Part of a joint presentation with Midori Harris comparing OWL (Web Ontology Language) and OBO (Open Biomedical Ontologies) as ontology languages, This presentation concentrates on OWL, Midori Harris presented OBO.
1. OWL: Web Ontology Language An overview Dr. Duncan Hull, Software engineer, EBI Chemoinformatics and Metabolism

11. Who? Ontogenesis 25.02.10 OWL is managed by a Working Group at the W3C http://www.w3.org/2007/OWL/ A large group of people chaired by : http://web.comlab.ox.ac.uk/ian.horrocks/ http://sciencecommons.org/about/whoweare/ruttenberg/ Ian Horrocks, The University of Oxford Alan Ruttenberg, Science Commons

14. Where does OWL fit? Ontogenesis 25.02.10 Class: ChEBI:Acetylsalicylic_acid SubClassOf: ChEBI:Salicyclic_acid, ChEBI:acid-of some ChEBI:Acetylsalicylate, ChEBI:has-role some ChEBI:anti-inflammatory_drug For humans For machines Using existing XML, RDF and OWL tools

16. Ontogenesis 25.02.10 Capulets (Biologists) Like to use OBO Montagues (Computer Scientists) Like to use OWL The Montagues and the Capulets (2004) Carole Goble, Chris Wroe Comparative and Functional Genomics , Vol. 5, No. 8. pp. 623-632. http://dx.doi.org/10.1002/cfg.442
17. Montagues and Capulets Ontogenesis 25.02.10 Montagues (OWL) Capulets (OBO) Generic (“top down”) Specific (“bottom up”) Describe any domain (in theory) : Technology driven Describe biology (in practice) “ Application pull” Focus on automated reasoning using logic Focus on supporting existing users Background in Artificial Intelligence Background in genome annotation (e.g. with Gene Ontology)
18. In an ideal world we could easily “round-trip” OWL and OBO 25.02.10 Without gaining or losing information OBO version 1.2 OWL 2.0
