Genomic Standards Consortium

The Genomic Standards Consortium (GSC) is an open-membership working body formed in September 2005. The aim of the GSC is making genomic data discoverable. The GSC enables genomic data integration, discovery and comparison through international community-driven standards.

Memorandum of Understanding (MoU) between TDWG and the GSC

The Biodiversity Information Standards (TDWG) group and the Genomic Standards Consortium (GSC) have emerged as de facto (meta)data standards authorities in the biodiversity domain. The former’s scope spans biodiversity data at large, while the latter focuses on genomic, and then multi-omic, data and metadata such as lab protocols or chemical/physical measurements. Their activities, technologies, and management structures have been largely parallel, with some notable exceptions catalysed through joint interest groups such as the Genomic Biodiversity Working Group (GBWG).

The overlap of TDWG and the GSC in multi-omic biodiversity data is an opportunity to begin sustainable convergence of the (meta)data standards these organisations maintain. Most notably among these, are the Darwin Core (DwC) and the Minimal Information about any (x) Sequence (MIxS) specifications. This memorandum builds on the output of a GBWG task group to propose a solution for sustained mapping and scalable interoperation of both DwC and MIxS. Its goal is to ensure that TDWG and the GSC create a lasting and continuous model to synchronise their standards, eventually promoting full bi-lateral integration.


Recognizing that both the Biodiversity Information Standards (TDWG) group and the Genomic Standards Consortium (GSC) have established well-adopted and community-driven (meta)data specifications for sequence-based biodiversity data;

Further recognizing that users of one standard specification should not have to invest additional effort in independently translating their (meta)data into another;

It is resolved that:

Additionally recognizing that unilateral innovation and research actions will propose and implement alternative mappings and extensions to sequence-based metadata specifications.

It is further resolved that:
