**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 efforts.  

**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, or redirect from another Galaxy tool.

  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, OPPL-Galaxy will try to resolve them. 

  The output ontology can be OBO or OWL (RDF/XML).
   
  The reasoner can be Pellet, HermiT FaCT++. Sometimes, if an execution fails it can be fixed by using a different reasoner.
