Entry Identifier |
Definition |
The <Entry_ID> is the unique identifier of the metadata record. The <Entry_ID> is determined by the metadata author and may be identical to identifiers used by the data provider’s data center or organization. For example, the National Snow and Ice Data Center (NSIDC) DAAC identifies their metadata records as NSIDC-xxxx, where xxxx is a numerical designator. Also, the identifier is case insensitive meaning nsidc-xxxx and NSIDC-xxx refer to the same metadata record. |
