Semantic Web and Reasoner

[buells]

Hello Group,

I git the problem, that i need a reasoner written in C# or with an
simple interface to C#. My problem is, that all of the programs i find
are written in java?? i don't want to port it myself, but i think since
the semantic web is on its way to get out of the universities, there
must be some tools to deal with owl semantics in C# !! The only things
i find are rdf tools, but the semantics provided by rdf is not enough
for me (e.g. i wan to define an inverse Object Property, but this isn't
possible with rdf, but with owl).

So my question is: Are there any OWL parser/reasoner out there, which
could be used for free ??

Thx in advance,

Nils Drews

Check out this that I have been looking for a while. Its OWL lite, but it's
good.

Otherwise check if you can find something else here:

I also have the same problem; may I ask if you already have implemented
code in c# using pellet? I've the suspect it's just thought for java...
thanks in advance for the help!

No, not yet. We are doing modelling and design using Pellet at this moment.
If all's well, we need to integrate Pellet with C# if no other solutions
come around.
There are many good bridges to do the integration, if J# can't beat it.

Well, I tried to convert the Jena Engine to C# using the ikvmc out of
the Mono Project, and it worked rather well, but there were still a few
Exceptions, which i couldn't track down yet (and I don't want to).

The other idea I tried is the DIG Interface, which is available for
Java (again) but converts without any problems to C# using ikvmc. This
way i don't have to deal with the whole engine, but with the rather
small interface and i get an abstraktion layer over the reasoner.

I won't follow that trail now, but when i continue this part of my
work, i think this is the most practicable way to go.
