MODS (Metadata Object Description Schema)

Relationships to other metadata standards

• This scheme is a profile of MARC (Machine-Readable Cataloging).

• This scheme can be mapped to Dublin Core.

  This document gives equivalencies between the elements in the Metadata Object Description Schema (MODS) and the Dublin Core Metadata Element Set, version 1.1. One application of the mapping might be to expose MODS records for OAI harvesting in Dublin Core syntax.

• This scheme can be mapped to MARC (Machine-Readable Cataloging).

  This document is intended for use in first converting a MODS record to MARCXML and then to a MARC 21 (ISO 2709) record. MARC 21 includes many more data elements than MODS, so although this mapping suggests a single MARC 21 equivalent for each MODS element, there may be other equivalents that are more appropriate for particular pieces of information. Additionally, MARC 21 is more granular than MODS so some data may map to inappropriate MARC 21 fields or subfields. Consequently, some conversions will result in some loss of data identification.

• This scheme can be generated from MARC (Machine-Readable Cataloging).

  This document is intended for use in converting MARC 21 bibliographic records to MODS. Where multiple subfields are specified or implied in MARC, data will be concatenated with a space substituted for the subfield delimiter and subfield code. Where multiple MARC fields correspond to a single MODS element, each will be mapped to a separate instance of the element (with subfields concatenated). Because of this, it is not generally possible to perform a round-trip conversion without loss of specificity.
