Hugh, I agree with Juan that these are questions for step 9:-) However, one data point: as far as I can see and understand, the Property Graph model does not put the kind of emphasis RDF does on the usage of URI-s for the nodes and links. You can, of course, use a URI for the identification of nodes, but I would expect that the practice is to add a URL as 'label' to a node or a link. The discussions on PG<->RDF at the workshop concentrated on ways to add such labels to RDF predicates, but you are right that the role of URL-s must be looked at as well… Cheers Ivan > On 11 Mar 2019, at 23:03, Hugh Glaser <hugh@glasers.org <mailto:hugh@glasers.org>> wrote: > > Hi Juan, > Many thanks. > I know this is the SemWeb group; although the thing that interests me is Linked Data, which is sort of related. > I don't want to cross-post, so I'll just ask here. > > So was there anyone at the workshop interested in Linked Data? > > Specifically how LD-style URIs relate to PGs and Neo4J? > That is, PGs relating to the core LD stuff: resolvable and globally addressable IDs. > I see little or no mention of IDs, URIs or anything like that, and any implications that would have for the PG technologies. > > Is no-one interested in that? > I would have asked in person, but sadly I was not chosen to be invited ;-) - I'm guessing because such interests are not widely shared (I never saw the criteria for choosing invitees). > > Or maybe everyone understands it all, and it isn't a big issue - if so, can anyone point my at a simple exposition of the issues please? > > Best > Hugh > >> On 8 Mar 2019, at 18:42, Juan Sequeda <juanfederico@gmail.com <mailto:juanfederico@gmail.com>> wrote: >> >> All, >> >> I wrote my trip report on the W3C Graph Data workshop: http://www.juansequeda.com/blog/2019/03/08/w3c-graph-data-workshop-trip-report/ <http://www.juansequeda.com/blog/2019/03/08/w3c-graph-data-workshop-trip-report/> >> >> It was a successful event!
