Note that a different parameter is used in the URL of WebVOWL in this case («url» instead of «iri»). With this option, the VOWL visualization looks alomost the same whenever it is opened. Here is again an example for the FOAF vocabulary: If the JSON file has been exported using WebVOWL, the VOWL visualization will be restored with the layout and user settings it had before. Alternatively, the generated JSON file can be exported and linked or uploaded.

A stable VOWL visualization can be shared by exporting it to SVG or printing it as a PDF file. Note that the dynamically generated visualizations will look different due to the force-directed layout. For instance, the following URL requests the visualization of the FOAF vocabulary:
If you want to convert a custom ontology another time, simply hit the reload button of your web browser.Ī custom ontology can also be visualized by appending its IRI to the URL of WebVOWL. However, they are cached in the web browser to allow for a more fluent interaction. Note that converted ontologies are neither saved nor cached on the server.
For instance, complex datatypes and some instance level constructs are not supported by WebVOWL at the moment.Ī custom ontology can be visualized by opening the Ontology menu and either entering the IRI of the ontology or uploading the ontology file. Note that WebVOWL is able to visualize most language constructs of OWL 2 but not all of them (and also not all combinations). Run WebVOWL » Old WebVOWL version (beta 0.5.2) as fallback » A Java-based OWL2VOWL converter is provided along with WebVOWL. The VOWL visualizations are automatically generated from JSON files into which the ontologies need to be converted. Interaction techniques allow to explore the ontology and to customize the visualization. It implements the Visual Notation for OWL Ontologies (VOWL) by providing graphical depictions for elements of the Web Ontology Language (OWL) that are combined to a force-directed graph layout representing the ontology. WebVOWL is a web application for the interactive visualization of ontologies. WebVOWL: Web-based Visualization of Ontologies VOWL Specification »
