And reviewing some Bps. 14:13:08 ...I was reviewing the BP on data vocabularies, and opened some issues and are discussing them with Antoine 14:13:19 ...I hope we can get consensus and some examples for the end of next week. 14:13:51 ...For the Data Access section: Newton and I were discussing examples for this 14:13:55 The ISSUE-213 14:13:55 hadleybeeman: is it your typing that's coming over the lines? can you mute pls 14:14:00 ...And also the BP about use of REST for APIs.

Does the group agree? 14:15:06 ...Or are there other suggestions? Mark sent some. 14:15:13 ...GTFS is easy to work with. 14:15:22 +1 to using GTFS in examples 14:15:22 ...This is just an example, not to say you SHOULD use this vocabulary 14:15:34 ...Phil, have you talked with Christophe re the Data Preservation section? 14:15:56 +1 to GTFS at examples 14:15:58 phila: Re GTFS: as an example, that's fine. (The G used to stand for "Google"; now it's "General".) Almost everyone uses it. 14:16:06 ...Stations, bus stops, timetables, etc. 14:16:21 ...As long as it's just in the examples and we aren't saying "you must use this"; that's fine. 14:16:34 ...I did contact Christophe, who responded with a pull request with examples. 14:16:44 ...I haven't yet asked him to look at the running example. 14:17:00 ...I haven't seen what he's written yet (in that PR), but if the example doesn't fit that, I'll see if I can edit it. 14:17:09 BernadetteLoscio: Okay, I'll look at his PR. 14:17:17 ...and I'll reply on email. 14:17:19 q? 14:17:21 q+ 14:17:47 BernadetteLoscio: So we are working on the doc, reviewing the BPs. There is still stuff to do. This week I'll send emails asking for feedback about specific stuff. 14:17:53 ... From the whole group. 14:17:57 q+ to ask about next publication date 14:18:11 ...Soon we need to prepare the doc to publish the next draft, so it's good to get feedback now. 14:18:13 q? 14:18:32 ack newton 14:18:35 ack newton 14:18:52 Title: Use Content Negotiation when providing the same resource with different formats 14:18:54 newton: Re Conneg: I wrote a draft on this and have discussed with Bernadette 14:19:06 ...I've changed the title 14:19:13 link, newton 14:19:14 ? 14:19:21 ...With this title, this BP could be basian or not 14:19:38 ...I don't have a link yet, but I will put the text on my GitHub and send to the group 14:19:40 PWinstanley has joined #dwbp 14:19:48 ...It's better to discuss it later, with more content. 14:19:50 present+ PWinstanley 14:19:55 ISSUE-213 14:19:55 ISSUE-213 -- Changes on BP about REST APIs -- raised 14:19:55 http://www.w3.org/2013/dwbp/track/issues/213 14:20:00 yaso: And the BP for REST APIs? 14:20:40 BernadetteLoscio: As Newton said on the issue, it's more because the idea of us saying you should use REST APIs as an approach to implementation — instead of saying this on the title of the BP 14:20:51 Makx has joined #dwbp 14:20:54 ...So the title could be more generic, like "use APIs", and then on the approach implementation section 14:21:02 ...you could say that one option would be to use RESTful APIs 14:21:16 ...I don't think it's in the scope of the group to say how to implement a RESTful API 14:21:18 Not sure I agree with that but I'll need to look at it more carefully, i.e. I have an idea we should be firmer in recommending REST 14:21:31 ...If you're going to use an API, you should use a RESTful API, but say this is an example. 14:21:36 +1 to phil from me 14:21:46 yaso: I agree with Phil. Maybe we should talk more? 14:21:54 BernadetteLoscio: We just started the discussion. 14:22:14 yaso: I agree that we don't need to mention the REST word. But I don't know if we don't have to mention the methods related to hypermedia and stuffy 14:22:23 ...Maybe we should carry on the discussion on email? 14:22:34 ...Newton or Bernadette, could you send this around? 14:22:39 BernadetteLoscio: It's on the issue (213) 14:22:49 thanks Hadley! 14:22:53 newton: We could recommend some links on it 14:23:03 Caroline has joined #DWBP 14:23:05 ...But I'm not sure we should get more specific 14:23:05 q? 14:23:06 q? 14:23:10 ack phil 14:23:10 phila, you wanted to ask about next publication date 14:23:12 ack phila 14:23:27 phila: Newton, BernadetteLoscio, when do you think we can have a new publication? (ideally before Christmas) 14:23:30 BernadetteLoscio: Yes 14:23:35 BartvanLeeuwen has joined #dwbp 14:23:36 phila: End of this month? 14:23:38 BernadetteLoscio: Yes 14:23:45 Phila: put the open issues in the document, like this one. 14:23:54 BernadetteLoscio: We are working on it. 14:24:16 phila: I'm trying to encourage you to publish something even though there is more work to do. We need another snapshot out to get feedback. 14:24:27 ...We are headed toward Candidate Rec stage in 2 months time. 14:24:28 Data Usage Vocabulary 14:24:29 BernadetteLoscio: Okay 14:24:36 topic: updates on data usage vocabulary 14:24:41 present+ BartvanLeeuwen 14:25:02 https://www.w3.org/2013/dwbp/wiki/images/c/ce/Duv-citations-research.pdf 14:25:02 ericstephan: I put this link on the agenda Update on Dataset Usage https://www.w3.org/2013/dwbp/wiki/images/c/ce/Duv-citations-research.pdf 14:25:12 Present+ Caroline 14:25:13 ...Sorry, it's a slow download 14:25:46 ...I'll wait just a couple minutes while it's downloading (for all of you) — and talk about the Data usage part of the vocabulary 14:25:56 ...BernadetteLoscio and I have resolved this AM we need the working group's input 14:26:11 q? 14:26:11 ...To do that, we have to put issues into the document so you can see where we're struggling. 14:26:15 ...And give us your ideas. 14:26:37 ...There is another part where external folks are working in the climate community (NASA and universities) have a tool called Tool Match, which seems up our alley 14:26:52 ...While it's focused on geospatial, it may give us some ideas on how to direct our efforts on the DUV 14:26:54 q? 14:27:29 ...Next part is the presentation. Last 2 weeks, I appreciate everyone bearing with me on Data citations. 14:27:38 ...It's a challenging problem, how to get the citations model right. 14:28:00 ...I was grappling with the issue that there are a lot of different solutions, challenges, ontologies, vocabularies... 14:28:08 ...Most people think about the Info model. [slide 1] 14:28:21 ...I'm highlighting the MLA, APA and Chicago Manual styles, the three main ones. 14:28:43 ...I've been using the Purdue Online Writing Lab as a resource (logo on slide), because I didn't just want to study about mental models for any type of citation— 14:28:51 ...We care about citations for data on the Web. 14:28:54 ...[Slide 2] 14:29:08 ...Re constructing knowledge models... [Minecraft slide] 14:29:24 ...You have lots of tools with different emphases. I've been looking for the best solution for us. 14:29:29 ...[Slide 3] 14:29:44 ...Is there some level of synchronisation possible, to go from the information model to the knowledge model? 14:30:03 ...You've got a consumer who cites, on the Web, a dataset from a journal article. 14:30:20 ...We have to have a link to that, or we'll only be building knowledge models and not reaching out to the greater community 14:30:40 ...We've got a publisher who creates a metadata citation for data on the Web, or 14:30:42 q? 14:30:53 ...citing a technical document associated with the data. 14:30:56 ...[next slide] 14:31:12 ...Re digital libraries... I've found there is a core electronic document data model. 14:31:20 ...There are different styles that extend that model 14:31:31 ...Around that, you have the vocabularies. SPAR ontologies, Dublin Core, etc. 14:31:50 ...Beyond the vocabularies, you have the Force11 community, and the other non-semweb vocabs 14:32:00 ...You have StructureID. Bib-JSON 14:32:21 ...Because we're looking at open data on the Web and not just semantic data, that's useful. 14:32:42 ...I know we're focusing on URIs as identifiers, but there are legacy datasets that use other identifiers. 14:32:50 ...If they have those, we have to bring those along too. 14:33:10 ...Outside that, whatever we put together for a data model, we include principles from Force11 and BPs... 14:33:21 ...And then there is Interrelated content, which is what you do with the citation 14:33:26 ...And there are ontologies for that. 14:33:42 ...It helped me separate in my mind everything out there, and the correlation between the info and the knowledge models. 14:33:46 ...[Next slide] 14:33:56 ...From the digital librarians... 14:34:00 ...This is the core citation model 14:34:11 ...Only thing we added: the Citation creator 14:34:31 ...There were a few that jumped out at me. Sometimes the publisher, creator and distributor might be broken out 14:34:34 ...[next slide] 14:35:08 ...Based on the previous slide with the basic elements, we have right now in the model DUV-CitationAct, we recommend it includes the properties that support the attributes here. 14:35:16 ...This is up for discussion... did we pick the best properties? 14:35:46 ...Also, if something is published on the Web, sometimes you have authors who are a foaf:agent, sometimes foaf:organisation, sometimes foaf:project 14:35:57 q? 14:36:07 ...The role of the distributor, whoever makes the data accessible on the web... we're talking about the relationship between that and the dataset. 14:36:17 ...We're proposing we go with the basic citation model. 14:36:36 ...Then: we're aligned with the digital librarian community. Got feedback from Purdue. 14:36:47 ...Through this, I've learned which communities we need to get to validate this. 14:36:56 q? 14:37:05 yaso: Thank you for the update. Comments? 14:37:11 phila: I do, but I know we don't have much time 14:37:28 ...Grateful to Eric for that huge amount of work. I need to sit down and send questions on email. 14:37:32 http://www.w3.org/TR/vocab-dqv/ 14:37:33 topic: Data Quality Vocabulary 14:37:53 riccardoAlbertoni: First a little discussion on the update in the document. 14:38:08 ...This week, Antoine changed the data document, updating it according to the decision we made in the last call. 14:38:28 -> http://w3c.github.io/dwbp/vocab-dqg.html DQV 14:38:39 ...I think that the most important thing is that we now have an example to show how to associate all the high-quality certifications for a dataset. 14:38:42 http://w3c.github.io/dwbp/vocab-dqg.html#express-that-a-dataset-received-an-odi-certificate 14:38:54 ...This is an example. http://w3c.github.io/dwbp/vocab-dqg.html#express-that-a-dataset-received-an-odi-certificate 14:39:23 ... Beside small changes on the document, we have 2 discussions pending. 14:39:30 ...We are waiting for people behind the scenes. 14:39:40 ...1) How to encode SLA in a quality policy? 14:39:55 ...Yesterday, Nandana sent examples to the editors. We are considering them and hope to add them to the doc soon. 14:40:23 ...2) Re metrics dimensions categories, is this a concrete class or abstract class? 14:40:39 ...I want to apologise. @@@ contacted us editors last week, and we haven't had time yet to answer. 14:41:01 ...I'd like to move on to concrete discussion about issues now, unless there are questions? 14:41:05 q? 14:41:29 s/@@@/Jeremy/ 14:41:32 [no questions] 14:41:35 issue-202 14:41:35 issue-202 -- Relation between dqv, iso 19115/19157 and geodcat-ap -- open 14:41:35 http://www.w3.org/2013/dwbp/track/issues/202 14:41:39 riccardoAlbertoni: Let's start with issue 202 14:41:56 ...Which was generated by Andrea Perrego. 14:42:19 ...Issue: relationship between the vocab, an ISO standard, the INSPIRE directive and a profile of DCAT 14:42:35 ...Perrego suggested some possible requirements to consider. 14:42:56 ...In the DQV, we are already saying that a dataset conforms to a standard, we have a specific property in the class for doing that. 14:43:24 ...Andrea is asking if we would like to consider also to express that a dataset is not conformant to a standard. Or that it hasn't yet been evaluated against a standard. 14:43:32 ...Yesterday I emailed about this 14:43:44 q+ 14:43:55 ...My position: we should consider to add the support in DQV to express that a dataset is not conformant to a standard. 14:44:08 ...But I'm not sure if it makes sense to say that it has not yet been evaluated against a standard. 14:44:14 ...So, any comments? 14:44:18 q? 14:44:22 ack phila 14:44:23 ack phila 14:44:52 phila: The thing about DCAT-AP and GeoDCAT-AP is that they are in increasing use, the European Data Portal is being launched next week which demands DCAT-AP 14:45:01 ...I get hung up on "what is the subject of the triples." 14:45:26 ...If I have a dataset of bus stops, the dataset doesn't conform to GeoDCAT-AP, but the metadata about the data may conform. 14:45:38 peter has joined #dwbp 14:45:45 present+ peter 14:45:52 ...You'll need a property that says, "This dataset has metadata that is conformant to this standard [like GeoDCAT-AP] 14:45:55 ..." 14:45:56 ex:hasMetadataConformantTo 14:46:11 riccardoAlbertoni: That is a good suggestion 14:46:30 ...It's hard to say if this is in the scope for DQV. It could be. 14:47:08 ...We are trying to model the quality of datasets. The fact that the dataset is compliant to DCAT-AP, which is basically a vocabulary... so it is not a standard? 14:47:20 phila: The European Commission wouldn't agree that it isn't a standard. 14:47:30 riccardoAlbertoni: I guess there are plenty of standards. 14:47:40 ...I wonder if this kind of statement should be captured by our vocabulary or not. 14:47:44 q+ 14:47:54 phila: I think it tells you something about the process, how the data was created. 14:48:12 ...It tells you the organisation that created this data has taken the trouble to create metadata according to this standard. 14:48:14 q+ 14:48:18 there is an RDA - related metadata to metadata link issue: http://www.rda-jsc.org/sites/all/files/6JSC-ALA-45-CCC-response.pdf 14:48:36 ...It lets you trust the data further. 14:48:57 riccardoAlbertoni: I get that. I wonder if the property you were suggesting could be a sub-property of dc:conformsTo? 14:49:02 ...Shall we open an issue? 14:49:08 phila: Was hoping to help you close an issue 14:49:26 riccardoAlbertoni: This is a good suggestion, but I think it's not helping to close the issue. 14:49:34 ...I'm happy you pointed this out. 14:49:37 ack l 14:49:38 ack lauf 14:49:39 q? 14:49:52 ack hadleybeeman 14:49:57 ops 14:50:00 ack laufer 14:50:11 laufer: About the issue of seeing or not if the datasets conforms to a standard: 14:50:23 ...I want to ask, what is the model we are assuming for quality? A closed world, or an open world? 14:50:37 ...I think we have to assert that the quality of a dataset is in a closed world. 14:50:43 riccardoAlbertoni: I tend to agree 14:50:49 it should be closed world 14:50:59 ...In most cases, they are working with a closed world assumption. Depends on the community. 14:51:15 laufer: I think it's difficult to assert all the things that a dataset is not. 14:51:25 hadleybeeman: That's profound 14:51:41 riccardoAlbertoni: You are saying there is difficulties in expressing this statement, but you would find it useful to express it? 14:52:07 laufer: I don't know. I think we have to define what are the assertions about quality that our vocabulary will enable. 14:52:20 ...So, one can assert that a dataset is conforment to a standard. 14:52:35 ...But it seems a strange thing to assert to what the dataset is not conferment. 14:52:59 ...If you don't assert that it IS conformant, then we can conclude that it isn't conforment. 14:53:07 q+ 14:53:25 q- 14:53:27 riccardoAlbertoni: The point is that Andrea is point out that these kinds of needs are required in some domains, like geographical domain. 14:53:28 q+ 14:53:37 ...Where there is a huge amount of open data. 14:54:09 ...I think we should take into consideration the possibility that saying that one dataset is not conformant to a standard. But I don't think "not evaluated yet" is useful 14:54:33 ...And may make the management of metadata more difficult 14:54:49 laufer: If you don't have any assertion about a standard, we can conclude...nothing? 14:54:53 riccardoAlbertoni: Yes, nothing. 14:55:12 ...Because some people will work in an open-world assumption. Others in the closed-world assumption. We can't presume. 14:55:29 ...I'm not sure; this is an open discussion 14:55:33 ack hadleybeeman 14:55:50 hadleybeeman: I wanted to scroll back to talking about the metadata being conformant to a standard 14:56:07 ... If I'm combining datasets, that's what I want to know. That then makes it easy to know what I can do with it 14:56:15 +1 to hadleybeeman 14:56:21 ... So +1 for that being a user need 14:56:40 riccardoAlbertoni: Okay, I appreciate that.
