14:06:16 <PhilA2> Topic: DCAT
14:06:22 <PhilA2> Current version at
14:06:54 <olyerickson> Q's for DCAT: 
14:06:57 <olyerickson> 1. Stable? 
14:07:06 <olyerickson> 2. What it will take for DCAT to be stable? 
14:07:16 <cygri>
14:07:31 <olyerickson> cygri: Will recap
14:07:35 <cygri>
14:07:44 <olyerickson> ... see pages linked above
14:07:57 <olyerickson> ... esp. use cases DCAT is designed to address
14:08:26 <olyerickson> ... history: Emerged from work at DERI
14:08:41 <PhilA2> scribe: olyerickson
14:08:52 <olyerickson> ... based on existing data catalogs incl
14:09:08 <PhilA2> zakim, room for 2 more?
14:09:08 <Zakim> I don't understand your question, PhilA2.
14:09:14 <olyerickson> ... DERI compared sites, tried to capture "common core"
14:09:23 <olyerickson> ... moved work into eGov IG
14:09:42 <olyerickson> ... Weekly ccalls, input, review of use cases
14:09:51 <PhilA2> zakim, how many ports available now?
14:09:51 <Zakim> on Mon Nov 28 09:09:00 2011 I see overbooked, overbooked 30 minutes later, and overbooked 60 minutes later
14:10:04 <olyerickson> ... Have seen increase in adoption
14:10:55 <PhilA2> cygri: Lists several existing users of DCAT (UK, ES etc.)
14:11:12 <PhilA2> ... used by OKFN for federated catalogue etc
14:11:27 <rreck> i can drop and let hadley join
14:11:29 <PhilA2> .. progress on spec hasn't kept pace wtih implementation
14:11:46 <rreck> im just a lurker
14:11:50 <hadleybeeman> Thanks, rreck— but no worries.  I can catch up later.
14:12:35 <PhilA2> cygri: As for how stable it is? Since we have given the work to the GLD, it's as stable as this community wants it to be
14:12:47 <PhilA2> ... if it becomes a Rec then it needs to go through the process
14:12:55 <PhilA2> ... open to feedback from the community and so on
14:13:31 <PhilA2> ... there would be voices along the way saying that X, Y and Z is missing/shouldn't be there and so on
14:13:47 <PhilA2> ... personal speculation - the core of DCAT is nothing new but Dublin Core
14:13:56 <olyerickson> ... regarding stability, depends on influences at this point (adoption => stable, input => improve it) 
14:14:03 <PhilA2> ... vast majority of properties from DC, SKOS and FOAF - they are completely stable
14:14:15 <PhilA2> scribe: PhilA2
14:14:29 <PhilA2> cygri: DCAT assembles existing properties and recommends they're used
14:14:49 <PhilA2> ... DCAT only adds a limited number of fairly simple things beyond these exitsing properties
14:14:59 <PhilA2> .. only a few extra ones not found in DC etc.
14:15:22 <PhilA2> ... may or may not be relevance to otehr catalogues
14:15:33 <olyerickson> ... Handle of additional properties
14:15:44 <olyerickson> s/Handle/Handful/
14:15:51 <PhilA2> ... catalogue 'Distribution' etc. and a few classes/conectors
14:16:22 <olyerickson> ... Introduces new classes...."no brainer" ... reeeeally straighforward
14:16:33 <PhilA2> ... Catalogue record may be a little less obvious as right
14:16:49 <PhilA2> ... but dataset and distribution shouldn't cvhange as you see them everywhere
14:16:54 <olyerickson> ... DCAT reflects structure/org seen in most catalogs
14:17:11 <PhilA2> ... has some conventions and bits of vocab to deal with different distributions of the datasets
14:17:32 <olyerickson> ... describes not only metadata but also HOW TO ACCESS
14:17:47 <PhilA2> scribe: olyerickson
14:17:59 <olyerickson> ... a bit more complicated than it might appear
14:18:10 <olyerickson> ... are different distributions the same, different?
14:18:21 <olyerickson> ... what is a "download?" an "API?" etc
14:18:38 <olyerickson> ... Current DCAT version is a "reasonable" draft of a design
14:18:47 <olyerickson> ... but it can be improved
14:19:07 <olyerickson> ... e.g. how to classify distributions, what are the properties on a distribution, etc
14:19:28 <olyerickson> ... summary: this is cygri's take on where DCAT makes a contribution
14:19:34 <MacTed> MacTed has joined #gld
14:19:51 <olyerickson> ... cygri would like to see: GLD produce a doc that is "in line" with current DCAT docs
14:20:08 <olyerickson> ... need more than vocab ref, but also an application/implementation guide
14:20:32 <olyerickson> ... perhaps use cases/requirements (depends on interpretation of GLD charter)
14:21:05 <olyerickson> ... cygri would like to see vocab ref doc to be produced ASAP
14:21:18 <olyerickson> ... need colunteers
14:21:30 <olyerickson> ... cygri would love to, but can't
14:21:48 <olyerickson> John Erickson: I can co-edit but not solo-edit 
14:22:38 <olyerickson> ... cygri's perceived identification w/ DCAT might have slowed down progress
14:23:03 <olyerickson> ... Welcomes others to pick it up and take it through The Process(tm)
14:23:08 <fadmaa> I am glad to co-edit as well
14:23:26 <BenediktKaempgen> q+
14:23:36 <PhilA2> ack BenediktKaempgen
14:23:42 <olyerickson> PhilA: please use Q+ for questions
14:23:55 <olyerickson> Benedikt: What is the relation between DCAT and Void, etc
14:24:25 <olyerickson> cygri: TBH, they have different core focii
14:24:45 <olyerickson> ... void is metadata for RDF datasets
14:24:56 <olyerickson> ... DCAT is about any datasets
14:25:14 <olyerickson> ... both have been developed independently 
14:25:35 <olyerickson> ... void cand dcat are different projects, diofferent use cases
14:26:00 <olyerickson> ... void is about different distribution of a DCAT dataset
14:26:23 <olyerickson> ... not sure where the best place is to write this up
14:26:27 <cygri> q?
14:26:34 <Martín Álvarez> s/diofferent/different
14:27:01 <olyerickson> yes!
14:27:32 <olyerickson> PhilA: Proposes that he and olyerickson work together to get docs into "working draft" format
14:27:43 <olyerickson> ... there is a process but
14:28:08 <olyerickson> ... given the existing drafts, there are steps that we should get past fairly quickly
14:28:25 <olyerickson> ... but PhilA might be in cloud cookie land
14:28:28 <stasinos> stasinos has joined #gld
14:28:58 <olyerickson> ... given that, a working draft produced ca Xmas, candidate draft not long after
14:29:29 <olyerickson> ... TWC RPI IOGDS will be aligned with DCATp proposal shortly
14:29:59 <olyerickson> ... So: candidate recommendation stage not long away...npt a drawn-out process at this point
14:30:19 <olyerickson> cygri: Big advantage that so much work has already gone into this
14:30:37 <olyerickson> ... we are not starting from scratch
14:31:05 <olyerickson> PhilA: Also will serve as a sign of GLD WG progress
14:31:22 <olyerickson> Topic: ADMS
14:31:50 <olyerickson> Introducing Makx Dekkers
14:31:59 <PhilA2> ADMS = Asset Description Metadata Schema
14:32:27 <olyerickson> ... "Interoperability Assets"
14:32:34 <PhilA2> Current draft of ADMS is in a PDF at
14:32:42 <olyerickson> For background in Makx see:
14:33:06 <olyerickson> ... DCAT could be an interoperability asset
14:33:12 <PhilA2> ADMS designed to describe code lsist, specifications etc. as well as datasets in the DCAT sense
14:33:25 <olyerickson> ... ADMS is about finding common way to describe such assets
14:33:41 <olyerickson> ... ADMS starts with defining conceptual model
14:33:57 <olyerickson> ... closely follows how DCAT looks at things
14:34:16 <olyerickson> ... that's because it's a "no brainer" ;) 
14:34:36 <olyerickson> ... first round: "conceptual model"
14:35:03 <olyerickson> ... examining existing vocabs, "picking and chosing" properties and relationships
14:35:24 <olyerickson> ... challenge: implementing as both RDF vocab and XML schema (ugh...)
14:35:28 <PhilA2> me, Makx and Andrea Perego of JRC (cf. INSPIRE) already looking at using DCAT as basis for ADMS classes and properties
14:35:52 <olyerickson> ... classes, entities, properties, relationships
14:36:17 <olyerickson> ... Second part of document: identifying controlled vocabs that require agreement
14:36:25 <olyerickson> ... e.g. asset types
14:36:32 <olyerickson> ... files formats
14:36:34 <olyerickson> ... status
14:36:37 <olyerickson> ... etc
14:37:19 <olyerickson> ... ADMS provides model with classes that is consistent with DCAT... trying to not invent new vocab terms
14:37:52 <olyerickson> ... trying to create bettwe way of linking information provided in one env. with info in another
14:38:04 <olyerickson> ... agressive timeline (next week!)
14:38:35 <olyerickson> ... reminder: this is the first stagge; WG draft next week, published for public comment early next week
14:38:39 <olyerickson> (year)
14:39:04 <olyerickson> ... after pilot phase, expected to re-visit
14:39:27 <olyerickson> ... looking to align ADMS work with DCAT work (existing and moving forward)
14:39:45 <olyerickson> PhilA: ADMS provides another example of implementation
14:40:08 <olyerickson> ... EU will say, "when you publish pub. information, you *will* use ADMS"
14:40:25 <olyerickson> ... everything is headed in the right direction
14:40:35 <olyerickson> ... thus far, no resistance to using DCAT
14:40:50 <olyerickson> ... so far, no bias against DCAT
14:41:05 <olyerickson> ... Looks like more evidence that DCAT is useful et all
14:41:21 <olyerickson> @PhilA my pleasure ;) 
14:41:46 <olyerickson> PhilA: ADMS timeline is agressive but will help move things along
14:42:02 <olyerickson> ... W3C publishing moratorium
14:42:22 <olyerickson> q+ 
14:42:31 <olyerickson> zakim, unmute me.
14:42:31 <Zakim> olyerickson should no longer be muted
14:42:32 <PhilA2> ack olyerickson
14:42:42 <PhilA2> olyerickson: Extremely exciting
14:43:25 <PhilA2> olyerickson: Glad that work should help with W3C process
14:43:49 <PhilA2> olyerickson: some concern over speed, getting unfinished business into DCAT
14:43:59 <atemezin> @Olyerickson:--it is difficult to follow you on the phone...
14:44:05 <PhilA2> ... getting some of the things that should logically be with DCAT
14:44:17 <olyerickson> sorry
14:44:32 <Zakim> - +90700006aacc
14:44:40 <cygri> q+
14:44:47 <PhilA2> olyerickson: concerned about getting last minyute changes into DCAT
14:44:57 <PhilA2> ... don'think it's much of a prob but is Primary concern
14:45:07 <PhilA2> ... things like dct:language
14:45:10 <PhilA2> ack cygri
14:45:14 <olyerickson> zakim, mute me. 
14:45:14 <Zakim> olyerickson should now be muted
14:45:26 <PhilA2> cygri: responding to John
14:45:33 <Zakim> + +34.00.0.aadd
14:45:46 <olyerickson> cygri: given the timeline, focus the 1sr working draft on what's already there
14:45:55 <olyerickson> ... don't get into changing things
14:45:56 <PhilA2> ... given the time line, might make sense FPWD focus on what's already there without too much work on what might change in future
14:46:02 <olyerickson> ... olyerickson: makes sense!
14:46:15 <PhilA2> cygri: if there's only 2-3 weeks then that might be all that we can do
14:46:17 <PhilA2> q+
14:46:22 <olyerickson> ... cygri: simply getting it into W3C style will be enough of a challenge
14:46:38 <olyerickson> ... also, remember it is the 1st public working draft
14:46:51 <olyerickson> ... no time for additions/modifications
14:47:06 <olyerickson> ... then it will go through the W3C "machine: 
14:47:19 <olyerickson> ... as it draws attention, it will get feedback
14:47:29 <PhilA2> ack me
14:47:30 <olyerickson> ... purpose is to but a flag in the ground
14:47:36 <olyerickson> +1 to that, thanks!
14:48:01 <olyerickson> PhilA: In no way will ADMS or other work shortcut the W3C process
14:48:27 <olyerickson> ... *if* we are inundated with feedback, we will still follow the W3C process
14:49:05 <olyerickson> ... ADMS needs an "indication" of what's coming, doesn't require/depend on that
14:49:12 <olyerickson> +1 PhilA thanks
14:49:35 <olyerickson> PhilA: Summary: ADMS not trying to replace etc DCAT. more about support
14:50:14 <olyerickson> PhilA: Do the people on phone need calls? 
14:50:46 <olyerickson> cygri: not sure if dedicated calls needed
14:50:52 <olyerickson> ... sees the advantages
14:51:18 <olyerickson> ... but still some searching in main GLD call
14:51:29 <olyerickson> ... at the moment, overload GLD call
14:51:44 <olyerickson> +1 to using GLD call bandwidth for this untilw e get kicked out
14:52:19 <BenediktKaempgen> q+
14:52:25 <olyerickson> ... also concerned about DCAT work being taken out of GLD
14:52:31 <PhilA2> ack BenediktKaempgen
14:53:20 <cygri> cygri: no very strong opinion either way
14:53:34 <olyerickson> BenediktKaempgen: Could have DCAT work discussed in task forces we expect to break out of GLD
14:53:59 <olyerickson> ... there will be community directory, standard vocabs, etc
14:54:18 <olyerickson> PhilA: Hearing a concensus (I agree with what they said BTW)
14:54:54 <atemezin> +1 to what @Benedikt said..
14:54:54 <olyerickson> ... of the Chairs feel the weekly calls are being overloaded, then it would be sensible to take them into separate calls
14:55:02 <olyerickson> @PhilA nope
14:55:30 <olyerickson> zakim, unmute me.
14:55:30 <Zakim> olyerickson should no longer be muted
