OpenTox Ontology service

The Ontology service is an implementation of OpenTox Ontology service API.

The Ontology Service does not depend on AMBIT modules, and compiles into a different web application. It currently uses the Jena TDB persistence mechanism, and was initially designed as a proof-of-concept service to illustrate the added value of gathering RDF triples of several remote OpenTox services into the same triple storage and enabling SPARQL queries.

Please note: AMBIT REST web services do not require an Ontology service to be installed. However, some applications like ToxPredict and Bioclipse-OpenTox depend on querying an OpenTox Ontology service.

Currently, the Ontology service is used as a registry of all deployed OpenTox services (both local and remote), and ToxPredict web application retrieves the list of QSAR models via SPARQL query.

Web application archive: ontology.war

Deployment

Copy ontology.war under webapps directory of the servlet container. The application should be accessible at
```
 http://localhost:8080/ontology
```

Configuration

Does not use MySQL database. Uses Jena TDB for persistent storage (file based), which is automatically generated on deploy. The following configuration files can be found under webapps/ontology folder. There are reasonable default values.

WEB-INF/classes/org/opentox/config/config.properties

#tdb or sdb , currently tdb supported only 
persistence=${jena.persistence}
#where to store TDB files. Default is java temporary directory
tdb=THE-PATH-TO-THE-TDB-FOLDER

WEB-INF/classes/org/opentox/config/aa.properties

aa.opensso=URI-OF-OPENTOX-OPENSSO-SERVICE
aa.policy=URI-OF-OPENTOX-POLICY-SERVICE

Models registration

        curl -X POST -d "uri=THE-URI" http://yourhost:8080/ontology -H "subjectid:OPENSSOTOKEN"

Or use the HTML form at the top, paste the URI of the model and click "Submit".
