  1. TDWG Biodiversity Information Standards http://www.tdwg.org Renato De Giovanni Member, TDWG Executive Committee renato@cria.org.br December 1st, 2008

  2. TDWG - Biodiversity Information Standards Previously: Taxonomic Databases Working Group • International not-for-profit organization that develops standards and protocols for sharingbiodiversity data. • All outcomes are freely available to the public. • Anyone can participate in subgroup discussions – no need to be a TDWG member, although membership is always encouraged.

  3. TDWG Mission • Develop, adopt and promote standards and guidelines for the recording and exchange of data about organisms. • Promote the use of standards through the most appropriate and effective means. • Act as a forum for discussion through holding meetings and through publications.

  4. History • TDWG activities date from 1985, when a group of botanists met at the Conservatoire et JardinBotaniques in Geneva. • The aim was to explore ideas on standardization and collaboration between projects and institutions that were working with plant taxonomic databases. • This was before the Internet became widespread! • First meeting was probably very successful…

  6. Participation in the last meetings

  7. TDWG Annual Meeting • Opportunity for TDWG to assess achievements, plan the next activities, elect new officers, and to conduct any other relevant business. • Opportunity for the subgroups to make progress by organizing specific face-to-face meetings. • Opportunity for all participants to attend a biodiversity informatics conference, present their work, interact with other people, become current with new technologies, and learn about other projects across the globe.

  8. TDWG Expansion • In 1988 TDWG became affiliated to the International Union of Biological Sciences (IUBS): Zoologists and microbiologists started to participate. • In the 1990s the Internet started to flourish: dream of being able to aggregate knowledge on the world’s biodiversity and bring it to every biologist’s desktop. • In 2006 TDWG got a US$1.5 million grant from the Moore Foundation: Major restructuring process. • Currently, TDWG members are a mix of biologists, ecologists, computer scientists, taxonomists, librarians, geoscientists...

  9. TDWG Types of Standards • Technical Specification • Protocol, service, procedure, format • Applicability Statement • How an existing technology can be applied (e.g. LSIDs) • Best Current Practice • Description of good behavior • Data Standard • Content specification or controlled vocabulary

  10. TDWG Standards • Users Guide to the DELTA System (1986) • Floristic Regions of the World (1986) • International Transfer Format for Botanic Garden Plant Records (1987) • Index Herbariorum. Part I: The Herbaria of the World (1990) • Botanico-periodicum-huntianum/supplementum (1991) • XDF – Language for Definition and Exchange of Biological Datasets (1991) • World Geographical Scheme for Recording Plant Distributions (1992) • Authors of Plant Names (1992) • Plant Names in Botanical Databases (1995) • Plant Occurrence and Status Scheme (1995) • Economic Botany Data Collection Standard (1995) • HISPID3 - Herbarium Information Standards and Protocols for Interchange of Data (1996) • Access to Biological Collection Data (ABCD) (2005) • Structure of Descriptive Data (2005) • Taxonomic Concept Transfer Schema (2005) • Standards Documentation Specification (draft) • Life Sciences Identifiers (LSID) Applicability Statement (draft) • Natural Collections Descriptions (draft) • TDWG Access Protocol for Information Retrieval —TAPIR (in preparation) • DarwinCore (in preparation) Retired/ Deprecated Standards -no champion Current Standards Draft Standards

  11. TDWG Infrastructure Project - Aims • Devise a new long-term support model for the organization. • Develop appropriate procedural rules. • Set up a new infrastructure to support all its activities. • Make the organization and its scope known to the public. • Effectively disseminate its work products.

  12. TDWG Infrastructure Project - Results • A new constitution and standards development process are now in place to ensure the quality of standards. • All working groups have been reorganized and received support to accomplish their tasks. • A new integrated web environment is now available (content management system, Wiki, mailing lists, journal management and publishing system, and version control system). • A new group has been created to define a common technical architecture for all TDWG standards.

  13. Current Working Structure • TDWG is governed by an Executive Committee consisting of: • Chair • Secretary • Treasurer • Editor (journal and website) • 6 Regional Secretaries (based on the regions of the world) • 2 Additional individuals may be appointed by the officers • Officers are elected by the membership during the annual meeting. • When voting is required, results are based on simple majority. One vote for each member.

  14. Standards Development Process • Interest Groups provide a base for discussing goals and strategies for data sharing in a particular area. • Task Groups are created within Interest Groups to develop a specific product in a specific timeframe. • Any TDWG member can petition for the establishment of a new Interest Group by submitting a charter to the Executive Committee. • Both kinds of Groups are managed by Conveners responsible for developing consensus, preparing the standards specification and reporting back to the Executive Committee annually.

  15. Standards Development Process

  16. New Standards License • To be defined by the TDWG Standards Documentation Specification (under final review). • New standards will normally be released under the Creative Commons “By Attribution” license, which means that users will be free: • To Share: to copy, distribute, and transmit the work; • To Remix: to make derivative works; • Under the condition that users must attribute the work to TDWG by citing the standard by name and providing the URL to the original document, but not in any way suggesting that TDWG endorses the user or the use of the work.

  17. TDWG Interest Groups • Biological Descriptions • Species Profiles (being established) • Geospatial • Imaging & Multimedia • Invasive Species • Literature • Natural Collections Descriptions • Observation and Specimen Records • Taxonomic Names and Concepts • Technical Architecture • Global Identifiers • Access Protocol for Information Retrieval • Phylogenetics (being established)

  18. New TDWG Standards Architecture • Principle 1: TDWG standards apply to shared data • Enables interoperability of providers and consumers with radically different internal implementations. • Does not dictate internal structures on data providers or consumers. • ‘Format’ matters when data crosses boundaries.

  19. Data Sharing Scenario Typical scenario for complex biodiversity research will require different kinds of data from multiple sources to be combined: Nomenclature Geospatial Taxonomy Molecular ? Description Interaction Occurrence Literature

  20. TDWG Architecture Requirements • Data providers will not know who will use their data or how it will be combined with data from other sources. • Data consumers will need some level of commonality across all data received so that it can be combined for analysis without much pain – even for new types of combinations. • Providers and consumers need to be able to reference pieces of data in a consistent and reliable way. • Data exchange needs to be facilitated by adopting common rules.

  21. New TDWG Standards Architecture • Principle 2: Biodiversity data will be modelled as graph of identifiable objects. • Objects will be defined by an ontology: Understandable by humans and computers. • Globally unique identifiers will be used to link objects across the network. • A common exchange protocol will be available to search and retrieve data.

  22. TDWG Architecture Components • Ontology • Globally Unique Identifiers • Exchange Protocols

  23. TDWG Ontology • Initial prototype available as a series of UML diagrams and OWL/RDF vocabularies.

  24. Global Identifiers • The Global Identifier Task Group produced an Applicability Statement for Life Science Identifiers (LSIDs) which is under final review. • GUID systems like LSID provide mechanisms to identify and access data objects on the Web. • Identifiers must be persistent (permanently associated with a data object). • Identifiers must be global in scope. • Identifiers must allow clients to access the underlying data object in a standard way.

  25. Data Exchange Protocol • The TDWG Access Protocol for Information Retrieval (TAPIR) Task Group is finalizing the specification. TAPIR : • Is based on established Web standards like HTTP, XML and XML Schema. • Is independent of the data being exchanged (can be used to access a wide range of data). • Can return data in different formats. • Has five operations to address basic needs of federated networks: access to metadata and capabilities of the service, preliminary data discovery and data mining, searching, and service monitoring.

  26. TDWG Priorities for 2009 • Promote standards through the TDWG process (Standards Documentation Specification, LSID Applicability Statement, DarwinCore and TAPIR) . • Foster the uptake of LSIDs using RDF vocabularies. • Complete the core ontology and vocabularies. • Develop a strategy on metadata. • Reach out to the community for support and to ensure TDWG standards address community needs.

  27. Membership • We need more people and institutions to support the development of more effective standards. • Current membership is small considering the size of the community and the international significance of the work. • Individual membership: • US$75 / year • Institutional membership: • US$500 / year • (US$400 before March 30)

  28. TDWG Challenges • Developing effective standards is not easy • Involves people with different interests and perspectives – also need to deal with conservatism, rivalries, egos... • Involves complex areas of knowledge – trivial issues are not trivial... • Involves multiple disciplines – experts from different areas need to understand each other • Information Technology evolves very quickly – standards can soon become obsolete! • TDWG needs more resources to facilitate rapid development of effective standards

  29. TDWG Challenges • Some think that any competent individual could probably develop a standard faster than a group... • Group outcomes can be odd – an amalgam of different views: “A camel is a horse designed by a committee” (unknown source) • “If you want to go fast around a well-prepared track, get yourself a racehorse. • If you want to reliably reach a distant destination across unknown terrain, you are probably better off on a camel.” (M. Champion)
