Back to reading about RDF, it is
I have been reading about OWL 2 for ten minutes now and I still have no idea what it's for
So it seems that OWL 2 is essentially "a standard library of utilities for expressing complex RDF relationships" and if they'd actually *said* that anywhere it would've saved me an awful lot of time
(and spoons, for that matter)
datatype D-entailment, conjunctions of simple atomic sentences in first-order logic, merging the two singleton subgraphs of the three-node graph, ... 
@joepie91 It's not RDF, but recent HL7 data structures probably satisfy your other criteria.
@riley Unfortunately it's specifically RDF stuff that I'm trying to learn :/
@joepie91 Does RDFa count? Then I got Google which uses some RDFa for some of the visualizations in the search https://developers.google.com/search/docs/appearance/structured-data/dataset?hl=en
Other than that I am not aware of one. There are some bigger medial and university things around that use it. Also the EU uses it for their datasets afaik.
@joepie91@social.pixie.town I too have been searching for something like this for fucking years.
The gnome tracker media indexer is one of the best examples I've seen because there's a little known standard for embedding rdf data into mpeg (and other containers) that it can use aside from id3 tags, so even though virtually nothing uses it you can kinda see what's going on.
I've been thinking about using rdf for a project but it's such an impenetrable standard that I'm turned off 😕
@joepie91 iirc, the json-ld module for nodejs has a function to convert json-ld into rdf. Shove a toot into that maybe?
Does anyone have a link to a real-world complex example of RDF / linked data that isn't just Wikidata? Preferably something that shows how related data from multiple sources (with some overlap) would be handled.
