Module Documentation: eml-entity
Back to EML Contents
The EML Entity Module defines the logical characteristics of every entity in the dataset. Entities are usually tables of data with a fixed logical structure, but could also be other types of data such as raster or vector image data. The "table-entity" element is used to describe all table entities, and the "other-entity" element would be used to describe all other types of entities. Specific details of non-tabular entities are left to other standards (e.g., for remote sensing data, one should include a spatial metadata module such as the FGDC Content Standard for Digitial Geospatial Metadata [CSDGM]).

Unique identifier
Summary:
The unique identifier of this metadata file or object.

This element gives the name of the catalog system in which this identifier is used. It is useful to determine the scope of the identifier, and to determine the semantics of the various subparts of the identifier. Unresolved issue: can or should this be a URI/URL pointing to the catalog system, or just the name?
Example:
<identifier system="metacat">nceas.3.2</identifier>
Lineage:
New to EML 2.0.
