A semantic standard developed by the Food and Agriculture Organization (FAO) of the United Nations, AgMES enables description, resource discovery, interoperability and data exchange of different types of information resources in all areas relevant to food production, nutrition and rural development.
The standard is maintained by AIMS (Agricultural Information Management Standards), and while it has been used in various application profiles, it is now deprecated for new uses and will no longer be updated.
The AVM scheme supports the cross-searching of collections of print-ready and screen-ready astronomical imagery rendered from telescopic observations (also known as ‘pretty pictures’). The scheme is compatible with the Adobe XMP specification, so the metadata can be embedded within common image formats such as JPEG, TIFF and PNG.
Such images can combine data acquired at different wavebands and from different observatories. While the primary intent is to cover data-derived astronomical images, there are broader uses as well. Specifically, the most general subset of this schema is also appropriate for describing artwork and illustrations of astronomical subject matter.
AVM is a proposed recommendation of the International Virtual Observatory Alliance and was last updated in 2011.
The CF standard was originally framed as a standard for data written in netCDF format, with model-generated climate forecast data particularly in mind. However, it is equally applicable to observational datasets, and can be used to describe other formats. It is a standard for “use metadata” that aims both to distinguish quantities (such as physical description, units, and prior processing) and to locate the data in space–time.
Sponsored by the NetCDF Climate and Forecast Metadata Convention, the current version dates from December 2011.
A well-established standard file structure for the archiving and distribution of crystallographic information, CIF is in regular use for reporting crystal structure determinations to Acta Crystallographica and other journals.
Sponsored by the International Union of Crystallography, the current standard dates from 1997. As of July 2011, a new version of the CIF standard is under consideration.
The Common Information Model (CIM) describes climate data, the models and software from which they derive, the geographic grids used to calculate and project them, and the experimental processes (typically simulations) that produced them.
The CIM was originally developed by the EU-funded Metafor Project. It is now maintained and developed by Earth Science Documentation (ES-DOC). The latest release dates from 2012.

FITS is an image data file format for encoding astronomical data. The WCS (World Coordinate System) conventions map elements in data arrays to standard physical coordinates in the sky. FITS has provisions for image metadata encoded in an ASCII header at the beginning of files.
The technical specifications defined by the IVOA (International Virtual Observatory Alliance) enable interoperability between and the integration of astronomical archives across the world into an international virtual observatory. They include several data models that act as metadata schemas for particular data types: for example, photometry data, simulation data, space-time coordinates, spectral lines data, spectral data, observational data, and the physical parameter space of astronomical datasets.
These data models are under active development by the IVOA Data Modelling Working Group.
Additional recommendations have been made for metadata concepts and terms necessary for the discovery and the use of astronomical data collections and services.
An internationally-adopted schema for describing geographic information and services. It provides information about the identification, the extent, the quality, the spatial and temporal schema, spatial reference, and distribution of digital geographic data.
Sponsored by the International Standards Organisation, the first edition of ISO 19115 was published in 2003. It has since been split into parts: ISO 19115-1:2014 contains the fundamentals of the standard; ISO 19115-2:2009 contains extensions for imagery and gridded data; and ISO/TS 19115-3:2016 provides an XML schema implementation for the fundamental concepts compatible with ISO/TS 19138:2007 (Geographic Metadata XML, or GMD).
NeXus is an international standard for the storage and exchange of neutron, x-ray, and muon experiment data. The structure of NeXus files is extremely flexible, allowing the storage of both simple data sets, such as a single data array and its axes, and highly complex data and their associated metadata, such as measurements on a multi-component instrument or numerical simulations. NeXus is built on top of the container format HDF5, and adds domain-specific rules for organizing data within HDF5 files in addition to a dictionary of well-defined domain-specific field names.
This encoding is an essential dependency for the OGC Sensor Observation Service (SOS) Interface Standard. More specifically, this standard defines XML schemas for observations, and for features involved in sampling when making observations. These provide document models for the exchange of information describing observation acts and their results, both within and between different scientific and technical communities.
OpenPMD provides naming and attribute conventions that allow the exchange of particle and mesh based data from scientific simulations and experiments. The primary goal is to define a minimal set/kernel of meta information that enables the sharing and exchange of data to achieve
OpenPMD suits any kind of hierarchical, self-describing data format, such as, but not limited to ADIOS1 (BP3), ADIOS2 (BP4), HDF5, JSON, and XML.
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.
Some repositories have decided that current standards do not fit their metadata needs, and so have created their own requirements.
The Standard for Documentation of Astronomical Catalogues is a set of conventions for archiving astronomical data. As well as path, filename and data format conventions, it also specifies how to construct a plain text description file for documenting the data files. It was developed as an alternative to FITS that would be more suited to archives, permit human inspection, and allow manipulation via standard Unix command-line tools.
