Question: Can roxi be integrated with existing oxigraph KGs in some way?

[epoz]

On advice from Pieter Colpaert posting the question here:

If I understand it correctly, you are only using OxRDF, but not the storage part of Oxigraph for roxi.
How tricky would it be to integrate roxi with an existing Oxigraph instance? (to add reasoning)
That would be very exciting.

Hi @epoz ,

Thanks for reaching out!

Yes, we do not use the storage and querying layer of Oxigraph in RoXi at this point. The initial version of RoXi built around this functionality of Oxigraph. We left this path as it was not performant enough since we did not have access to oxigraphs internals. We ended up rewriting much of the functionality that was not exposed.
Later I saw that there was an issue on the oxigraph where the creator of oxigraph also said exactly that.

At this point we can pipeline RoXi with Oxigraph, but it is not very efficient doing that as you have a duplication of the triples (in RoXi and in oxigraph).
The best way would be to built reasoning capabilities inside oxigraph, but then oxigraph will need more exposure of its internals. If there is a high request for such capabilities, we can reach out to the creators of oxigraph and see what is possible.

KR,
Pieter
