Technical Architecture Group (TAG) Charter

TDWG Interest Group


Core Members


TDWG consists of a series of Interest Groups and Task Groups that focus on separate but related issues within biodiversity informatics standards. The Executive Committee has an overall responsibility for the direction of the organization but a group is needed that focuses on integration between the subgroups at a technical level. If the Technical Architecture Group (TAG) does not exist, Task Groups may create incompatible or contradictory standards. Opportunities could also be missed for re-use of strategies and standards from other groups. The formation of a TAG within a standards organization is considered best practice - as illustrated by successful organizations such as the Open Geospatial Consortium (OGC), the Internet Engineering Task Force (IETF) and the World Wide Web Consortioum (W3C).

Goals Outputs and Outcomes

  • Maintain an account of the technical aspects of current TDWG standards and activities including how they relate to each other and how they relate to other external standards and technologies.
  • Develop technical standards and guidelines for how TDWG standards should use underlying technologies in a consistent fashion.
  • Maintain an overall architectural vision for how TDWG standards could interoperate with each other and with standards developed elsewhere in the biodiversity informatics community and more widely.
  • Provide technical advice to the Executive Committee on proposed groups and standards.
  • Provide advice to TDWG members on how their work can integrate with others.


  • Produce a yearly review and forecast of technical issues within TDWG prior to the annual meeting - The Roadmap.
  • Provide formal feedback to the Executive Committee on proposed groups and standards as part of TDWG management processes.
  • Be proactive in offering advice to TDWG members who are developing proposals for new groups and standards.
  • Form Task Groups to:
    • Investigate new technologies and make the results available to other TDWG subgroups.
    • Establish infrastructure for a common architecture when this falls outside the remit of a particular interest group.

Becoming Involved

Contributions from all interested parties are welcome. Each subgroup within TDWG is encouraged to have a suitably skilled member active within the TAG. Additionally, it is possible to:

  • Read the latest news on the TAG TDWG Website.
  • See activity and participate on the TAG Wiki.
  • Join the mailing list.
  • Post queries to the mailing list or write to the Convenor.

History and Context

The TAG was formed at the TDWG 2005 meeting in St Petersburg with the remit of developing a common standards development architecture for TDWG.


The TDWG Technical Architecture Group:

  • Develops a common standards development architecture,
  • Maintains technical compatibility between TDWG standards and those produced by other groups.
  • Produces a yearly technical roadmap and
  • Provides both formal and informal advice to the TDWG Executive and membership.
