have TC should show that this can be changed but the others should not use the datatyype specification
17:34:27 <nunolopes> … would be good to keep the TC as simple as possible
17:34:34 <ericP> +1 to minimizing complexity of test cases
17:34:49 <ericP> q?
17:34:51 <Ashok> +1 to minimizing complexity of test cases
17:34:57 <nunolopes> … since it's easier to check what goes wrong in an implementation
17:35:34 <ericP> minimized complexity will help the implementation report in the same way it helps fmplementors debug
17:35:54 <nunolopes> juansequeda: I ran all the test cases and so far they worked nicely
17:36:14 <nunolopes> … they are incremental in the way the schema is generated and features are introduced
17:36:33 <nunolopes> … on the contrary I would expect more complicated test cases 
17:36:57 <ericP> q+
17:36:59 <nunolopes> … with combinations of advanced features
17:37:14 <Ashok> ack next
17:37:15 <Zakim> juansequeda, you wanted to ask about the formal report
17:37:25 <nunolopes> boris: so far no one else has ran the test cases 
17:37:34 <nunolopes> … in the end we should include more complicated
17:37:44 <nunolopes> … but I agree with richard
17:38:06 <nunolopes> ericP: from an implementation report point of view it's easier to have simple test cases
17:38:20 <nunolopes> … opposed to more complicated ones
17:38:54 <nunolopes> … the problem with the complex ones is that we can't tell which features are not implemented 
17:39:09 <nunolopes> .. but if we can do it based on earlier tests that's ok
17:39:28 <nunolopes> Ashok: the test cases on other WG have been very minimal
17:40:23 <nunolopes> juansequeda: in TC 8C, with multiple predicate maps,  
17:40:27 <boris> http://www.w3.org/2001/sw/rdb2rdf/test-cases/#R2RMLTC0008c
17:40:43 <nunolopes> … if we combine with multiple object maps the result will be a combination of all?
17:40:49 <nunolopes> cygri: yes
17:41:13 <nunolopes> juansequeda: that's ok from the implementation side but it's strange
17:41:19 <Souri> q?
17:41:24 <nunolopes> cygri: we had a discussion on this
17:41:33 <ericP> ack ericP 
17:41:37 <Ashok> present+: Souri
17:42:07 <nunolopes> Souri: this TC has 2 predicatempas and one object map but does not have the other case 
17:42:48 <nunolopes> … you say that N predicate maps and M object maps are weird 
17:42:51 <nunolopes> juansequeda: yes
17:43:11 <nunolopes> Souri:  that generates the cartesean product
17:43:28 <nunolopes> … it is not specifically stated but is allowed
17:43:43 <cygri> q+
17:44:16 <nunolopes> juansequeda: in TC 19a, it has a subject map 
17:44:24 <nunolopes> … if the data has IRIs then its fine
17:44:28 <boris> http://www.w3.org/2001/sw/rdb2rdf/test-cases/#R2RMLTC0019a
17:44:33 <nunolopes> … but if it's a mix we have a data error
17:45:43 <nunolopes> cygri: referring to section 7.4 of the R2RML spec
17:46:02 <boris> http://www.w3.org/2001/sw/rdb2rdf/r2rml/#termtype
17:46:22 <nunolopes> … but you're right that this should not produce anything due to the space in the 3rd row
17:46:43 <nunolopes> … because if a query has any data error you will not get a partial result
17:46:47 <boris> http://www.w3.org/2001/sw/rdb2rdf/test-cases/#R2RMLTC0019a is ok
17:46:54 <boris> http://www.w3.org/2001/sw/rdb2rdf/test-cases/#R2RMLTC0019b has data-error
17:47:02 <nunolopes> … as david pointed out, data should not be silently dropped
17:47:41 <Souri> q+
17:47:43 <nunolopes> juansequeda: ok, without the 3rd row it would be fine?
17:47:54 <nunolopes> cygri: I don't think so
17:48:04 <nunolopes> … there is a base declaration used as base IRIR
17:48:11 <nunolopes> s/IRIR/IRI/
17:48:43 <nunolopes> … and is also being used in this TC to get the absolute IRI when you have relative IRIs in the data
17:49:18 <nunolopes> … to be precise every test case should have 2 inputs
17:49:25 <nunolopes> … database and base IRI
17:49:56 <Souri> Should we change "Jhon" to "John" ?
17:50:24 <nunolopes> juansequeda: in the DM graph n.6 the input would need to be changed (?)
17:51:37 <nunolopes> discussion on relative vs absolute IRIs
17:51:58 <Ashok> present+: Ivan
17:52:35 <nunolopes> ivan: ntriples doesn't allow relative IRIs
17:52:50 <nunolopes> … since we can't have @ prefixes
17:53:05 <boris> q+
17:53:08 <nunolopes> cygri:yes, this is not allowed syntactically
17:53:20 <nunolopes> … we can just call them turtle and that would work
17:53:56 <nunolopes> … I would prefer that R2RML would have absolute IRI as output
17:54:05 <cygri> ack me
17:54:07 <nunolopes> … I don't have an opinion for the DM
17:54:09 <Ashok> ack next
17:54:56 <nunolopes> Souri: do we do percent encoding in … ?
17:55:04 <nunolopes> cygri: for templates yes
17:55:29 <nunolopes> … for a column we don't , giving users the choice of doing so using a view
17:55:45 <nunolopes> … the user is responsible for producing valid iris
17:56:15 <nunolopes> Souri: if we have an rr:template what is the role of the base?
17:56:26 <Souri> ../{FIRSTNAME}
17:56:44 <nunolopes> cygri: even with the base you can have a relative IRI
17:57:07 <nunolopes> … it's simply a concatenation with the base IRI
17:57:31 <cygri> rr:template "{\"Name\"}";
17:57:33 <Souri> rr:template "{FIRSTNAME}" 
17:57:43 <nunolopes> Souri: in a simple template can we use base and percent encoding?
17:58:04 <nunolopes> cygri: checking the spec
17:58:19 <nunolopes> juansequeda: if that is the case TC 19a would not be wrong
17:58:27 <nunolopes> … since the space would be %20
17:58:47 <nunolopes> cygri: no, it uses rr:column
17:59:53 <nunolopes> Ashok: can we continue by email?
17:59:58 <Souri> first row: http://example.com/ns#Jhon -> would that be right?
18:00:04 <boris> very good question souri
18:00:20 <juansequeda> Souri, but then you have to check every single value if it's a valid IRI
18:00:32 <nunolopes> boris: for R2RML I have to input the base IRI
18:00:45 <nunolopes> cygri: most of the cases it does not matter
18:00:48 <boris> +1 to say in the begining
18:01:05 <nunolopes> … we can just add a line in the beginning of the document
18:01:20 <Zakim> - +34.91.336.aadd
18:01:22 <nunolopes> … for the ones where it si needed it should not be taken from the mapping file
18:01:36 <nunolopes> Ashok: should we have a telco next week?
18:01:55 <ericP> http://people.apache.org/~andy/ARQ-earl-2012-02-02.ttl
18:02:08 <Souri> 3rd row: http://mappingpedia.org/rdb2rdf/r2rml/tc/Juan%20Daniel -> right?
