CMDI (Component Metadata Infrastructure)

The Component Metadata Infrastructure provides a framework to create and use self-defined metadata formats. It relies on a modular model of so-called metadata components, which can be assembled together, to improve reuse, interoperability and cooperation among metadata modelers. The model is standardised in ISO 24622-1 and ISO 24622-2. The serialization is typically in XML. Metadata in this format are often distributed via OAI-PMH. The definition of data categories is provided externally, for example by linking to schema.org or the Clarin Concept Registry.

MIBBI (Minimum Information for Biological and Biomedical Investigations)

The MIBBI Project was an international collaboration seeking to harmonize the efforts of the various bioscience communities developing Minimum Information (MI) reporting guidelines or checklists. Approximately 40 such checklists registered with the project.

The MIBBI Foundry was an attempt to identify common features of the various MI checklists and codify them into modules. The aim was to evolve the existing checklists towards formal intercompatibility, and to enable new checklists to be produced by selecting and extending the available modules.

The concept was realized initially through the joint efforts of the Proteomics Standards Initiative, the Genomic Standards Consortium and the MGED RSBI Working Groups.

While the MIBBI Foundry did not develop to the point where it could become a true, technical parent standard for the MI checklists, the MIBBI Project provided a useful grouping of standards that shared a common purpose, philosophy and inspiration.

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.
