Graph Widget Tutorial OWL

Graph Widget Tutorial for OWL Ontologies

This tutorial assumes a basic working knowledge of Protege-OWL.

Example ontology

For the purposes of this tutorial, we will use a simplified version of a clinical trial ontology developed by Ravi Shankar at BMIR. For the most part, the concepts in this ontology are self-explanatory. To follow are some definitions of class names that may be less obvious at first glance:

• Aliquot – a measured portion of a sample taken for analysis
• Assay – a laboratory test to find and measure the amount of a specific substance
• Specimen_Protocol – protocol for handling a specimen in a clinical trial

In order to follow along with the tutorial in Protege-OWL, please download a copy of the example clinical trial ontology.
