More Details
Description
OWLViz is designed to be used with the Protege-OWL editor. It enables class hierarchies in an OWL Ontology to be viewed and incrementally navigated, allowing comparison of the asserted class hierarchy and the inferred class hierarchy. OWLViz integrates with the Protege-OWL editor, using the same color scheme so that primitive and defined classes can be distinguished, computed changes to the class hierarchy may be clearly seen, and inconsistent concepts are highlighted in red. OWLViz has the facility to save both the asserted and inferred views of the class hierarchy to various concrete graphics formats including PNG, JPEG, and SVG.
Installation
OWLViz is bundled with the "full" installation of Protege. After you have installed Protege, there are two additional steps you need to perform for this plugin to work properly:
- Download and install a recent version of Graphviz, which is a free, open source graph visualization software from AT&T Research. Mac users please see Troubleshooting below.
- Protege will make an educated guess about where to find graphviz depending on your operating system, but if it does not get it right you will need to configure this yourself:
- Protege3.x and Protege4.0 (pre build 105) on the OWLViz tab, click the Options button to bring up the Options dialog. On the Layout Options panel, specify the path to the location of the DOT executable (dot.exe). The Options dialog will look something like the following, after performing this step:
- Protege4.x (build 105 onwards) these settings have moved into the OWLViz preferences panel. Again, specify the path to the dot executable in the appropriate place.
Documentation
All of the OWLViz documentation is located on the CO-ODE Website. The OWLVizGuide is somewhat outdated, but still very helpful. Also, you may refer to the home pages for the OWLViz plugin for additional information:
Home page for build 17 (Protege3.x): http://www.co-ode.org/downloads/owlviz/.
Home page for build 18 (Protege4.x): http://code.google.com/p/co-ode-owl-plugins/wiki/OWLViz.
Level of Support
OWLViz build 17, which is distributed with Protege-OWL 3.3.1 is no longer under active development. If you need help with this version of OWLViz, please try posting your questions on the protege-owl mailing list, and someone from the Protege user community may be able to help you.
OWLViz build 18, which is bundled with Protege-OWL 4.0 is under active development and all comments, suggestions, and/or feature requests are appreciated! Please post questions and requests on the p4-feedback mailing list.
Troubleshooting
Many people report the following error the first time they try to use the OWLViz plugin:
This error message indicates that
a) you need to install Graphviz and/or
b) you need to tell OWLViz where you installed Graphviz.
Instructions for doing both of these things is located above in the "Installation" section.
Mac users - finding the right version of Graphviz
The current status of Graphviz for the Mac OS is very unclear.
The latest binaries they point to directly (the pixelglow implementation) no longer contain the dot application required by OWLViz. According to their download page this distribution is out of date and not maintained.
Install version 2.14 from one of their alternatives and point to that instead (it gets installed in /usr/local/graphviz-2.14/). This contains the necessary binaries in the bin/ folder.
