<institution-id> Institution Identifier

A externally defined institutional identifier, whether organization-specific (for example, “IEEE”) or from an established identifying authority (for example, “Ringgold” or “ISNI”).

Usage/Remarks

Used with an Institutional Name

A wrapper element named <institution-wrap> holds both the name of an institution (<institution>) and any identifiers for that institution (<institution-id>), for example, an INSI or Ringgold ID.
External Identifier
The <institution-id> 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 construct a simple in-document link.
Multiple Identifiers
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 may be 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>). Alternatively, a divisional distinction such as an “organization” element with a 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>.
