A widely used, international standard for describing data from the social, behavioral, and economic sciences. Two versions of the standard are currently maintained in parallel:
Both versions are XML-based and defined using XML Schemas. They were developed and are maintained by the DDI Alliance.
A British cultural heritage standard for recording information on buildings, archaeological sites, shipwrecks, parks and gardens, battlefields, areas of interest and artefacts.
Sponsored by the Forum on Information Standards in Heritage, MIDAS Version 1.1 was released in October 2012.
The goal of these standards is to expose the rich content in aggregations of Web resources to applications that support authoring, deposit, exchange, visualization, reuse, and preservation. The standards support the changing nature of scholarship and scholarly communication, and the need for cyberinfrastructure to support that scholarship, with the intent to develop standards that generalize across all web-based information including the increasing popular social networks of “Web 2.0”.
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.
A study-data oriented model, primarily in support of the ICAT data managment infrastructure software. The CSMD is designed to support data collected within a large-scale facility’s scientific workflow; however the model is also designed to be generic across scientific disciplines.
Sponsored by the Science and Technologies Facilities Council, there is reference to CSMD 3.0 development in 2010; however, the latest full specification available is v 2.0, from 2004.
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.
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.
Sponsored by Biodiversity Information Standards TDWG - the Taxonomic Databases Working Group, the current specification was last modified in 2007.
A body of standards, including a glossary of terms (in other contexts these might be called properties, elements, fields, columns, attributes, or concepts) intended to facilitate the sharing of information about biological diversity by providing reference definitions, examples, and commentaries.
Sponsored by Biodiversity Information Standards (TWDG), the current standard was last modified in October 2009.
Ecological Metadata Language (EML) is a metadata specification particularly developed for the ecology discipline. It is based on prior work done by the Ecological Society of America and associated efforts (Michener et al., 1997, Ecological Applications).
Sponsored by ecoinformatics.org, EML Version 2.1.1 was released in 2011.
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.

Observ-OM is founded on four basic concepts to represent any kind of observation: Targets, Features, Protocols (and their Applications), and Values. It is intended to lower the barrier for future data sharing and facilitate integrated search across panels and species. All models, formats, documentation, and software are available for free and open source (LGPLv3) at http://www.observ-om.org.
OME-XML is a vendor-neutral file format for biological image data, with an emphasis on metadata supporting light microscopy. It can be used as a data file format in its own right, or as a way of encoding metadata within a TIFF or BigTIFF file (for which purpose there is the OME-TIFF specification).
The standard is maintained by the Open Microscopy Environment Consortium, and was last updated in June 2012.
Some repositories have decided that current standards do not fit their metadata needs, and so have created their own requirements.
A metadata standard for describing environmental monitoring activities, programmes, networks and facilities published by the UK Environmental Observation Framework (UKEOF).
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.
Sponsored by the UN AIMS - Agricultural Information Managment Standards, the current standard was issued in November 2010.
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.

An early metadata initiative from the Earth sciences community, intended for the description of scientific data sets. It inlcudes elements focusing on instruments that capture data, temporal and spatial characteristics of the data, and projects with which the dataset is associated. It is defined as a W3C XML Schema.
Sponsored by the Global Change Master Directory, the DIF Writer's Guide Version 6 is from November 2010.
A widely-used, but no longer current standard defining the information content for a set of digital geospatial data required by the US Federal Government.
CSDGM was sponsored by the US Federal Geographic Data Committee. However, in September 2010 the FGDC endorsed ISO 19115 and began encouraging federal agencies to transition to ISO metadata.
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:
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.

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.
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.
SDAC was developed by CDS (Centre de Données astronomiques de Strasbourg). Version 2.0 is the most recent; it was released in February 2000.
An information model for describing the elements of the heliophysics data environment, and a set of resource types which can be used to describe data along with its scientific context, source, provenance, content and location. It is designed to support a federated data system where data may reside at different locations and may be seperated from the metadata which describes it. The preferred expression form is XML.
The Space Physics Archive Search and Extract (SPASE) effort is implemented by the SPASE Consortium which is composed of representatives of the international Heliophysics data community. The Current Release of the data model (2.2.2) was updated in October 2012.

A set of common technical and statistical standards and guidelines to be used for the efficient exchange and sharing of statistical data and metadata.
Sponsoring institutions include BIS, ECB, EUROSTAT, IMF, OECD, UN, and the World Bank. Technical Specification 2.1 was amended in May 2012.
The Common European Research Information Format is the standard that the EU recommends to its member states for recording information about research activity. Since version 1.6 it has included specific support for recording metadata for datasets.
A set of mandatory metadata that must be registered with the DataCite Metadata Store when minting a DOI persistent identifier for a dataset. The domain-agnostic properties were chosen for their ability to aid in accurate and consistent identification of data for citation and retrieval purposes.
Sponsored by the DataCite consortium, version 3.0 was recently released in 2013.
By using DCAT to describe datasets in data catalogs, publishers increase discoverability and enable applications easily to consume metadata from multiple catalogs. It further enables decentralized publishing of catalogs and facilitates federated dataset search across sites. Aggregated DCAT metadata can serve as a manifest file to facilitate digital preservation.
A basic, domain-agnostic standard which can be easily understood and implemented, and as such is one of the best known and most widely used metadata standards.
Sponsored by the Dublin Core Metadata Initiative, Dublin Core was published as ISO Standard 15836 in February 2009.

The PREMIS (Preservation Metadata: Implementation Strategies) Data Dictionary defines a set of metadata that most repositories of digital objects would need to record and use in order to preserve those objects over the long term. It has its roots in the Open Archival Information System Reference Model but has been strongly influenced by the practical experience of such repositories. While the Data Dictionary can be used with other standards to influence the creation of local application profiles, an XML Schema is provided to allow the metadata to be serialized independently.
PREMIS was initially developed by the Preservation Metadata: Implementation Strategies Working Group, convened by OCLC and RLG, and is currently maintained by the PREMIS Maintenance Activity, lead by the Library of Congress.
Provenance is information about entities, activities, and people involved in producing a piece of data or thing, which can be used to form assessments about its quality, reliability or trustworthiness. The PROV Family of Documents defines a model, corresponding serializations and other supporting definitions to enable the inter-operable interchange of provenance information in heterogeneous environments such as the Web.
The standard provides a means to publish multi-dimensional data, such as statistics, on the web in such a way that it can be linked to related data sets and concepts using the W3C RDF (Resource Description Framework) standard. The model underpinning the Data Cube vocabulary is compatible with the cube model that underlies SDMX (Statistical Data and Metadata eXchange), an ISO standard for exchanging and sharing statistical data and metadata among organizations.
Some repositories have decided that current standards do not fit their metadata needs, and so have created their own requirements.
