The most widely deployed formats for biodiversity occurrence data are Darwin Core (wiki) and ABCD (wiki). New deployments of these and other XML based formats should use the TAPIR exchange protocol.

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.

Please consider becoming a member. TDWG needs everyone with a strong interest in biodiversity information to participate in developing effective standards for sharing that information. 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.
