Hi,
Unfortunately these features are not available anymore.
There is a new way to perform these types of computing. It consists in associating a plugin to the SPARQL interpreter in such a way that : each time a solution of the query is found or a property path is identified, a plugin callback function is called in order to perform specific processing, e.g. network analysis operation.
The plugin must implement the ResultListener interface (fr.inria.edelweiss.kgram.event ; kgram project)
The main functions to be implemented are :
public boolean process(Path path)
public boolean process(Environment env)
Best regards

Thanks, I'll look into the Java API.
Hi,
I managed to get Corese working with basic SPARQL queries. I have a couple of questions about the extended SPARQL language:
param[...]
construct described in the paper Analysis of a Real Online Social Network Using Semantic Web Frameworks. Does this work in the current version of Corese? Or do I have to "simulate" this by generating the queries for all parameters?I've found
group by any
queries in the tests (1, 2), but I couldn't get it working:This throws an exception:
(Without the
group by any
line, it's fine).Thanks, Gabor
