11:05:11 <fsasaki> topic: intro
11:05:28 <fsasaki> christian: welcome to the call, agenda has been sent out
11:05:46 <fsasaki> .. will look at action points, then use cases
11:05:52 <fsasaki> ... start with new members intro
11:06:00 <fsasaki> sergey: working for wolters kluwer
11:06:19 <fsasaki> ... I am solution architect, involved in semantic search implementation
11:06:38 <fsasaki> axel: at Univ. economics & business in Vienna
11:06:51 <fsasaki> ... doing semantic web research for 10-12 years
11:07:07 <fsasaki> ... was involved in paper with christian and felix in joint paper that also helped to create this CG
11:07:33 <fsasaki> ... involved in creation of XSParql, technology to combine RDF and XML processing
11:07:53 <fsasaki> christoph: from univ. bonn, Fraunhofer IAIS, several years exprience of translating XML > RDF
11:08:08 <fsasaki> ... want to develop something that works for as many XML input formats as possible
11:08:23 <fsasaki> ... deploying this in natural language analyis and industrie 4.0 exchange formats
11:08:31 <fsasaki> johnS: working for mark logic
11:08:44 <fsasaki> ... implementing semantic features in mark logic in the last years
11:08:56 <fsasaki> ... seeing interesting use cases around the combined use of XML and RDF
11:09:10 <clange> Links to software mentioned previously: http://xsparql.deri.org/, https://github.com/EIS-Bonn/krextor
11:09:18 <fsasaki> ... working on technology to reflect RDF data out of the document, without any invisible change
11:09:32 <fsasaki> ... looking for collaboration related to XML and RDF
11:09:49 <fsasaki> bernat: working at @@@, small start up
11:10:17 <fsasaki> ... working on a new presentation of the bible, for combining the information we need combination of XML and RDF processing
11:10:23 <AxelPolleres> AxelPolleres has joined #rax
11:10:25 <fsasaki> ... output format is also some kind of XML
11:10:34 <fsasaki> .... so we need roundtripping between XML and RDF
11:11:05 <fsasaki> topic: action points
11:11:29 <fsasaki> christian: want to gather informaton about existing tools etc.
11:11:43 <fsasaki> ... florent created github organization to gather the info
11:11:44 <svasil> svasil has joined #rax
11:11:56 <fsasaki> ... now we need somebody who can add the info
11:13:16 <fsasaki> felix: propose to have 1-2 admin people and then everybody allow to add content
11:13:33 <fsasaki> christian: so florent + I will be admin, others can add stuff. That is a starting points
11:14:05 <AxelPolleres> shall we use proposals in the W3C way, i.e. PROPOSED: … ?
11:14:10 <fsasaki> action: florent to allow everbody to add content to the rax github repo and have himself and christian as admin
11:14:23 <fsasaki> topic: topics to cover
11:14:44 <fsasaki> christian: the group desription says: we want to cover concrete things
11:14:50 <fsasaki> .. chairs got two inputs
11:15:03 <fsasaki> ... both were addressing the data transformation back and forth (roundtripping)
11:15:39 <fsasaki> ... we need to make process as smooth as possible
11:15:55 <fsasaki> ... transformation question will always arise
11:15:55 <AxelPolleres> data transformation … side note: interesting issue is the one concerning blank nodes in scripts (which currently re-surfaces in the SPARQL-dev list, BTW) anybody having an eye on that here?
11:16:23 <labra> labra has joined #rax
11:16:24 <fsasaki> ... another input yesterday from Martynas, see https://lists.w3.org/Archives/Public/public-rax/2016Jun/0008.html
11:16:38 <fsasaki> about an RDF/XML extension
11:16:53 <AxelPolleres> RDF/XML in quads, interesting … what about JSON-LD is JSON-LD already quad/namedgraph ready?
11:17:00 <fsasaki> ... also the XML Prague paper http://archive.xmlprague.cz/2016/files/xmlprague-2016-proceedings.pdf#page=133
11:17:08 <AxelPolleres> q+
11:17:16 <fsasaki> ack ax
11:17:17 <jpcs1> q+
11:17:46 <fsasaki> axel: about the quad in RDF/XML or json-ld etc. - is that in scope too?
11:17:52 <fsasaki> christian: json is in scope too
11:18:19 <fsasaki> axel: a lot of discussion going on in the sparql-dev list on sparql features
11:18:26 <fsasaki> ... core of issue has to do with blank nodes
11:18:55 <RRSAgent> I have made the request to generate http://www.w3.org/2016/06/24-rax-minutes.html fsasaki
11:19:08 <fsasaki> ... also something we may look into
11:20:18 <AxelPolleres> on this EXISTS blank node issue, here a link to the discussion… https://lists.w3.org/Archives/Public/public-sparql-dev/2016AprJun/0039.html
11:20:18 <fsasaki> felix: may make sense to separate in discussion the use cases and tools, because there is a m:n relation between them
11:20:47 <fsasaki> christian: we need another round yet to get more details on the proposals, also collect more information
11:21:04 <fsasaki> ... I will share the input with the group and beyond, and ask them to share input - what they have
11:21:13 <fsasaki> ... concerning tools etc.
11:21:32 <fsasaki> ... we collect that in 10 days and structure that, so that we better know what topics to tackle

11:22:08 <RRSAgent> I have made the request to generate http://www.w3.org/2016/06/24-rax-minutes.html fsasaki
11:23:18 <fsasaki> felix: propose to have a template for use cases and also for tools, to make gathering easier
11:23:37 <fsasaki> christian: makes sense, will provide that tuesday next week - feel free to provide info before
11:23:50 <fsasaki> action: christian to provide use case and tool templates to the group
11:23:51 <fsasaki> topic: aob
11:24:32 <fsasaki> christian: last call we decided that suggestions of new topics / use cases etc. should be shared first with the chairs - but maybe it is better to share directly with the group
11:24:52 <fsasaki> ... the group will not be overwhelmed. so if something comes up you fill out the template and send it to the group
11:25:01 <fsasaki> +1
11:25:07 <philr> +1
11:25:18 <labra> +1
11:25:25 <fsasaki> bernat: can we use github for this?
11:25:52 <fsasaki> christian: yes, part of the process, but for a new idea just sending a mail should be ok
11:25:58 <fsasaki> bernat: ok
11:26:43 <fsasaki> christian: next AOB topic - please promote the group, within your organisation and beyond
11:26:51 <fsasaki> ... see this as a role to do that actively
11:27:34 <fsasaki> christian: promote the group at conferences etc., so that the network grows
11:28:02 <fsasaki> ... last point: BDVA meeting, input from felix
11:28:59 <clange> q+
11:29:26 <clange> I'll be at EDF, CU there. (Do we have a list of EDF participants?)
11:29:54 <philr> I will also be there
11:30:36 <fsasaki> ack jp
11:31:16 <fsasaki> john: on areas of work - for mark logic documents and XML and HTML are still the "forgotten part" of RDF
11:31:29 <fsasaki> ... RDF was designed to be built on top of docs
11:31:39 <fsasaki> ... so need to take the link between docs and RDF into account
11:31:56 <fsasaki> ... there is a fair amount of work to be done to augment sparql
11:32:04 <clange> (With RDFa a bit of this view came back into mainstream)
11:32:25 <fsasaki> ... often people want to find documents looking at RDF, or the other way round
11:32:49 <fsasaki> felix: so retrieval scenario involving RDF and XML at the same time?
11:33:12 <fsasaki> john: a friend used the fact that there was RDFa markup in HTML - at the same time he processed parts of the document content
11:33:26 <fsasaki> ... you need a system that can handle both RDF and docs at the same time
11:33:35 <clange> I'm also very much interested in this and have done previous research in the field of combining documents and RDF; cf. e.g. http://www.semantic-web-journal.net/content/ontologies-and-languages-representing-mathematical-knowledge-semantic-web (application domain was STEM)
11:33:48 <fsasaki> ... you don't want to be forced to add (RDFa) labels to tables - you just want to be able to fetch the tables
11:34:01 <fsasaki> ack cl
11:34:16 <fsasaki> john, very interesting use case.
11:34:42 <fsasaki> christoph: at fraunhofer we are involved in the industrial data space initiatve, e.g. helping companies to exchange data
11:35:00 <fsasaki> ... in this context we are looking into industrie 4.0, there are a lot of XML standards
11:35:01 <fsasaki> q+
11:35:33 <fsasaki> christioph: we are working on re-implementing some of the standards in RDF - that needs translations between XML and RDF
11:37:42 <fsasaki> ack chr
11:37:44 <fsasaki> ack fs
11:38:05 <fsasaki> felix: preservation of XML workflows was emphasized by john - I think that is very important
11:38:16 <clange> Industrial Data and Service Space: http://www.industrialdataspace.org/ (secure information exchange, digitisation, data sovereignty). Currently a German national project, but there's a movement to scale it to the EU level
11:38:17 <fsasaki> christoph: sure
11:38:26 <bernat_kallo> q+
11:38:39 <fsasaki> john: depending on how we design things, an approach can fulfil multiple purposes
11:38:42 <fsasaki> ack ber
11:39:03 <fsasaki> bernat: a third perspective on translation: creating a document from an RDF data store
11:39:18 <fsasaki> ... e.g. generate HTML from RDF data - this is also part of RDF to XML or SVG etc. conversion
11:39:55 <fsasaki> christian: thanks to all, next call will be in two weeks time, and then 2 p.m. CEST
11:40:05 <fsasaki> ... today was an exception
11:40:19 <fsasaki> ... minutes will be made available, I will send the template next week
11:40:40 <fsasaki> ... have a nice weekend, adjourned
