    The OWL API has a very good design and works as a connector for several applications of the Semantic Web community.

    I think there is a bug in the OWL API 3.4. When I run the LoadingOntologies example from "owlapi.svn.sourceforge.net", I get this error: Exception in thread "main" org.semanticweb.owlapi.io.OWLOntologyInputSourceException: java.io.FileNotFoundException: \tmp\pizza.owl (系统找不到指定的文件。) at org.semanticweb.owlapi.io.FileDocumentSource.getInputStream(FileDocumentSource.java:88) at org.semanticweb.owlapi.io.FileDocumentSource.getReader(FileDocumentSource.java:98) at org.semanticweb.owlapi.io.AbstractOWLParser.getInputSource(AbstractOWLParser.java:199) at org.coode.owlapi.rdfxml.parser.RDFXMLParser.parse(RDFXMLParser.java:119) at uk.ac.manchester.cs.owl.owlapi.ParsableOWLOntologyFactory.loadOWLOntology(ParsableOWLOntologyFactory.java:210) at uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntology(OWLOntologyManagerImpl.java:720) at uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntologyFromOntologyDocument(OWLOntologyManagerImpl.java:668) at uk.ac.manchester.cs.owl.owlapi.OWLOntologyManagerImpl.loadOntologyFromOntologyDocument(OWLOntologyManagerImpl.java:679) at org.coode.owlapi.examples.LoadingOntologies.main(LoadingOntologies.java:81) Caused by: java.io.FileNotFoundException: \tmp\pizza.owl (系统找不到指定的文件。) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(FileInputStream.java:106) at org.semanticweb.owlapi.io.FileDocumentSource.getInputStream(FileDocumentSource.java:86) ... 8 more Java Result: 1

    This is the cleanest of all the APIs I have used so far. Wonderfully designed to provide the essential utility classes for general use case scenarios. Thanks a lot guys!

    Nice and Easy to use.

    The OWL-API is an indispensable component of my ontology development workflows and is integral to the running of a number of web sites with which I am involved, including Virtual Fly Brain.
