Hi Rupert,
I've decided to go on with only enhancer and entityhub; to use fuseki
server for storage and reasoning.
Now my problem is indexing.
I have three main ontologies, two of them are for extracting semantics
from custom CMS components, one of them is just extracting the implicit
semantics in content hierarchy (articles, categories vs) so I'll be able
to implement semantic search. I did a little research and I encountered
[1]. It says, Solr components are independent from Stanbol, but when I
look at the bundles on Osgi console, the solr components are in
org.apache.stanbol.commons.solr package, not in org.apache.commons.solr
package.
Lastly, is there a way to integrate Solr server in stanbol with Fuseki
server?

Hi Umutcan,
The Linked Media Framework [1] tried to build a think like you
described. In this case it was running a Sesame based triple store,
Solr for Semantic Search and Stanbol for enhancing contents all in a
single instance. Was we learned form that was that it makes much more
sense to keep those things separated.
If you want everything in Stanbol I can try to give you some pointers:
Im not the most knowledgeable person on the Ontonet, Reasoning and
Rules component. But AFAIK it uses Clerezza as storage component. So
you can use any triple store that is supported by Clerezza. The most
commonly used one is Jena TDB.
Stanbol also has a very simple SPARQL endpoint typically published
under "/sparql" (http://localhost:8080/sparql) via this you can access
graphs managed by Clerezza. So if you have your RDF data stored as
Clerezza Graphs you should be able to query them using this endpoint.
So if the Ontonet and Reasoning components can use Clerezza to store
results it should be possible to also use the Stanbol server as Sparql
instance. I hope some of the Ontonet people see this and answer this
question
Make sure to use the 1.0.0-SNAPSHOT because 0.12.* still use an older
Clerezza version that does not yet support Clerezza Fastlane [2]

Hi,
I'm trying to implement semantic search for a CMS written in PHP that we use
in my university as a part of my master's thesis.
Ontonet seems to be a good solution for storing and reasoning on instance
and conceptual data. However, as far as I understand from previous
questions, ontonet does not provide a sparql endpoint.
This leaves me at a point where I need to decide if I should use Stanbol
only for semantic lifting and use another triple store provides sparql
endpoint. Another approach in my mind, retrieving ontologies from ontonet
temporarily to a reasoner and storing them back with inferred triples, but I
wonder if there is a simpler way that involves only Stanbol components.
Is there a formal way to integrate external triple stores to Stanbol? Could
you suggest some other solution without an external triple store?
