Re: EasierRDF

Hi Melvin,

What I mean is that nobody (slightly tongue-in-cheek) cares about what's IN the ontology, descriptions, labels, OWL.  People use schema.org<http://schema.org> for the name spacing and the SEO.  People care about name spacing, they dont care about inferencing.  It's hard to even find wide spread examples of inferencing used in the wild

                Can you please elaborate on where these properties “name”, “born”, “spouse” are coming from? Are they exhaustively listed somewhere? Or can any publisher simply use their “own” properties? If so, how do clients know what keys to use to get the name, birthdate, spouse, .. of objects from different publishers? (“born” is not as meaningful as you may think – it could refer to place of birth too, for instance) Or, what if some publishers want to be more fine-grained (first name, initials, last name)? Would clients need to utilize NLP methods?

I believe you’re equating the utility of ontologies with inferencing (correct me if I’m wrong), but IMO their core purpose is precisely to define shared vocabularies for concepts like these (first/last name, birthdate, birthplace, ..) (A.k.a., a “shared conceptualization of a domain”.). Software clients, programmed to recognize a set of well-known vocabularies, can understand all content published using those vocabularies.

Re the discussion around “ex:” – of course, if everyone uses their own vocabulary this will defeat the whole purpose. I don’t think that was the takeaway of that example (it rather concerned the Turtle vs. JSON syntax).

JSON keys OTOH are simply JSON keys and can be compared character for character

So are RDF terms :-) A client that is pre-programmed with a known set of vocabularies can compare the found RDF terms character-by-character to their programmed vocabularies, and then do something useful with the data.

Dear community,

I came across the project https://github.com/w3c/EasierRDF. I think it is a good idea to have a look at RDF and the challenges it has. I'm struggling with the use, because the work that is necessary to make systems interoperable by understanding ontologies, formatting the data, extending ontologies, writing queries, etc, is huge! I am a big fan of graph databases and the ease of using Neo4j, Cypher, plain json and writing converters between readable json formats is so much faster and developer friendly. Queries in Cypher are intuitively and can be understood on sight. I am also looking at Solid and I find the approach of data pods extremely interesting and relevant, but the structure is so overwhelming and overcomplicated that I start losing faith in this. Since the project EasierRDF is started, I guess others struggle with the same? Are there some major advantages of using RDF and Sparql over Neo4j and Cypher? We could do linked data with Json-ld and Neo4j?

I came to realize than in 15 years of heavy RDF use, the useful 10% is what I use 90% of the time

You might want to look at this one-pager which tries to take some of the useful bits of RDF (@id @type @context) and add it to JSON

https://linkedobjects.org/

It is for beginners getting started, and has an upgrade path to JSON-LD and full RDF, for those that want it.  It's also compatible with plain old JSON, without needing the overhead of creating and maintaining ontologies (which let's face it, almost no one does or cares about today)

Use cases and libraries are yet to be built out, but hopefully some food for thought


Thanks

Kind regards,
Frederik

Hi Frederik,

You are asking an excellent question, and I think the community as a
whole would benefit from discussing it on a public list, both to get
more viewpoints and to expose your question to other existing RDF users.
  Would you be willing to post your question to the public
semantic-web@w3.org<mailto:semantic-web@w3.org> list?

Thanks,
David Booth
