This coverages (temporal, spatial, and taxonomic) represent the extent of applicability of the resource in those domains. Temporal coverage Temporal coverage descriptor. This element specifies temporal coverage, and allows coverages to be a single point in time, multiple points in time, or a range of dates. Dates can be expressed in tems of both calander dates and geologic dating systems. The TemporalCoverage complex type was introduced into EML 1.4. Geographic coverage Geographic coverage information. Geographic Coverage is a container for spatial information about a a project, a resource, or an entity within a resource. It allows a bounding box for the overall coverage (in lat long), and also allows descriptin of arbitrary polygons with exclusions. The geographicCov element is derived from the NBII standard. Taxonomic coverage Taxonomic coverage information. Taxonomic Coverage is a container for Taxonomic information about a a project, a resource, or an entity within a resource. It includes a list of species names (or higher level ranks) from one or more classification systems. The TaxonomicCoverage complex type was introduced in EML 2 and derived from the NBII taxonomy element. Temporal coverage Temporal coverage descriptor. This element specifies temporal coverage by start and stop date. The TemporalCoverage complex type was introduced into EML 1.4.
