“I’m here to fight for truth, justice, and the American way.”– SupermanOntologies, vocabularies, and standards help provide acommon understanding of the structure of information,allowing us to break data down to its fundamental parts.
“Your identity is your most valuable possession. Protect it.And if anything goes wrong, use your powers.” - ElastigirlIdentifiers allow us to tag, track, or reference any object orprocess. They must be awesome: persistent, unique, resolvable.

A Data Integration Experiment:Link records between VertNet and Genbank using the Darwin CoreTriplet (InstitutionCode : CollectionCode : CatalogNumber)• 1,400,000 VertNet Records• 460,739 Genbank records (filtered by VertNet institutions)Question:What % of harvested Genbank records could be linked to VertNetvoucher specimen records using the Darwin Core Triplet?Back to Reality …Less than 1%!
NONE of the identifiers (that we found) employ strategies to ensuretruly long-term persistence, decoupling metadata from the identifieritself.Identifier ChallengesDarwin Core triplets (at least as currently specified in standards, andimplemented) do not do well for linking data.Interim SolutionsFix DwC Triplets standards/validation (that’s you Genbank), build aTriplet resolverPURLAwesome Solutions

Ontology / Vocabulary ChallengesNeed to clarify assumptions behind concepts• Individual / Material Sample / Specimen / Population• Different interpretations x-domains: MIxS, INSDC, DwC, OBISolutions:• Continually improve clarity in definitions• Work towards more robust standards governance frameworks• Implement test beds and better understand use casesVarying degrees of formalism• Checklists, spreadsheets, RDF, OBO, OWLInsufficient support for standards organizations• Consisting of tenuous structures maintained by informal networks ofactive volunteers
