Subgroup onStructure of Descriptive Data (Gregor Hagedorn Convenor) Bob Morris presenting
XML Schema for the exchange of • Characters, states, descriptions of taxa and specimens, and authored polytomous keys • Goal was to modernize DELTA • Supports “coded” (i.e. database driven) and natural language descriptions (especially for incremental refinement of NLP against legacy literature)
SDD Provides • Categorical and numerical states (including statistical measures) • Multimedia objects associated with descriptions and their parts • Shared (global) states or private (local) states • Part- , taxonomic-, and untyped hierarchies • Modifiers (“usually smooth”, “usually red, occasionally blue”…) can be associated with statistical measures. • Polymorphic characters support higher level taxa
Architecture • No predetermined controlled vocabulary • Constrained XML-Schema Key/Keyref separates controlled vocabularies (“Terminology”) from descriptions. • Descriptions built from keyrefs to Terminology. Constraints prevent stupid assignments like winglength = “red”
Resources and next steps • SDD 1.0 was approved last year • SDD 1.1RC2 out for 3 months, RC3 likely to be last before SDD 1.1 • Primer, Draft for comment shortly available • SDD Wiki at http://wiki.tdwg.org/twiki/bin/view/SDD mainly of historical interest except for RC2 discussion
Current projects • Identify Life (Kevin Thiele)– repository of descriptive terminologies expressed in SDD • Import/export SDD (Mostly SDD1.1 RC2): • Lucid 3 • Norm Johnson hymenoptera db (early SDD) • UMASS-Boston Electronic Field Guide generated EFGs • UMB Import/Export generator (accepts XML schema and mappings, produces Java source code for import/export • UMB visual SDD editor, includes NEXUS import
Current projects • AMNH digitization project has extracted descriptive statements in taxonomic treatments in legacy literature with NLP (Guido Sauter. Karlsruhe) • Fine grained SDD on descriptive statements in legacy literature with NLP (Bryan Heidorn, Illinois, with Donat Agosti, Bob Morris collaborating, maybe aided by a Hymenoptera ontology being developed in OBO by Neil Sakhar (+Agosti, Norm Johnson)
