A universal resource name for the global unique identifier for the specimen or observation record. The identifier should be the complete Uniform Resource Name (URN) for the record. In the absence of a persistent global unique identifier, construct one in the form "URN:catalog:[InstitutionCode]:[CollectionCode]:[CatalogNumber]".

The identifier must uniquely identify a sampling event within each project, and can be any combinations of characters. A sampling event is defined as an attempt to observe birds during a specified amount of time (between TimeObservationsStarted and TimeObservationsEnded) at a location (identified by SurveyAreaIdentifier). Note that data for which the concept of a SamplingEvent refers to different types of SurveyAreas should not be mixed within a single BMDE resource.

Describes the structure of the SamplingEventIdentifier in a way that expresses the relationship between the sampling hierarchical levels (eg, for a stratified survey design, such as plots within quadrats within area or stops within routes). Ideally, the SamplingEventIdentifier should be composed in such a way to allows to identify these various sampling levels, and separating those by a dash. (eg, Route-Stop-UniqueID, or Site-Year-Month-Day).

A unique identifier for a route, transect, set of nets, or any higher organizational unit that is comprised of 1 or more SurveyAreas, traps, or nets.
