Graphical Schema Editing for Stardog OWL/RDF Databases using OWLGrEd/S
نویسندگان
چکیده
The developers of StarDog OWL/RDF DBMS have pioneered a new use of OWL as a schema language for RDF databases. This is achieved by adding integrity constraints (IC), also expressed in OWL syntax, to the traditional “open-world” OWL axioms. The new database paradigm requires a suitable visual schema editor. We propose here a two-level approach for integrated visual UML-style editing of extended OWL+IC ontologies: (i) introduce the notion of ontology splitter that can be used in conjunction with any OWL editor, and (ii) offer a custom graphical notation for axiom level annotations on the basis of compact UML-style OWL ontology editor OWLGrEd.

متن کاملOWLGrEd: a UML Style Graphical Editor for OWL
There have been many attempts to visualize OWL ontologies but none of them is considered completely satisfactory and this is still an open problem. We propose a UML style graphical editor for OWL which not only visualizes ontologies using extended UML class diagram notation but also provides ontology editing facilities unavailable in most of the other tools. Moreover, the editor contains additi...
متن کاملAdvanced Ontology Visualization with OWLGrEd
Intuitive ontology visualization is a key for their learning, exchange, as well as their usage in conceptual modeling. OWLGrEd is a visual tool for compact graphical UML-style rendering and editing of OWL 2.0 ontologies. Here we introduce into OWLGrEd visualization annotations that allow defining custom visual presentations of ontology entities on the basis of annotations attached to these enti...
