Onto-what? Everything you (n)ever wanted to know about ontologies or were too embarrassed to ask

This presentation, entitled "Onto-what? Everything you (n)ever wanted to know about ontologies or were too embarrassed to ask", was prepared for and presented virtually at the SciLifeLab Data Management Seminar Series on 15 October 2025. The presentation provides an accessible introduction to biomedical ontologies and is aimed at non-technical data management professionals and scientists in biomedical fields. It addresses some common misconceptions around ontologies, illustrated with domain-relevant use cases, then provides an overview of ontology-related resources and tooling, from introductory background and learning materials, to discovery services, to ontology annotation and editing tools. The recording is available on the SciLifeLab YouTube channel: https://www.youtube.com/watch?v=4nPEebjCY0c SciLifeLab Data Management seminar series is an event series by the SciLifeLab Data Centre and the NBIS joint Data Management team.
