![]() ![]() The course can benefit both beginners with no prior experience of the Protégé toolset and/or ontology development and intermediate users of Protege Desktop or WebProtege. Enrollment is limited to ensure optimal learning experiences.Target audience members include everyone who wishes to develop or enhance their skills for building OWL ontologies using Protégé. The course is taught by members of the Protégé team. Protégé is the most popular and widely used ontology editor in the world with a vibrant community of over 300,000 registered users. During the hands-on portion of the course, participants will learn how to navigate the latest version of the Protégé and WebProtégé toolsets, which support the full OWL 2 standard. The team covers best practices in ontology building and the latest Semantic Web technologies, including OWL 2, RDF and SPARQL.They also cover topics such as collaborative development, and data access and import from different data sources.Most of course is hands-on. 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 Protégé Short Course provides an in-depth introduction to ontology engineering in the Web Ontology Language (OWL). 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. 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). 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. That way when you refer to entities in your ontology you don't have to use a prefix. Protégé generates a default mapping from the empty prefix to your ontology IRI. On the left is every prefix your ontology uses and then next to the prefix is the IRI that it maps to. ![]()
