**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 (Adding or removing axioms). An OPPL script (See bellow or test.oppl) defines a query to be performed against the ontology, and some actions 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 a given 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). 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.

  This is the OPPL script provided in the bundle, test.oppl (Variables start with ?): 

  ?whole:CLASS,
  ?part:CLASS
  SELECT
  ?part SubClassOf part_of some ?whole WHERE ?part != Nothing
  BEGIN
  ADD ?part SubClassOf part_of only ?whole
  END;
