The official, citable version of the LRMI 1.1 specification has been moved to its new home on the Dublin Core Metadata Initiative (DCMI) website at the following URL: http://dublincore.org/dcx/lrmi-terms/. A temporary, informative version of the 1.1 specification appears below.

A note on useRightsUrl: this property was not adopted by schema.org. Subsequently schema.org adopted a property called license which encompasses the same functions as useRightsUrl (see below). The license property is likely to be more widely understood by consumers of schema.org mark-up than the LRMI useRightsUrl property.
