Metadata Standards

AgMES - Agricultural Metadata Element Set

A semantic standard for description, resource discovery, interoperability and data exchange for different types of agricultural information resources.

AVM - Astronomy Visualization Metadata

A standard defining discovery metadata for fully rendered astronomical imagery.

CF (Climate and Forecast) Metadata Conventions

A standard for climate and forecast “use metadata” that aims both to distinguish quantities (such as physical description, units, or prior processing) and to locate the data in space–time.

DIF - Directory Interchange Format

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.

FGDC/CSDGM - Federal Geographic Data Committee Content Standard for Digital Geospatial Metadata

BGDC policy states that non-Federally authored standards that are endorsed by the FGDC have the same status as FGDC developed standards. Since ISO 19115 and the associated standards are endorsed by the FGDC, federal agencies are encouraged to transition to ISO metadata as their agencies are able to do so.

ISO 19115

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.

Metafor CIM - Common Information Model

A model for describing numerical experiments carried out by the Earth system modelling community, the models they use, and the data they produce.

Observations and Measurements

This standard specifies an XML implementation for the OGC and ISO Observations and Measurements (O&M) conceptual model, including a schema for Sampling Features.

Repository-Developed Metadata Schemas

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