Document Status: This is a DCMI Usage Board Working Draft.
Description: This document describes processes related to the submission and review of proposed encoding schemes for identifying controlled vocabularies of values.
Date Valid: 2003-05-15

DCMI recognizes that different discourse and practice communities have legitimate, particular needs to be able to select either vocabulary schemes from an array of recognized controlled vocabularies (e.g., thesauri, classification systems, taxonomies, ontologies, and word lists) or encoding schemes that determine the syntactic structure of the values (e.g., date encoding schemes). To promote the greatest degree of interoperablity, DCMI encourages the registration of recognized schemes with DCMI.

DCMI recognizes that in order to promote interoperability through the common assignment of terms from established, publicly recognized controlled vocabularies and encoding schemes, the most critical, immediate need is to provide registration mechanisms for vocabularies for the "Subject" vocabulary.
