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.
