OWL/RDFS and Marmotta

[Diego Benna <di...@gmail.com>]

Dear developers of Apache Marmotta,
I want ask information about ontologies in Marmotta. Ontologies are managed? I
can upload files owl/rdfs and import files rdf consistent? I can do checks
on imported files, or load any file rdf? What can I do with ontologies owl /
rdfs in Marmotta?
Thanks as always for your kindness
Diego

KiWi, the triple store used by Marmotta, provided a built-in rule-based 
reasoner for enabling such semantics on top of your triples. Further 
details at the web site:

http://marmotta.incubator.apache.org/kiwi/reasoner.html

So, for instance, if you want to have RDFS, you'd need to add the rules 
that implemented such semantics. In the wiki you can find some sample 
programs:

http://wiki.apache.org/marmotta/Reasoner/ExamplePrograms

Although the syntax looks a bit unfriendly at first, actually it's quite 
easy to write rules in that language.

In the former wiki you can also find some more information we still did 
not manage to migrate to Marmotta:

Hope this helps.

Cheers,
