Specifying “structural constraints” on a description set

the resources that may be described by descriptions in the description set

the properties that may be referenced in statements

the ways a value surrogate may be given

DCMI Description Set Profile (DSP) Description templates Statement templates Templates contain constraints of specified types e.g. Property URI List Vocabulary Encoding Scheme Occurrence Literal List XML format for expressing a DSP

Description templates
