Name of an institution or organization (for example, university, corporation) with which a contributor is affiliated.


All levels of a multi-tier organization are listed within a single <aff> element; for example, a program, a department, and a university may be part of the same <aff>. Similarly, both a division and a corporation would be inside one <aff>.

Best Practice: In a typical case, the @id attribute of an <aff> element will be pointed to from one or more <contrib> elements, establishing the linkage between them.

Even if the explicitly tagged numbers or symbols for author linkages are preserved in conversion, the ID/IDREF linking mechanism should be maintained or created during conversion.

If an archive wishes to record divisional distinctions made by a publisher, such as an “<institution>” element with “<dept>” and “<office>” sub-elements for the affiliation, the embedded divisions could be converted to this Tag Set using <named-content> elements:

    <institution content-type="edu">
      University of Frostbite Falls
      <named-content content-type="dept">Dept of Campus Security
      <named-content content-type="dept">Dept of Moose and Squirrel
      <named-content content-type="office">Office of the Acting Dean
