RE: Standardizing N3/Rules, was Re: ✅ Literals as subjects Re: Toward easier RDF: a proposal

Hi Nathan, Doerthe, and all,

I’d be quite interested in contributing (to the best of my ability) – I’ve been working in the health informatics domain for some time where rules are quite important to realize clinical decision support. I’ve done some work (cue the self-citations!) in computerizing and benchmarking OWL2 RL [0], optimizing RETE for semantic reasoning [1], and using (DL) rules for illness self-management [2] and assisted ambient living [3, 4]. In the health domain, semantic technologies are already widely employed for computerizing biomedical knowledge (just look at BioPortal) and we seem to be way past the bootstrapping phase.

Merging two threads together

However, if I should be able to make statements like this about strings, why not any data type? Why not an entire RDF graph, like { { <foo> a <bar> . } published “2014-02-28T00:00:00Z”^^xsd:dateTIme .  } ?

Very useful, +1
Well that is N3.

Standardizing N3 is I think beyond the scope of David’s plea o make rdf more approachable. But is a good idea also.

Logic. We have worked with N3 for years now and there are several reasons why I believe that it should be standardized ...

Call to action: who would support and/or join a W3C community group around an N3 rule language?

So far,
- Doerthe Arndt
- Jos De Roo
- Ruben Verborgh
- Nathan Rixham

Anybody else?
