13:12:26 <kurzum> created by one of my colleagues in leipzg
13:13:10 <bhyland> dwood: Asked when the older W3C working group co-chairs should roll out?
13:13:53 <bhyland> phila: Explained he'd like to see some seasoned members remain involved to the tune of 1 hour/mos to join the coordination call, if possible.
13:14:56 <bhyland> Arnaud: Discussed LDP WG updates ...
13:16:04 <bhyland> Option is to stay in CR in perpetuity vs. go to last call again. Issues with getting time commitment for an implementation ...
13:16:12 <phila> http://www.w3.org/TR/ldp/#ldpic is the feature at risk in the new LCWD
13:16:59 <bhyland> Arnaud: Just published LDP Paging & went to LC
13:17:09 <davidwood> davidwood has joined #dacg
13:18:36 <davidwood> Arnaud, The Callimachus Project should have an implementation test report to you within 3-4 weeks. Apologies for the delay.
13:18:43 <bhyland> Also, LD Patch, a patch format so you can patch for defining expressing a sequence of ops for LD resources. Used for HTTP PATCH method, see https://dvcs.w3.org/hg/ldpwg/raw-file/ldpatch/ldpatch.html

13:19:57 <bhyland> Editor's Draft is available for review. Arnaud said it is too early to tell if there will be sufficient public feedback.
13:21:14 <bhyland> Topic: LDP - next generation
13:22:03 <bhyland> Phila: Access Control is anticipated to be a 'charterable' topic for a future LDP Group.
13:22:41 <bhyland> Phila: Is soliciting input from other W3C WG chairs to see if there is synergy / interest.
13:23:22 <davidwood> q+
13:23:28 <phila> ack davidwood
13:24:02 <bhyland> Phila: The bar to starting a new W3C working group is high, so we have to make sure we do sufficient research & make sure there is sufficient interest.
13:25:05 <bhyland> DavidWood: The topic of Access Control is critically important but inextricably linked to a topic where everyone has a 'favorite dog' in the race.
13:25:39 <bhyland> … What I like about the LDP spec(s) is the simplicity of the recommendations, avoiding the Access Control 'hairball'.

13:26:00 <Zakim> the conference code is 3224 (tel:+1.617.761.6200 sip:zakim@voip.w3.org), ericP
13:26:16 <bhyland> Arnaud: I would prefer to see LDP recommendations be a set of detailed 'modules' that people can select to implement/adopt.
13:26:35 <Zakim> +ericP
13:26:36 <bhyland> Davidwood: So how do you foster interoperability?
13:27:23 <bhyland> Arnaud: Today, people are adopting other means of doing Access Control, yet they are implementing parts of the LDP.
13:28:28 <bhyland> Davidwood: I don't want to take up the time of the DACG's time today to deal with this, but we can offer some concrete input having done an implementation of the real life issues we've faced dealing with Access Control.  It is an important issue.
13:28:38 <bhyland> Topic: CSV Working Group

13:32:23 <kurzum> to annotate publicdata csv files
13:32:33 <bhyland> Topic: Healthcare & Life sciences Interest Group update
13:32:53 <bhyland> RE: Clinical interest group calls, per EricP ...
13:33:09 <bhyland> Group discussing clinical observations ...
13:33:58 <bhyland> Would coordinate with the HCLS Group. Good pairing because people expect respective groups to understand semantic technologies & HL7, respectively.
13:35:20 <bhyland> Topic: Data on the Web Best Practices WG
13:35:30 <bhyland> Has 4 co-chairs but none are on the call today.
13:35:59 <bhyland> Phila: It is going ok, lots of discussion, and working on getting words on paper. We're meeting at TPAC in October 2014.
13:36:12 <bhyland> Topic: Newly forming Data Shapes Working Group
13:36:51 <phila> -> http://www.w3.org/2014/data-shapes/charter Data Shapes Charter
13:36:52 <phila> (proposed)
13:36:53 <bhyland> EricP: on history of Data Shapes Working Group
13:38:01 <bhyland> Desire for RDF data validation/interface definition on SemWeb ...
13:39:11 <bhyland> How do we balance the social issues that balance the diverse interests of those who have invested in different approaches to address interpretation of shapes or optimize SPARQL queries & create UIs.
13:39:23 <phila> -> https://www.w3.org/2002/09/wbs/35125/TPAC2014/registrants TPAC registrants
13:39:45 <bhyland> … If we meet F2F in TPAC and discuss approaches, that would be ideal.
13:40:08 <bhyland> Arnaud: I've been asked to chair & I agreed, but I'm looking for a good strong co-chair
13:40:24 <phila> -> http://www.w3.org/2014/11/TPAC/ Main TPAC page
13:41:05 <bhyland> … We were at this workshop last year (2013) and there were concerns about whether standards should lead or lag specifications.
13:41:50 <bhyland> … The members of the workshop generally were in agreement back in 2013. However, when it came time to charter the working group, there was more contention on the public list.
13:44:45 <bhyland> … We'll see how this pans out. There are companies who are quite far down the road with implementations but we feel going through the W3C process would be beneficial long term.

13:46:27 <bhyland> Topic: Graph Normalization
13:46:34 <danbri> how does this relate to http://json-ld.org/spec/latest/rdf-graph-normalization/ ?
13:46:44 <danbri> "This document outlines an algorithm for normalizing RDF graphs such that these operations can be performed on the normalized graphs."
13:47:16 <bhyland> Phila: During the formation of the Data Shapes WG Charter, there was much humming & hawing around Graph Normalization.
13:47:34 <bhyland> ManuS has proposed what he believes to be a credible solution.
13:47:56 <bhyland> … that he proposed during his recent SemTech 2014 keynote.
13:48:13 <ericP> q+
13:48:19 <phila> ack ericP
13:48:34 <davidwood> I have not found a need for graph normalization, but that doesn't mean there isn't one.
13:48:45 <bhyland> Phila: Is graph normalization central to the Shapes Charter?
13:49:00 <phila> No, it's not in that charter, bhyland
13:49:20 <kurzum> My opinion is, that this is a research issue. Is there a method to do a diff? and decide equality
13:49:38 <bhyland> Correction: Discussion was whether graph normalization *should* be added to the charter?
13:50:41 <ericP> q+ to say that shapes can give you the ordered traversal of a graph which can produce a normalized graph.
13:50:44 <danbri> Shapes is interesting, because it gives an RDF version of the "is this data valid or not?" mechanisms people are familiar from in XML etc.
13:50:51 <phila> ack ericP
13:50:51 <Zakim> ericP, you wanted to say that shapes can give you the ordered traversal of a graph which can produce a normalized graph.
13:50:51 <danbri> RDFS/OWL expressly don't do that.
13:50:59 <bhyland> Kurzum: There are higher priority items to be included in his opinion. Graph normalization may be more suitable as a research topic.
13:51:51 <bhyland> EricP: Described use cases where it would be useful, e.g., ordered traversal of graph.
13:52:03 <Kerstin> I've a very practical need: a good way to represent value sets, e.g. the so called controlled terminiligies drawn fromCDISC / NCIt, see http://kerfors.blogspot.se/2013/10/the-future-of-cdisc-cts.html
13:54:13 <phila> Topic: SEMANTiCS
13:54:15 <bhyland> Topic: reflections from SemTech, SEMANTiCS
13:54:28 <phila> s/Topic: SEMANTiCS//
13:55:16 <bhyland> Kurzum: SEMANTICS is a 10 year old event, started as academic research conference, now moving towards industry engagement.
13:55:45 <bhyland> … Industry is interested in Linked Data, but we need bridges to make it seem more relevant.
13:56:59 <phila> bhyland: Dave and I attended SemTech(Biz) in San Jose
13:57:20 <phila> ... new owner added Biz to emphasise business application
13:57:45 <phila> ... booths with strong Tech had more visitors than the marketing types. Tightly coupled with NoSQL conference
13:58:21 <kurzum> q+
13:58:26 <phila> ... we (3 Round Stones) were next to Cloudera (2 $bn VC funding) and Mongo. Lots of people don't get what a graph is
13:59:18 <phila> davidwood: I'be neen to about half the SemTech events. Didn't think it was too useful for business but it was fun.
13:59:48 <bhyland> davidwood: I previously thought SemTech was more of a conference to connect with my peers, but not really to do 'business'.  In fact, after attending about 5 over the last 10 years, it was a good conference for our company to conduct business.
13:59:54 <phila> ... Can be hard to justify going. This year we decided to sponsor and speak. The crowd has changed. More people interested than used to be the case
14:00:06 <bhyland> … There was more discussion around partnering & commercial work getting done.
