About

MODS is a simpler, element-named alternative to MARC for describing resources, common in Islandora, Fedora and digital collection platforms.

The schema imports xml.xsd and xlink.xsd, included here.

Good to know

  • Authority values (marcrelator roles, LCSH subjects) are not checked against their vocabularies.
  • The example is by xmlvalid.com.
