1 BugVISor: A DAML Debugging Tool Mitch Kokar Versatile Information Systems, Inc.
2 ConsVISor: consistency checking ConsVISor Checks axioms of DAML Displays results (errors and hints) ConsVISor is available for use at:
3 ConsVISor - example
4 NumIDMessage 1:0034 The classes and were declared to be disjoint, but they both contain
5 BugVISor BugVISor would extend ConsVISor by Annotating errors and warnings found by ConsVISor using a DAML ontology (BugOntology.daml) Reasoning about errors and warnings Finding and displaying the cause of errors and warnings
6 BugVISor - context Ontology Or Annotated Source DAML Axioms ConsVISor Bug Locations Explanations BugVISor Errors DAML Bug Ontology
7 BugVISor – proposed features Built on DAML philosophy Use a Bug Ontology in DAML Automatically annotate errors Reason about errors Would grow together with DAML
8 WOW! Factors Would make finding errors easier, simpler, faster Would make DAML more user-friendly and attractive Bottom Line: INCREASED PRODUCTIVITY of ontology developers and annotators IMPROVED QUALITY of ontologies and annotations
9 WOW! Factors: Example We tested one of the ontologies on daml.org ConsVISor found 76 errors 75 were related to a single typo daml+ont instead of daml+oil It was not that easy to find the error BugVISor would help!
