I am new to ontology development and want to learn how to create my first OWL ontology using Protégé. Please find the 'Protégé Pizza Tutorial' and identify if it is updated, and then find the 'Ontology Development 101' guide and state its purpose. Also, find the 'Brief introduction to ontologies' by Robert Stevens and explain its content.
Navigate to the Protégé wiki main page (protegewiki.stanford.edu). Scroll down to the 'Tutorials and Getting Started' section. Locate the 'Michael DeBellis's updated Protégé Pizza Tutorial' and confirm if it is explicitly stated as 'updated'. Locate the 'Ontology Development 101: A Guide to creating your first ontolog...' link and describe its purpose based on the link text or surrounding content. Locate the 'Brief introduction to ontologies' by Robert Stevens link and describe its content based on the link text or surrounding content.
