Record Syntax Object Identifiers for Specific MARC Formats

The following registration scheme for specific MARC formats was approved at the March 1999 ZIG meeting.

For each general MARC format listed above, the following specific formats are automatically registered, subordinate to the object identifier for the general format, 1.2.840.10003.5.x
  1. bibliographic
  2. authority
  3. holdings
  4. community information
  5. classification
Thus for example for Marc21, the following are registered:

Object Identifier Name Reference
1.2.840.10003.5.10.1 USMARC bibliographic USMARC Concise Format for Bigliographic Data
1.2.840.10003.5.10.2 USMARC authority USMARC Concise Format for Authority Data
1.2.840.10003.5.10.3 USMARC holdings USMARC Concise Format for Holdings Data
1.2.840.10003.5.10.4 USMARC community information USMARC Concise Format for Community Information
1.2.840.10003.5.10.5 USMARC classification USMARC Concise Format for Classification Data

When the general object identifier (e.g. 1.2.840.10003.5.10) is used it identifies the general MARC format (e.g. Marc21) and the specific format is unspecified. Thus an origin may specify Marc21 as the preferred record syntax on a Present request, and the response might include records of any of the five specific formats; or the origin might specify Marc21 Bibiliographic as the preferred record syntax, and the response might be limited to bibliographic records only.

The following Extension to this scheme was approved December 2002

Additional format types (beyond the five listed above) may be registered subordinate to 1.2.840.10003.5.x.100. An individual representing the format 1.2.840.10003.5.x may request to be designated by the maintenance agency as the registration agent for assignments subordinate to the oid 1.2.840.10003.5.x.100. (For example, a representative of the Danmarc format could be designated as registration authority to assign object identifiers subordinate to 1.2.840.1003.5.14.100, and for example might register "Extended Danmarc" as 1.2.840.10003. If a second individual requests to register format types for the same format, that individual would be designated agent for 1.2.840.10003.5.x.101, and so on. The following assignments have been made to date:

  • The two oid nodes 1.2.840.10003.5.109 and 1.2.840.10003.5.110 are allocated to mime types:
    • iana mime types are registered subordinate to 1.2.840.10003.5.109
    • Z39.50 mime types ate registered subordinate to 1.2.840.10003.5.110
  • A mime type may be registered as a Z39.50 mime type when there is no current appropriate iana type. When a mime type is so registered it is with the understanding that that registration will be depricated if and when an appropriate mime type is defined by iana, and it will be superceded by a subsequent registration in the iana category.
