All Rights Reserved. + +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. + + + + + + + + +Guenther Informational [Page 1] + +RFC 2220 Application/MARC Content-type October 1997 + + +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. + +3.

The base64 content-transfer-encoding is + recommended for transmission of MARC over electronic mail. + +4. Security Considerations + + There are no known security risks associated with the use or viewing + of MARC data. A MARC record may have security classification + associated with the document it describes or metadata in that record. + Although this does not present any security risk to the user of MARC + data, it may provide an opportunity for a security breach for the + source of classified MARC data. + + + + + + + + +Guenther Informational [Page 2] + +RFC 2220 Application/MARC Content-type October 1997 + + +5.
