This memorandum provides a mechanism for representing objects which
are files of Machine-Readable Cataloging records (MARC). The MARC
formats are standards for the representation and communication of
bibliographic and related information. A MARC record contains
metadata for an information resource following MARC format
The MARC formats are sets of codes and content designators defined
for encoding metadata for five types of data: bibliographic,
holdings, authority, classification, and community information. The
structure of MARC records is an implementation of national and
international standards, ANSI Z39.2 (Information Interchange Format)
and ISO 2709 (Format for Information Interchange). Codes and
conventions in the formats identify and characterize data elements
within a record and support the manipulation of those data.
MARC formats are communication formats, primarily designed to provide
specification for the exchange of bibliographic and related
information between systems. They are widely used in a variety of
exchange and processing environments. They do not mandate internal
storage or display formats to be used by different systems.
Since there are different flavors of MARC which would be processed by
different applications, this content-type/subtype refers to the
harmonized USMARC/CANMARC specification. Additional content-
types/subtypes may be defined in the future (e.g.
MARC records involve three elements: the record structure, content
designation, and data content. Only those records that contain all
three elements according to the standard would use this content-
type/subtype, i.e. content extracted from the structure would not.
Since MARC does not mandate an internal storage format, parameters
have not been assigned to specific implementations (e.g. OCLC-MARC,
LC-MARC, etc.). In addition, parameters have not been defined for
the specific type of MARC format (e.g. bibliographic, authority,
holdings), since the information is contained in the Leader portion
of the record.
