Value Meaning
Text, numbers, or special characters The type of identifier of the cited objects, which may be a standard, book, journal article, etc. This attribute is typically used to name the type of identifier (such as “doi”) or the name of the organization or type of organization that created the identifier (“ISO” or “archive”).

Suggested usage

Best Practice: The values for this attribute are not constrained. Ideally, the first choice should be the type-of-identifier that is an established type (DOIs, ISBN, Standard Designation). If the identifier is not of an established type, name the assigning agency (ISO, ASTM) or type of assigning agency (aggregator, archive, indexing service, standards organization) which assigned the identifier. Potential values include (but are in no way limited to):
aggregator
Identifier assigned by a data aggregator (generally used with elements <object-id>, <issue-id>, and <volume-id>)
archive
Identifier assigned by an archive or other repository (generally used with elements <object-id>, <issue-id>, and <volume-id>)
arxiv

Restriction This is an optional attribute; there is no default.

Suggested usage

Best Practice: The values for this attribute are not constrained. Ideally, the type-of-identifier should be named as an established type (DOI). If the identifier is not of an established type, name the assigning agency (ISO, ASME) or type of assigning agency (aggregator, archive, indexing service, standards organization) which assigned the identifier.
