<institution-id> Institution Identifier

A externally defined institutional identifier, for example, a publisher-defined identifier or one defined by an ISO standard, such as “ISNI” or “ISLL”.

Usage/Remarks

The Institution Identifier element holds an external identifier, assigned to an institution by a publisher, an archive or library, a consortium or community such as ROR, 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 perform a simple link inside the XML document.

Taxonomy/Ontology Best Practice

If the content of the <institution-id> element is a term from a taxonomy, ontology, term-list, vocabulary, industry glossary, or other known source, then the vocabulary attributes should be used to record that source. This source can be a formal ontology or an informal field of study. Two attributes are used in this Tag Set to identify such a controlled or uncontrolled vocabulary:
vocab
Name of the controlled or uncontrolled vocabulary, taxonomy, ontology, index, database, or similar that is the source of the term. For example, for a subject term, a value might be the IPC Codes (“ipc”) or MESH headings (“mesh”). For an uncontrolled term, the value might be an area of study such as “medical-devices” or merely the word “uncontrolled”.
vocab-identifier
Unique identifier of the vocabulary, such as (but not limited to) a URI or DOI. For example, for Dublin Core (DCC), the identifier may be “http://dublincore.org/documents/2012/06/14/dces/”.
Multiple Institution IDs
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.
Multi-tier Organization 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 an <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 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>.
