5 TDWG Data Standards Darwin Core Simple XML data model to represent taxon occurrence records (only core attributes) Extensions to handle e.g. curation details, microbial data, image data ABCD Schema – Access to Biological Collection Data More complex XML data model to represent collection or observation data Detailed document structure including features for different communities DiGIR – Distributed Generic Information Retrieval XML protocol for searching remote data resources Suitable for use with a wide range of different data models BioCASe Protocol XML protocol for searching remote data resources with more complex schema (e.g. ABCD) Derived from DiGIR – new unified DiGIR/BioCASe protocol being developed Taxon Concept Schema XML data model currently under development for exchange of nomenclatural/taxonomic data First version to be used for implementation in 2005 SDD Schema – Structured Descriptive Data XML data model for descriptive data relating to taxa or specimens (highly generalised) Suitable for representation of character tables, diagnostic keys, etc.

8 BioCASe-ABCD compared to DiGIR-Darwin Core BioCASe-ABCD model Document-based (response document includes metadata and records as a structured package) Strengths No problem with modelling complex nested structures and repeating elements Fits perfectly with UBIF proposal – ABCD DataSet elements and ABCD Metadata could readily be standardised with the DataSet/Metadata structures from other TDWG standards such as Structured Descriptive Data (SDD) and Taxon Concept Schema (TCS) – with rather little work. DataSets from all three of these could be combined to form a single document with cross-references between sections. Possible weaknesses Not simple for specialist networks to extend the structure with additional elements of their own (requires well-planned open extension points to be designed into the schema), especially if a provider wishes simultaneously to be part of more than one such specialist network. (At present) all elements in the ABCD schema are versioned together. Handling an updated version of the schema requires significant additional effort on the part of providers and users. For example, adding new elements to support plant genetic resource data – without changing the elements for museum/herbarium specimens – requires all users to handle a new version of the schema. DiGIR-Darwin Core model Record-based (response returns a set of records which may contain descriptor elements from any schema) Strengths Massively flexible and extensible model allowing different networks to use a common protocol and shared core elements alongside their own network- specific extensions. (In integrated protocol version) could return ABCD elements as part of response records. If ABCD is treated as a library of elements, this fits even better. Model maps well to supporting a flexible object-oriented data model for biodiversity informatics. Possible weaknesses (In existing version) cannot readily handle complex data structures with nested repeating elements. Records have no intrinsic data type – currently relies on an implicit understanding between user and data provider.

A customs official discovers specimens of a possible pest species of weevil (Curculionidae) on a consignment of agricultural produce at a port of entry. The GBIF Network generates an identification key to support identification of pest weevil species to allow the official to determine appropriate response. This application requires access to data from a wide range of sources, including those GBIF participants that are organisations.

21 Future activity Globally unique identifiers TDWG-GBIF collaboration to develop models to allow data providers to attach persistent identifiers to their data records Allow software to detect multiple instances of the same record Allow users to save resolvable references to specimens, collections, taxon concepts, etc. Schema repository Central library of information on data models Resource for discovering documentation or mappings between different schemas Better support for intelligent software applications Data validation tools Framework for running sets of validation tests against XML data (content values, controlled vocabularies, relating georeference data to named localities, etc.) Support different uses (data providers to locate possible problems in data; users to assure themselves of suitability of data; GBIF to provide metadata on data completeness/coherence) Access to a wide range of taxonomic name data Taxonomic/nomenclatural authorities (nomenclators, global species databases, revisions, etc.) Lists used by different communities/organisations (red lists, pest species, regional checklists, etc.) Customised portals Organised according to taxon lists used by each user Notifications of new data based on user profiles (taxonomic, geographic, etc.)
