Identification information (includes data and service identification). The following is adapted from OpenGIS® Metadata (Topic 11) specification.
Identification information contains information to uniquely identify the data. Identification information includes information about the citation for the resource, an abstract, the purpose, credit, the status and points of contact. The identification entity is mandatory. It may be specified (subclassed) as data identification when used to identify data and as service identification when used to identify a service.
Identification is an aggregate of the following entities:
Format, format of the data
BrowseGraphic, graphic overview of the data
Usage, specific uses of the data
Constraints, constraints placed on the resource
Keywords, keywords describing the resource
MaintenanceInformation, how often the data is scheduled to be updated and the scope of the update
The geographic box and geographic description elements of data identification are conditional; one of them shall be included if the dataset is spatially referenced. If necessary both may be used.
