A externally defined institutional identifier, whether publisher-specific (for example “AIP”) or from an established identifying authority (for example, “Ringgold” or “ISNI”).
A single institution may have multiple identifiers, either because different assigning agencies have defined an identifier or because the entity belongs to more than one larger organizational unit, for example, a laboratory may be part of multiple institutions.
Common Practice: All levels of a multi-tier organization are typically listed within a single <institution> element and given a single institution identifier. For example, a program, a department, and a university may be part of the same <institution>, inside a single <institution-wrap> with a single <institution-id>. Similarly both a corporation and a division within the corporation might be inside one <institution> element, inside a <institution-wrap> with a single institution identifier (<institution-id>.
<institution-wrap> <institution-id>Moo-U-41</institution-id> <institution content-type="edu"> University of Frostbite Falls, Dept of Campus Security, Dept of Moose and Squirrel Security, Office of the Acting Dean</institution> </institution-wrap>
Alternatively, a divisional distinction such as an “organization” element with subordinate “dept” and an “office” inside a department could tagged using multiple <institution> elements with the @content-type attribute differentiating institution, department, and office. Each of these divisions could be assigned an institutional identifier (<institution-id>), which would require the wrapper element <institution-wrap>.
<institution-wrap>
<institution content-type="edu">
University of Frostbite Falls</institution>
<institution-id>Moo-U-41</institution-id>
</institution-wrap>
<institution-wrap>
<institution content-type="dept">
Dept of Campus Security</institution>
<institution-id>dept-42s</institution-id>
</institution-wrap>
<institution-wrap>
<institution content-type="dept">
Dept of Moose and Squirrel Security</institution>
<institution-id>rcky-n-bllw</institution-id>
</institution-wrap>
<institution-wrap>
<institution content-type="office">
Office of the Acting Dean</institution>
<institution-id>4850ws</institution-id>
</institution-wrap>External Identifier: The element holds an external identifier, assigned to an institution by a publisher, an archive or library, or an agency such as Ringgold or ISNI. The contents of this element should not be confused with the @id attribute, which holds an internal document identifier that can be used by software to preform a simple link.
