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.

GSC Minimum Information about any Sequence (MIxS)

The GSC family of minimum information standards (checklists) are collectively referred to as MIxS (Minimum Information about any (x) Sequence).

We have defined a set of core descriptors for genomes, metagenomes and the samples thereof. The intention is to enable the capture of an extended level of metadata to that already captured by the INSDC archives.

In addition to the sequence related metadata that forms the core of the checklists, we also provide environmental package “extensions” of recomended terms that aim to standardize sets of measurements and observations describing particular sampling events and habitats. These extensions are applicable across any and all of MIxS checklists.


As of release 5.0, the following checklists are under the MIxS umbrella:

MIGS and MIMARKS are further divided into additional subchecklists, based on the genome sequence in question, or the sequencing type.

Core and type-specific descriptors

All checklists share the same central set of core (Minimum) descriptors, which are:

Each checklist is then defined by additional type-specific descriptors. These specific descriptors are summarized below for each checklist and subchecklist. Please note that this summary only includes minimum information for each sequence type, meaning that other conditional and optional descriptors are not included here.













In order to encourage more comprehensive metadata inclusion with sequence data the GSC have facilitated the development of many extensions that can be used in addition to the Minimum Information for each checklist. These extensions consist of many recomended terms that have been compiled by experts in the relevant field of research. Explore all the ready made checklist extensions that we have available. If there is not a suitable checklist already available and you are interested in developing your own extention, this page also contains details on Developing Extensions that you may find useful.

The checklists

The current versions of the checklists are available in our GitHub repository here. The github repository is also where future versions are developed and discussed, please feel free to join the discussion using the github issue tracker. In addition there are more techincal speficication available in the GitHub Wiki

You can find all previous versions of the checklists in our mixs-legacy GitHub repository.

The Terms

The complete set of terms defined across all of the checklists and packages can be found here. If you are interested in a specific term or terms, we provide a simple search function to aid you in finding the relevant term(s).
