roll call

checking attendees ...

intro

christian: welcome to the call, agenda has been sent out
... will look at action points, then use cases
... start with new members intro

sergey: working for wolters kluwer
... I am solution architect, involved in semantic search implementation

axel: at Univ. economics & business in Vienna
... doing semantic web research for 10-12 years
... was involved in paper with christian and felix in joint paper that also helped to create this CG
... involved in creation of XSParql, technology to combine RDF and XML processing

christoph: from univ. bonn, Fraunhofer IAIS, several years exprience of translating XML > RDF
... want to develop something that works for as many XML input formats as possible
... deploying this in natural language analyis and industrie 4.0 exchange formats

johnS: working for mark logic
... implementing semantic features in mark logic in the last years
... seeing interesting use cases around the combined use of XML and RDF

<clange> Links to software mentioned previously: http://xsparql.deri.org/, https://github.com/EIS-Bonn/krextor

johnS: working on technology to reflect RDF data out of the document, without any invisible change
... looking for collaboration related to XML and RDF

bernat: working at @@@, small start up
... working on a new presentation of the bible, for combining the information we need combination of XML and RDF processing
... output format is also some kind of XML
... so we need roundtripping between XML and RDF

action points

christian: want to gather informaton about existing tools etc.
... florent created github organization to gather the info
... now we need somebody who can add the info

felix: propose to have 1-2 admin people and then everybody allow to add content

christian: so florent + I will be admin, others can add stuff. That is a starting points

<AxelPolleres> shall we use proposals in the W3C way, i.e. PROPOSED: … ?

<scribe> ACTION: florent to allow everbody to add content to the rax github repo and have himself and christian as admin [recorded in http://www.w3.org/2016/06/24-rax-minutes.html#action01]

topics to cover

christian: the group desription says: we want to cover concrete things
... chairs got two inputs
... both were addressing the data transformation back and forth (roundtripping)
... we need to make process as smooth as possible
... transformation question will always arise

<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?

christian: another input yesterday from Martynas, see https://lists.w3.org/Archives/Public/public-rax/2016Jun/0008.html

about an RDF/XML extension

<AxelPolleres> RDF/XML in quads, interesting … what about JSON-LD is JSON-LD already quad/namedgraph ready?

scribe: also the XML Prague paper http://archive.xmlprague.cz/2016/files/xmlprague-2016-proceedings.pdf#page=133

axel: about the quad in RDF/XML or json-ld etc. - is that in scope too?

christian: json is in scope too

axel: a lot of discussion going on in the sparql-dev list on sparql features
... core of issue has to do with blank nodes
... also something we may look into

<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

felix: may make sense to separate in discussion the use cases and tools, because there is a m:n relation between them

christian: we need another round yet to get more details on the proposals, also collect more information
... I will share the input with the group and beyond, and ask them to share input - what they have
... concerning tools etc.
... we collect that in 10 days and structure that, so that we better know what topics to tackle

felix: propose to have a template for use cases and also for tools, to make gathering easier

christian: makes sense, will provide that tuesday next week - feel free to provide info before

<scribe> ACTION: christian to provide use case and tool templates to the group [recorded in http://www.w3.org/2016/06/24-rax-minutes.html#action02]

aob

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
... the group will not be overwhelmed. so if something comes up you fill out the template and send it to the group

<philr> +1

<labra> +1

bernat: can we use github for this?

christian: yes, part of the process, but for a new idea just sending a mail should be ok

bernat: ok

christian: next AOB topic - please promote the group, within your organisation and beyond
... see this as a role to do that actively
... promote the group at conferences etc., so that the network grows
... last point: BDVA meeting, input from felix

<clange> I'll be at EDF, CU there. (Do we have a list of EDF participants?)

<philr> I will also be there

john: on areas of work - for mark logic documents and XML and HTML are still the "forgotten part" of RDF
... RDF was designed to be built on top of docs
... so need to take the link between docs and RDF into account
... there is a fair amount of work to be done to augment sparql

<clange> (With RDFa a bit of this view came back into mainstream)

john: often people want to find documents looking at RDF, or the other way round

felix: so retrieval scenario involving RDF and XML at the same time?

john: a friend used the fact that there was RDFa markup in HTML - at the same time he processed parts of the document content
... you need a system that can handle both RDF and docs at the same time

<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)

john: you don't want to be forced to add (RDFa) labels to tables - you just want to be able to fetch the tables

john, very interesting use case.

christoph: at fraunhofer we are involved in the industrial data space initiatve, e.g. helping companies to exchange data
... in this context we are looking into industrie 4.0, there are a lot of XML standards

christioph: we are working on re-implementing some of the standards in RDF - that needs translations between XML and RDF

felix: preservation of XML workflows was emphasized by john - I think that is very important

<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

christoph: sure

john: depending on how we design things, an approach can fulfil multiple purposes

bernat: a third perspective on translation: creating a document from an RDF data store
... e.g. generate HTML from RDF data - this is also part of RDF to XML or SVG etc. conversion

christian: thanks to all, next call will be in two weeks time, and then 2 p.m. CEST
... today was an exception
... minutes will be made available, I will send the template next week
... have a nice weekend, adjourned
