New Revision: 1160332
URL: http://svn.apache.org/viewvc?rev=1160332&view=rev
Log:
Few steps on STANBOL-185.
* The path of a reasoning service can be configured via OSGi console
* Added a asImmutableSet() method to the ReasoningServiceManager to provide an
immutable set of services (for utility, example in a template to iterate the
list of available services)
* Added owlapi and jena modules to the web in pom.xml
* Created a new resource ReasoningServiceTaskResource, to start understanding
how to bind rest requests to reasoning services in a smart way. A basic try
have been done get() method.
* An initial writer for Jena Model have been added.
