1. Introduction

This mapping provides equivalencies between data elements in MODS and those in MARC 21. Initially, a MODS record is converted to MARCXML. Further conversion work is required to create a MARC 21 (ISO 2709) record. Since MARC 21 includes many more data elements than MODS, this mapping suggests a single MARC 21 equivalent for each MODS element, although there may be other equivalents. The MARC 21 to MODS mapping provides multiple MARC 21 data elements appropriate for a given MODS element.

This document is intended for use in first converting a MODS record to MARCXML and then to a MARC 21 (ISO 2709) record. Since MODS data is not as granular as MARC 21 data and some MARC 21 subfields are concatenated into one MODS field, some data may map to inappropriate MARC 21 fields or subfields. Consequently, some conversions will result in some loss of data identification.

NOTE: Those MARC elements that have multiple positions (008/24-27BK, SE, 008/30-31, MU) allow for multiple genre codes. If more than one instance of <genre> place in succeeding positions until positions exhausted. If more codes than positions, leave out subsequent ones.

4. Leader and Fixed Fields

A MARC 21 record requires a Leader and field 008 (Fixed-Length Data Elements). Certain character positions in each of these fixed-length fields will need coding, although most will generate default values.

Leader -- Data elements that provide information for the processing of the record. The data elements contain numbers or coded values and are identified by relative character position. The Leader is fixed in length at 24 character positions (00-23) and is the first field of a MARC 21 record. Converted records should include a Leader as follows:

00-04 - Logical record length
  computer-generated, five-character numeric string
05 - Record status
  set to "n" (new)
06 - Type of record
  see above under <typeOfResource>
  if none indicated set to "a" (language material)
07 - Bibliographic level
  if <originInfo><issuance>="monographic, set to "m" (monograph/item)
  if <originInfo><issuance>="continuing", set to "s" (serial)
  if <typeOfResource> with attribute "collection=yes", set to "c" (collection)
Only one value may be used; if more than one of the above values is in a MODS record, consider this in priority order; if none of these values are indicated, set to "m"
08 - Type of control
  set to "blank"
09 - Character coding scheme
  set to "blank"
10 - Indicator count
  set to "2"
11 - Subfield code count
  set to "2"
12-16 - Base address of data
  computer-generated five-character numeric string
17 - Encoding level
  set to "u"
18 - Descriptive cataloging form
  set to "u"
19 - Linked record requirement
  set to "blank"
20-23 - Entry map
  set to "4500"

008: Fixed-length data elements
Establish appropriate 008 according to <typeOfResource> as indicated above. Fill in character positions as follows:

008/00-05 - Date entered on file
  -- see <recordInformation> <recordCreationDate encoding="marc">
  -- if not present, generate a six-character numeric string representing the day the MARC 21 record was created using the following format: yymmdd.
008/06 - Type of date/publication status
  -- if <originInfo><issuance="monographic"> and <dateIssued> is not repeated, set to "s" (single known date/probable date)
  -- if <originInfo><issuance="monographic"> and <dateIssued point="start">, set to "m" (multiple dates)
  -- if <originInfo><issuance="monographic"> and <dateIssued point="end">, set to "m" (multiple dates)
  -- if <originInfo><issuance="continuing"> and <dateIssued point="end" encoding="marc">=9999, set to "c" (continuing resource currently published)
  -- if <originInfo><issuance>="continuing" and <dateIssued point="end" encoding="marc">=[some date], set to "d" (continuing resource ceased publication)
  -- if <originInfo><issuance="continuing"> and <dateIssued point="end" encoding="marc">=uuuu, set to "u" (continuing status status unknown)
  -- if <originInfo> includes <dateIssued> without <issuance>, set to "s" (single known date/probable date)
  -- if <originInfo> includes <dateIssued encoding="marc">, set to "s" (single known date/probable date)
  -- if no data in <dateIssued>, set to fill (|)
008/07-14 - Date 1/Date 2
  -- see above under <originInfo><dateIssued>
  -- if no data, set to fills (|)
008/15-17 - Place of publication, production, or execution
  -- see above under <originInfo><place><placeTerm type="code authority="marccountry">
  -- set as specified above under <genre> and <targetAudience>
  -- set unused character positions to fills (|)
  --set to fills (|)
