After having spent some time trying out inferencing of RDF triples using OWL specifications I have concluded that it is very useful and sort of magical, but also super slow (at least in the implementation I’ve been using). I wonder if Datomic and its clones will ever have reasoners...?

Morning, back to work after a week of vacation.

@simongray have you looked at https://github.com/quoll/asami/tree/master/docs

Asami seems really nice for regular applications, but I have to work with RDF and OWL. While Asami is inspired by RDF (Paula has done a lot of RDF work previously, as you probably know already) it doesn’t support RDF directly, let alone OWL and inferencing. In this case, I have to work with RDF and OWL as I’m doing academic work that needs to shared using these existing standards.

So I’m using Apache Jena through Luke Vanderhart’s wrapper, Aristotle

Which I will probably end up forking, since it’s practically abandoned by Luke… :S

We do the same (also fork)

Jena takes me back. Very slow in years gone by (like 2002)

good luck

There is an open source graph / triplestore implemented in Clojure that can deal with sparql

I can find it when I’m back at the keyboard

Found it: https://docs.flur.ee/

Haven’t used it myself

Oh right, I forgot about that. If I didn’t have to also support OWL that could probably be interesting to look further into. Anyway, @borkdude what kind of changes have you guys made to your Aristotle fork? And is it public? If you don’t mind me asking.

[ it's a distributed computing kinda day ]

it's always morning somewhen

https://github.com/mladvladimir/aristotle - not sure what the changes are as I haven't worked on this part a lot, but @mlad.vladimir might be able to explain

Hi @borkdude @simongray, so far, my fork of Aristotle contains a few missing pieces of SPARQL algebra like :left-join , :slice and stuff like graph serialization (currently work on property paths implementation). Is there any specific part Jena lib you’re interested in @simongray?
