Class OBOFlatFileRenderer

java.lang.Object

org.semanticweb.owlapi.io.AbstractOWLRenderer

org.coode.owlapi.obo.renderer.OBOFlatFileRenderer

All Implemented Interfaces:

OBOExceptionHandler, org.semanticweb.owlapi.io.OWLRenderer

public class OBOFlatFileRenderer
extends org.semanticweb.owlapi.io.AbstractOWLRenderer
implements OBOExceptionHandler

Renders OBO 1.2 flat file format. OBO 1.2 is a subset of OWL, so a rendering of an arbitrary OWL ontology may be incomplete in OBO. Several features are currently not implemented: - Exception handling for unsupported constructs - these are currently reported in stderr - axiom annotations (these might be serialisable as inline comments - although OBO parsers provide no guarantees these will be roundtripped) - anonymous classes/properties - it is not clear what this means in OBO - datatype restrictions - namespace and derived tags for relationships etc - it is not clear what this means in OBO - preservation of ordering on roundtripping exercises - Stanzas are ordered (classes, obj/data props then instances) - Entities are ordered by ID in each Stanza type - OBO tags are ordered WRT the OBO specifications Additional points: - cardinality is expressed as an '=' separated tag value pair in [1] and underspecified in [2]. OBOEdit 2 does not parse this (at the time of writing) so this has been changed to standard TVP syntax - OBO 1.2 currently specifies pairwise disjointness which this renderer follows so files may get large - Exceptions are caught along the way and then wrapped in an OBOStorageIncompleteException which is thrown after serialisation ends References: [1] http://www.cs.man.ac.uk/~horrocks/obo/ [2] http://www.geneontology.org/GO.format.obo-1_2.shtml
