Encoded Archival Description Tag Library, Version 2002
<unitid> ID of the Unit
Any alpha-numeric text string that serves as a unique reference point or control number for the described material, such as a lot number, an accession number, a classification number, or an entry number in a bibliography or catalog. An important subelement of the Descriptive Identification < did>, the <unitid> is primarily a logical designation, which sometimes secondarily provides location information, as in the case of a classification number. Use other <did> subelements, such as <physloc> and <container>, to designate specifically the physical location of the described materials.
Do not confuse <unitid>, which relates to the archival materials, with <eadid>, which is used to designate a unique identification string for the finding aid.
Although not required, the COUNTRYCODE and REPOSITORYCODE attributes should be used in < unitid> at the <archdesc><did> level to comply with ISAD(G) element 3.1.1. REPOSITORYCODE specifies the ISO 15511 code for the institution that has custody of the materials described, while COUNTRYCODE provides the ISO 3166-1 code for the country in which that institution is located. IDENTIFIER should contain a machine-readable unique identifier, containing a value similar to the text in the <unitid> element. The TYPE attribute may be used to indicate the system from which the <unitid> was derived, e.g., accessioning system, record group classification scheme, records retention scheduling system, etc.
