ISA-Tab

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.

Minimum Information about any (x) Sequence (MIxS)

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.

PDBx/mmCIF (Protein Data Bank Exchange Dictionary and the Macromolecular Crystallographic Information Framework)

Protein Data Bank archive (PDB) is the single worldwide archival repository of information about the 3D structures of proteins, nucleic acids, and complex assemblies, managed by the Worldwide PDB (wwPDB). The PDB Exchange Dictionary (PDBx) is used by the wwPDB to define data content for deposition, annotation and archiving of PDB entries. PDBx incorporates the community standard metadata representation, the Macromolecular Crystallographic Information Framework (mmCIF), orginally developed under the auspices of the International Union of Crystallography (IUCr). PDBx has been extended by the wwPDB to include descriptions of other experimental methods that produce 3D macromolecular structure models such as Nuclear Magnetic Resonance Spectroscopy, 3D Electron Microscopy and Tomography.

REMBI (Recommended Metadata for Biological Images)

Recommended Metadata for Biological Images (REMBI) provides guidelines for metadata for biological images to enable the FAIR sharing of scientific data. REMBI is the result of the bioimaging community coming together to develop metadata standards that describe the imaging data itself, together with supporting metadata such as those describing the biological study and sample.

Repository-Developed Metadata Schemas

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