Abstract

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

specifications.

1. Introduction

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.

2. Definition

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.

application/unimarc).

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.
