WebProtégé. The Web-based version of Protégé offers users and their collaborators the opportunity to share and edit ontologies online, much like a Google doc. Here we see the Ontology for Parasite Lifecycle (OPL), an ontology developed by a community of scientists who investigate malaria, toxoplasmosis, and other diseases caused by eukaryotic pathogens (Parikh et al., 2012). In the left-hand pane, the user has selected the class blood. The middle pane shows the properties of the selected class. The right-most pane reveals an audit trail and a threaded discussion regarding the modeling of this entity.
