Metadata Object Description Schema (MODS)

XML metadata standard with release-specific schema documents.

Identity and normative owner

Record: mods; record authority: Modeling. Normative owner of subject: Library of Congress and the standard's maintenance activity. Resource reference: https://www.loc.gov/standards/mods/mods-schemas.html Registration is for discovery, not adoption, endorsement, or transfer of normative ownership.

Editions

  • 3.8: named release; current status not reverified. Named edition for identification, not a claim that it is the newest edition.

Distributions and references

  • mods-documentation — documentation, text/html, en.
  • mods-schema-reference — schema, application/xml, en. Rights are assessed per distribution in the record. Unassessed rights do not imply permission to redistribute.

Verification scope

  • metadata-observed (2026-09-17): Primary-source page metadata observed; no distribution bytes, legal clearance, current-latest guarantee, or implementation conformance was verified.

Cautions

  • Keep the abstract standard, named release, XSD file, documentation, and retrieved bytes distinct.
  • Other releases may be registered without changing the identity of this record.
