Field Name Description
GlobalUniqueIdentifier 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]".
DateLastModified The last time when any of the data for the record were modified. Returns values as ISO 861 date and time in UTC(GMT). (see http://www.w3.org/TR/NOTE-datetime). Data sources should use a native datetime data type, if possible.
BasisOfRecord A descriptive term indicating whether the record represents an object or observation
InstitutionID An identifier for the institution having custody of the object(s) or information referred to in the record.
InstitutionCode The code (or acronym) identifying the institution administering the collection in which the organism record is cataloged. No global registry exists for institutional codes; use the code that is "standard" in your discipline.
CollectionCode The code (or acronym) identifying the collection within the institution in which the organism record is cataloged (not applicable to AKNS).
CatalogNumber The alphanumeric value identifying an individual organism record within the collection.

The identifier must uniquely identify a site within each project and may often be contained within a Route and/or a Locality.
SurveyAreaSize Size (ha) of the survey area.
SurveyAreaPercentageCovered Percentage of the SurveyAreaSize actually covered during the sampling event. A missing value is assumed to represent 100%. The value can be smaller for example in cases where the presence of a shoreline reduces the effective size of the normal sampling plot.
SurveyAreaShape Shape of the survey area covered by the observation event.

In the case of a rectangle, this is equal to the size of the shortest side. In the case of a square or a circle, the short axis is equal to the long axis. In the case of a half circle, this is equal to the radius.
SurveyAreaLongAxisOrientation Orientation (decimal degrees, relative to true north) of the long axis of the survey area.
CoordinatesScope Geographic scope of the coordinates, indicating whether they represent the location of the individual sampling event, the route, or another broader geographic area.
SamplingEventIdentifier A unique identifier identifying the sampling event during which or more observations were made. 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.
SamplingEventStructure 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).
RouteIdentifier 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.
TimeObservationsStarted The time of day the entire observation event started (this may be different from the time when the observation represented by this single record was made), expressed as decimal hours from midnight, local time (e.g., 12. = noon, 13.5 = 1:3pm).
TimeObservationsEnded The time of day the entire observation event ended (this may be different from the time when the observation represented by this single record was made), expressed as decimal hours from midnight, local time (e.g., 12. = noon, 13.5 = 1:3pm).
