<abbr> Abbreviation

<abbr> is a generic element which encodes the shortened form of a word or phrase, including acronyms. The @expan attribute may be used to supply the full form of the word or words for indexing or searching, but it is not required.

Within <conventiondeclaration> it is used to specify the code for a thesaurus, controlled vocabulary, or other standard used in creating the EAD description. Best practices recommend using an authorized list of codes, such as the MARC Description Convention Source Codes. It may not be repeated within <conventiondeclaration>, although it may be reused within any other parent element.

<abbr> may be used within <abstract>, <addressline>, <archref>, <author>, <bibref>, <citation>, <container>, <conventiondeclaration>, <date>, <datesingle>, <didnote>, <dimensions>, <edition>, <emph>, <entry>, <event>, <fromdate>, <head>, <head01>, <head02>, <head03>, <item>, <label>, <localtypedeclaration>, <materialspec>, <num>, <p>, <part>, <physdesc>, <physfacet>, <physloc>, <publisher>, <quote>, <ref>, <sponsor>, <subtitle>, <titleproper>. <todate>, <unitdate>, <unitid>, and <unittitle>.
