Meeting minutes
Announcements and newcomers
pchampin: no announcements
Open actions
<pchampin> https://
pchampin: one open actions on the RDF-star repo
<pchampin> https://
gkellogg: all updated
pchampin: it was about the test suites
gkellogg: accomplished and Andy found some other issues that were cleared up as well
<pchampin> https://
pchampin: there are also actions related to the charter
… no progress on these yet
… also two open PRs
… since no additional feedback on them, they will be merged
Publicity of RDF-star
pchampin: rationale for this iterm: there is a lot going on on the mailing list
… most of it is about possible limitations of RDF-star
… much noise about the parts that are missing
… but not much about the benefits and what we have achieved
olaf: I see it the same way as pchampin
… the mailing list may give the impression that we have failed
… some discussions on twitter may give the same impression
… what can we do to put more weight on the benefits of what we have achieved?
… also, it is hard to follow/respond to those long discussions
AndyS: parts of these discussion wander off into directions where RDF-star would not be a direct solution anyway
… dedicated ontologies would be more appropriate
… UK released such an ontology (4D ontology, not using RDF-star)
… called IES (Information Exchange Standard)
gkellogg: the RDF-star got somehow hijacked by RDF wishlists
gkellogg: unfortunately, the discussion/list of RDF-star got high jacked
<rivettp> Here's a public presentation about IES https://
AndyS: maybe too early, but we could gather examples of succesful use of RDF-star
olaf: some people are claiming that RDF-star is not good for anything
pchampin: Andy's idea about gathering success stories of RDF-star could be useful
ora: what could be done about it?
… AWS has a database blog
… which has a fairly large readership
… maybe a blog post there?
… about what RDF-star is
+1
pchampin: that would be great
AndyS: solicit more implementation reports
… Ontotext?
pchampin: they may wait for the WG?
… reach out to the people who were involved in the early days of our task force
<AndyS> [off] rivettp - great! (Ian is the IES editor)
rivettp: more examples needed
… not so much examples that focus on edge cases (marriage)
… RDF-star gives more rope to hang yourself
inverse properties may be problematic
pchampin: the inverse was mentioned in one of the github issues
<pchampin> https://
AndyS: impl.report from RDF4J ?
gkellogg: discussions on the list went off because of the complexity of modelling
… ongoing are still questions about the fundamentals of RDF-star
pchampin: there were also comments by Pat
Doerthe: I wasn't that active in the discussions b/c of the Christmas break
… we may say what the relationship to Property Graphs is.
ora: maybe reach out to Pat again?
<gkellogg> +1
pchampin: I agree to Doerthe's comment about the Property Graphs
… present a direct mapping
<pchampin> https://
pchampin: also the design patterns for n-ary relations in RDF may deserve an update
… that document may contain cases in which RDF-star is a good means and other in which it is not
… back to PGs: the direct mapping would have an indirection
AndyS: Sounds all like working on a background for the WG
pchampin: perhaps these things may be listed as deliverables for the WG -- although there is already a long list of deliverables
AndyS: some write-up of the issue of transparency may be helpful
rivettp: encourage others in the W3C community to go beyond RDF-star
… probably outside the scope of this group here
… establish best practices around using RDF-star
olaf: to summarize: 1) reach out to implementors
<AndyS> [off] I'll talk to RDF4J
olaf: I can reach out to Ontotext and Stardog
… 2) AWS blog post
… 3) add more examples, collect them on the CG blog
pchampin: any example for point 3?
AndyS: I recently came about an example in the context of DBpedia
Action: olaf to reach out to Ontotext and Stardog
Action: pchampin to reach out to Corese
Action: AndyS to reach out to RDF4J
Action: ora to publish a post on the AWS blog
Action: ora to reach out to Pat Hayes
olaf: the examples we publish on the CG blog need to be carefully designed
Action: pchampin to write a CG blog post about different kinds of occurrences
<rivettp> I'm interested in examples
WG chartering
pchampin: not much to add on the topic of the charter at this point
