<unitid> ID of a Unit

<unitid> is an alpha-numeric text string that serves as a unique reference point or control number for descibed material. It is an important subelement of the <did>. While it may provide location information as a secondary function, it is primarily meant as a logical designation. Other <did> subelements such as <physloc> and <container> should be used to specifically designate the physical location. It is also not the same as the <eadid>, which is the unique identification string for the finding aid.

Attributes

  • ALTRENDER – not required. Use if the content of the element should be displayed or printed differently than the rendering established in a style sheet for other occurrences of the element.
  • AUDIENCE – not required. Use to set whether the element’s contents will be visible to external users or to internal ones. Possible values are: “internal” and “external.”
  • ID – not required. Creates an ID for element. Can be used for linking.
  • COUNTRYCODE – not required. The ISO 3166-1 code for the country in which the described materials are being held.
  • ENCODINGANALOG – not required. May contain information to map this tag to a particular element in another schema.
  • IDENTIFIER – not required. Machine-readable unique identifier containing a value similar to the text content of <unitid>.
  • LABEL – not required. This can be used when a meaningful display label for an element can’t be derived by the stylesheet from its name. It is available in all <did> subelements.
  • REPOSITORYCODE – not required. The unique code used to indicate the repository which has physical control of the described materials. Should be taken from ISO/DIS 15511.
  • TYPE – not required. May be used to indicate the system from which the ID was derived.

The COUNTRYCODE and REPOSITORYCODE attributes are not required, but should be used at in the high-level <did> to comply with ISAD(G) 3.1.1.

Subelements

<unitid> will likely PCDATA. It can also include the following generic subelements: <abbr>, <archref>, <bibref>, <emph>, <expan>, <extptr>, <lb />, <linkgrp>, <ptr>, <ref>, and <title>.

DACS

Use DACS 2.1.3, Local identifier for the value Use DACS 2.1.4, Repository identifier for the REPOSITORYCODE attribute. Use 2.1.5, Country identifier for the COUNTRYCODE attribute. Required. (DACS 2013, pp.14-15) Chapter 2.1 on the DACS site.

Our EAD file so far

Let’s put in a unitid. I’m going to use a REPOSITORYCODE to match the MAINAGENCYCODE in <eadid>.
