The Access to Biological Collections Data (ABCD) Schema is an evolving comprehensive standard for the access to and exchange of data about specimens and observations (a.k.a. primary biodiversity data). The ABCD Schema attempts to be comprehensive and highly structured, supporting data from a wide variety of databases. It is compatible with several existing data standards. Parallel structures exist so that either (or both) atomised data and free-text can be accommodated.

The ABCD Schema was ratified as a standard by the Biodiversity Information Standards Taxonomic Databases Working Group (TDWG) in 2005. It was developed as a community-driven effort, with contributions from CODATA, BioCASE and GBIF among other organizations.

Genome metadata on PATRIC consists of 61 different metadata fields, called attributes, which are organized into the following seven broad categories: Organism Info, Isolate Info, Host Info, Sequence Info, Phenotype Info, Project Info, and Others.

The Investigation/Study/Assay (ISA) tab-delimited (TAB) format is a general purpose framework with which to collect and communicate complex metadata (i.e. sample characteristics, technologies used, type of measurements made) from 'omics-based' experiments employing a combination of technologies.

Created by core developers from the University of Oxford, ISA-TAB v1.0 was released in November 2008.

A common portal to a group of nearly 40 checklists of Minimum Information for various biological disciplines. The MIBBI Foundry is developing a cross-analysis of these guidelines to create an intercompatible, extensible community of standards.

The concept was realized initially through the joint efforts of the Proteomics Standards Initiative, the Genomic Standards Consortium and the MGED RSBI Working Groups. The latest project to register with MIBBI is the MIABie guidelines for reporting biofilm research, as of January 2012.

A list of nearly 40 Minimum Information standards projects registered with the MIBBI initiative.

MIxS currently consists of three separate checklists; MIGS for genomes, MIMS for metagenomes, and MIMARKS for marker genes. To create a single entry point to all minimum information checklists from the GSC and to the environmental packages, we created an overarching framework, the MIxS standard (publication in Nature Biotechnology). MIxS includes the technology-specific checklists from the previous MIGS and MIMS standards, provides a way of introducing additional checklists such as MIMARKS, and also allows annotation of sample data using environmental packages.

Some repositories have decided that current standards do not fit their metadata needs, and so have created their own requirements.
