Uberon: opening up to community contributions
The document discusses Uberon, an integrative multi-species anatomy ontology. It describes Uberon's taxonomic scope covering metazoans with a focus on vertebrates. It outlines how Uberon is edited on GitHub and maintained with cross-references to other species-specific anatomy ontologies. It also discusses how phenotypes from the Phenotype and Human Phenotype Ontology are directly mapped to Uberon and species-specific anatomies, as well as considerations for which anatomy ontology a phenotype ontology should use.

- 11. Taxonomic Scope • Coversmetazoan – (applies to both CL and Uberon) • Focus on vertebrates – Overlap between Uberon and WBbt or PLANA is very small • Brain, circulatory organ, epithelium, … • But we now have an insecta module in Uberon
- 12. Editing Uberon • GitHubrepo layout predates ODK – Some oddities! • All content is in uberon_edit.obo – [caveat: phenoscape and insecta extensions still to be incorporated] – Can be opened and edited in Protégé • Anyone can make Pull Requests – Travis-CI will check the PR • Release cycle is semi-regular
- 13. Maintenance of xrefsin Uberon • Xrefs to multiple other AOs maintained within uberon_edit.obo – All manually curated – Use entity-matching for assistance – E.g. ZFA, FMA, EMAPA, MA, … • Some AOs also maintain reciprocal mappings back ‘up’ to Uberon – E.g. XAO – No official sync pipeline as yet • Is this how people want to maintain this moving forward?
- 14. Translation of xrefsto axioms in Release • Each ssAO xref is treated as a taxon- equivalence axiom – E.g. ZFA:heart EquivalentTo Uberon:heart and part-of some Danio rerio – See ontology metadata for mappings to taxa • Should we change any of these? E.g. species vs genus – These go in inter-ontology bridge files – Reasoner checks performed pre-release
- 15.
- 17. Uberon and DesignPatterns • Uberon pre-dated DOSDPs • Some high-level DPs are specified as narrative documents – E.g. modeling endochondral elements document • DOSDP templates are in progress • Lots of New Term Requests are for things like left + right subclasses of existing classes
- 18. How people havecontributed so far • Issue Tracker • External Ontology Alignment – Other AOs – GO – Phenotype Ontologies • Extension modules – Phenoscape – Insecta • All direct edits by yours truly
- 19. Contribution model movingforward • PRs open to anyone (with basic training) – On uberon_edit.obo – On TSVs (TODO) • Core of editors will merge PRs – Core TBD • Make release pipeline easier to run – Help from ssAOs appreciated (e.g. standardize on relations) – Run more frequently, possibly as Jenkins job
- 20. Which AO shoulda phenotype ontology use? • MP and HP use Uberon (and CL) directly • Non-mammalian use their own – Species-specific phenotypes inferred to be under generic ones • Advantages of Uberon (and CL) – Work has been done up-front to try and ensure consistency with other ssAOs, GO, phenotype ontologies – Reasonably complete is-a, part-of, develops-from • Disadvantages – Generalizing across species may lose information – Low coverage for invertebrates (intentional) • Discussion – Should we have mechanism for ‘pushing down’ suggestions to ssAOs?
