Also, in New Entity Settings in Web Protégé, if needed (assuming you aren't using UUIDs) change the IRI suffix to whatever format you were using in Protégé. The difference is that in the Ontology prefixes tab there will be an extra / or # character which you need in order to correctly map to an individual entity.

Note: make sure to copy from the mappings in the Ontology prefixes tab not from the Ontology IRI at the top of the Active Ontology tab. Change that to the IRI that is the IRI for your ontology defined in Protégé. In New Entity Settings you will see that the default IRI prefix is. In Web Protégé go to Project>Settings (Project is a link in the upper left corner). When you upload an ontology into Web Protégé, rather than pick up the default new entity IRI from the preferences (which I had set to user supplied name) it defaults to UUIDs.īoth of these are easy to fix. When you upload an ontology into Web Protégé, rather than pick up the default ontology IRI from your file, Web Protégé assigns the IRI Prefix: The most common example is rdfs:label but there are many more. This makes your ontology more reusable and there are various tools that will look for these properties and know what to do with them. I think it's a good idea to re-use the entities from these common vocabularies rather than creating entities with the same name that are in your ontology. Protg is compatible with all of the major. Using Protg Desktop or WebProtg you can generate complex, shareable ontologies for your research outputs in order to make them easier to understand for your collaborators and anyone looking to build on your findings. Often we'll have properties (e.g., identifier) and classes (e.g., Agent) that already exist in commonly reused vocabularies ( Dublin Core and FOAF respectively). Protg is a powerful tool for preparing your data for the Semantic Web. This is a practice I've started to use and I encourage others to consider. Also, note that in the UNSDG ontology I added a prefix for Dublin Core (dc). For example, if you go to the Annotation Properties tab you will see that all of those properties have prefixes because they come from different ontologies, specifically rdfs and owl. However, you still have the option of using a prefix to refer to entities in other ontologies. Feel free to make adjustments to suit your needs. That way when you refer to entities in your ontology you don't have to use a prefix. This guide describes one possible approach to configuring the Eclipse Platform for working with the Protege Desktop source code. Protégé generates a default mapping from the empty prefix to your ontology IRI. The Protégé platform supports two main ways of modeling ontologies via the Protege-Frames and Protege-OWL editors.On the left is every prefix your ontology uses and then next to the prefix is the IRI that it maps to. Further, Protege can be extended by way of a plug-in architecture and a Java-based Application Programming Interface (API) for building knowledge-based tools and applications. Protege can be customized to provide domain-friendly support for creating knowledge models and entering data. At its core, Protégé implements a rich set of knowledge-modeling structures and actions that support the creation, visualization, and manipulation of ontologies in various representation formats. Protégé is a free, open-source platform that provides a growing user community with a suite of tools to construct domain models and knowledge-based applications with ontologies.
