Passwordless Authentication and Passwordless Security

Identity is everything. Protect it with Duo.

It’s no secret — passwords can be a real headache, both for the people who use them and the people who manage them. Over time, we’ve created hundreds of passwords, it’s easy to lose track of them and they’re easily compromised. Fortunately, passwordless authentication is becoming a feasible reality for many businesses. Duo can help you get there.

    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.

    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!
