Persistent storage #1039

Closed luisenriqueramos1977 closed 2 years ago

luisenriqueramos1977 commented 2 years ago

Dear All,

I wonder if there is a persistent storage for owl API?, I mean a DB or triple store?, because I checked this tutorial: http://syllabus.cs.manchester.ac.uk/pgt/2021/COMP62342/introduction-owl-api-msc.pdf

and I only found reading and writing to files, not to dbs.

Best regards

Luis Ramos

That's correct, OWLAPI doesn't include a lot of support for triple stores. There is a RioMemoryTripleSource that can read from a RDF4J source, which allows connection to a triple store, but this is not commonly used. You might take a look at ONTAPI, which implements the OWLAPI api package on top of Apache Jena and so might offer triple store access via that library.
