Questions about working with Fuseki
Hello,
Little by little I am getting things running as they are intended. I got Fuseki to run, and I can update and query through its web interface. Mine is here:
http://128.48.204.195:3030/sparql.jsp
I have a few confusion points:
1) While I am able to get it running through the web interface that I pointed to above, what url can I use to send queries and updates via http?
2) If I need to use a reasoner, how can I add it? I understand that JENA is part of Fuseki. But how do I configure a reasoner (pellet) to reason over my model before it gets queried? Or how is that kind of thing meant to work within this architecture?
3) If I need a reasoner, than will I have to install Java and write code to call the JENA API? Or is it possible to just do it all via Fuseki?
Thanks,
Alex

I suggest you get an assembler description of setup you want working in
a normal Java program, then use that assembler with Fuseki.
Tim's answer on answers.semanticweb.com points to the documentation.

Hi,
Is the assembler option that you suggest a way to write your own inference rules? It wouldn't seem like a good way to go for someone with my experience level in such issues. I think I would be happy to just have Fuseki invoke some off the shelf reasoning.
Is that possible? And how do I set it up?
Thanks,Alex

Assemblers and include --desc to start the server

Not if the above works for you.
