**About OPPL-Galaxy**

  OPPL-Galaxy can be used to execute an OPPL script against an ontology, generating a new ontology. OPPL (Ontology Pre Processor Language) is a high level scripting language, based in the Manchester OWL Syntax, to automate the manipulation of an ontology. An OPPL script (See test.oppl) defines a query to be performed against the ontology, and some actions (Adding or removing axioms) that affect the entities that will be retrieved. Those entities can be named or defined by a variable. OPPL is a powerful method for defining and executing modelling patterns that are repeated in an ontology, saving time and effort.  

**Formats**

  OPPL-Galaxy uses the OWL API, and therefore it can load any ontology format that such API is able to load: OBO flat file, OWL (RDF/XML, OWL/XML, Functional, Manchester), turtle, and KRSS. The available output formats are OBO flat file and OWL (RDF/XML).

**Usage**

  An ontology and an OPPL file are needed (test.owl and test.oppl can be used as samples, both available in the bundle). Load both with Get Data >> Upload File from your computer. 

  Then execute the OPPL file against the OWL file with Ontology Pre Processor Language >> Execute an OPPL file against an OWL file. A new output ontology will be generated.

  In case the loaded ontology includes OWL imports, a file that maps the imported ontologies' URIs to actual physical URIs is needed. The file (See the file test_URI_mappings provided in the bundle) follows the convention URI-tab-physical URI:
  
  http://purl.obolibrary.org/obo/CHEBI_ONTOLOGY_chebi_ontology	/home/pik/UPM/OPPL_galaxy/oppl/OPPL/chebi.owl

  http://purl.obolibrary.org/obo/UBERON_uberon	/home/pik/UPM/OPPL_galaxy/oppl/OPPL/cell.owl

  The output ontology can be OBO or OWL (RDF/XML).
 
  The inferred subsumption axioms can be added to the output ontology as asserted axioms. 

  The reasoner can be Pellet or HermiT. Sometimes, if an execution fails it can be fixed by using a different reasoner.
