Basic Standards Recommendations

The most widely deployed formats for biodiversity occurrence data are Darwin Core (wiki) and ABCD (wiki).

The TDWG community's priority is the deployment of Life Science Identifiers (LSID), the preferred Globally Unique Identifier technology and transitioning to RDF encoded metadata as defined by a set of simple vocabularies. All new projects should address the need for tagging their data with LSIDs and consider the use or development of appropriate vocabularies.

TDWG's activities within the biodiversity informatics domain can be found in the Activities section of this website.

TDWG 2015 Annual Conference

Biodiversity Information Standards (TDWG) will hold its 2015 annual conference 28 September to 3 October 2015 in Nairobi, Kenya.  This is TDWG’s first conference in Africa!  The theme of the conference is Applications, Standards and Capacity Building for Sustaining Global Biodiversity.  Subprograms will include: Digitization, Semantic Technologies, Phyloinformatics, Outreach and Collaboration, ePublications, Trait Data, and Conservation informatics. A  5-day capacity building workshop for African participants at the conference will be organized, focussing primarily on biodiversity collection digitization, biodiversity databases, data cleaning, and georeferencing. The workshop dates are 21-25 September 2015 (the week before the TDWG conference).

We need IT professionals, taxonomists, ecologists, geoscientists, and librarians. We need members from institutions and agencies that do or could use our standards to make their data more usable. Your participation ensures that what we develop will save you time and money.
