EAD Tag Library for Version 1.0

EAD Elements: <unitid> ID of the Unit

Description:

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.

Use the TYPE attribute to indicate the system from which the <unitid> was derived, e.g., accessioning system, record group classification scheme, records retention scheduling system, etc. The COUNTRYCODE and REPOSITORY CODE attributes are likely to be set only once, at the highest unit level <archdesc><did><unitid>, with the values inherited by the Component <c> levels.

May contain:

#PCDATA, abbr, archref, bibref, emph, expan, extptr, extref, lb, linkgrp, ptr, ref, title

May occur within:

archref, dentry, did
