Glossary¶
- bibliographic item¶
Document metadata for purposes of referencing or citing. Corresponds to
BibliographicItem
instance.- citation¶
Sometimes not quite correctly used as a synonym for bibliographic item.
- resource identifier¶
- document identifier¶
- docid¶
Identifier of a resource (a document, a registry, or otherwise).
A resource can have multiple identifiers (e.g., a DOI, an ISBN, etc.), and sometimes a single identifier can be shared by multiple resources (however, such an ambiguous identifier should not be primary, that would be a data integrity issue).
Identifiers are listed under
BibliographicItem.docid
, and each identifier is arelaton.models.bibdata.DocID
instance in Python.- primary resource identifier¶
- primary document identifier¶
Main characteristics of a primary identifier:
Its
id
can be used to unambiguously reference the document (resource).A primary identifier is expected to be universally unique to this resource.
This service displays primary identifiers without identifier types, as types tend to be self-explanatory.
The
id
value of a primary identifier uses format more or less similar to NIST’s PubID (possibly the only strongly standardized identifier format). It always starts with a prefix that denotes schema/document family.In Python, such identifiers have their
primary
attribute set toTrue
.- resource identifier type¶
- document identifier type¶
- docid.type¶
The
type
component of document identifier, contained indocid[*].type
field of bibliographic item’s Relaton representation (fieldtype
in Python).Document identifier type in Relaton is a somewhat murky concept. In case of a primary document identifier, its type tends to be used to reference a namespace or registry (e.g., DOI, ISBN), and in other cases used to reference a publishing organization (e.g., IETF, IANA).
Examples:
IETF
,IEEE
,DOI
.- docid.id¶
A string that is used to identify a resource within the domain (schema, namespace, etc.) designated by docid.type.
