n. (abbr. MODS)an XML-based standard for a descriptive bibliographic element setRiley and Shepherd 2009, 105This allows an archives to more easily convert an EAD-encoded finding aid (or part of it), to OAI PMH-compliant Dublin Core or to MODS, for sharing outside the archival community.O’Meara and Stratton 2016, 59MODS was developed as a standard to encode bibliographic information so its fields and elements should be fairly familiar to most archivists. MODS accommodates content similar to that captured in traditional archival description and EAD. MODS can also be used to describe relationships between digital objects.Shepherd 2017, 165Archivists who are digitizing content from an archival collection may wish to convert data for specific items or files into the Metadata Object Description Schmea (MODS) for ingest into their digital library. Mappings between EAD3 and MARC and EAD3 and MODS are available in the Encoded Archival Description Tag Library.Rubinstein 2017, 304The item-level metadata from these digital libraries is often encoded using Dublin Core or the Metadata Object Description Schema (MODS) and encoded at some point in the process as XML.Rubinstein 2017, 311As archivists, we have already made several data modeling decisions. We have chosen standards like EAD, MODS, Dublin Core, or MARC to represent the data we have collected about our material.LoC 2022cMetadata Object Description Schema (MODS) is a schema for a bibliographic element set that may be used for a variety of purposes, and particularly for library applications.
Notes
MODS was created in 2002 and is maintained by the Network Development and MARC Standards Office of the Library of Congress. The schema was designed for multiple purposes, one of which is digital library applications.MODS serves several purposes, including describing and providing access to digital objects through both original description and also existing MARC 21 fields which have been crosswalked to MODS. Other schemas, including Dublin Core and EAD, can be crosswalked to and from MODS.MODS tags are language based, whereas MARC employs numeric tags. Unlike MARC, MODS does not use field and subfield tagging.
