1. Goal and Status of the OBO Foundry Barry Smith

2. 2 Semantic Web, Moby, wikis, crowd sourcing, NLP, etc.  let a million flowers (and weeds) bloom  to create integration rely on (automatically generated?) post hoc mappings The result is noisy How create broad-coverage semantic annotation systems for biomedicine?

3. Perhaps even deadly 3

4. 4 for science develop high quality annotation resources in a collaborative, community effort creating an evolutionary path towards improvement of terminologies of the sort we find elsewhere in science Foundry alternative:prospective standardization

5. 5

6. 6 what makes GO so wildly successful ?

7. 7 science basis of the GO: trained experts curating peer-reviewed literature different model organism databases employ scientific curators who use the experimental observations reported in the biomedical literature to associate GO terms with gene products in a coordinated way The methodology of annotations

8. 8  cellular locations  molecular functions  biological processes used to annotate the entities represented in the major biochemical databases thereby creating integration across these databases and making them available to semantic search A set of standardized textual descriptions of

9. 9 and also need to extend the GO by engaging ever broader community support for the addition of new terms and for the correction of errors need to extend the methodology to other domains, including clinical domains

10. 10 this requires that we establish common rules governing best practices for creating ontologies and for using these in annotations apply these rules to create a complete suite of orthogonal interoperable biomedical reference ontologies

12. 12 The OBO Foundry http://obofoundry.org/ 2006

13. 13 A prospective standard designed to guarantee interoperability of ontologies from the very start (contrast to: post hoc mapping) established March 2006 12 initial candidate OBO ontologies – focused primarily on basic science domains several being constructed ab initio by influential consortia who have the authority to impose their use on large parts of the relevant communities.

15. 15 OBO Foundry = a subset of OBO ontologies, whose developers have agreed in advance to accept a common set of principles reflecting best practice in ontology development designed to ensure  tight connection to the biomedical basic sciences  compatibility  interoperability, common relations  formal robustness  support for logic-based reasoning The OBO Foundry http://obofoundry.org/

16. 16 CRITERIA  The ontology is OPEN and available to be used by all.  The ontology is in, or can be instantiated in, a COMMON FORMAL LANGUAGE.  The developers of the ontology agree in advance to COLLABORATE with developers of other OBO Foundry ontology where domains overlap. CRITERIA The OBO Foundry http://obofoundry.org/

17. 17 CRITERIA  UPDATE: The developers of each ontology commit to its maintenance in light of scientific advance, and to soliciting community feedback for its improvement.  ORTHOGONALITY: They commit to working with other Foundry members to ensure that, for any particular domain, there is community convergence on a single controlled vocabulary. The OBO Foundry http://obofoundry.org/

18. 18 for science if we annotate a database or body of literature with one high-quality biomedical ontology, we should be able to add annotations from a second such ontology without conflicts AND WITHOUT THE NEED FOR MAPPINGS orthogonality of ontologies implies additivity of annotations The OBO Foundry http://obofoundry.org/

19. 19 CRITERIA  IDENTIFIERS: The ontology possesses a unique identifier space within OBO.  VERSIONING: The ontology provider has procedures for identifying distinct successive versions to ensure BACKWARDS COMPATIBITY with annotation resources already in common use  The ontology includes TEXTUAL DEFINITIONS and where possible equivalent formal definitions of its terms. CRITERIA

20. 20  CLEARLY BOUNDED: The ontology has a clearly specified and clearly delineated content.  DOCUMENTATION: The ontology is well- documented.  USERS: The ontology has a plurality of independent users. CRITERIA The OBO Foundry http://obofoundry.org/

21. 21  COMMON ARCHITECTURE: The ontology uses relations which are unambiguously defined following the pattern of definitions laid down in the OBO Relation Ontology.* * Smith et al., Genome Biology 2005, 6:R46 CRITERIA The OBO Foundry http://obofoundry.org/
