適用范圍：This part of ISO/IEC 21000 describes a Rights Data Dictionary which comprises a set of clear, consistent,structured, integrated and uniquely identified Terms (as defined in Clause 5.4) to support the MPEG-21 RightsExpression Language (REL), ISO/IEC 21000-5. Annex A specifies the methodology for and structure of the RDDDictionary, and specifies how further Terms may be defined under the governance of a Registration Authority,requirements for which are described in Annex C.Taken together, these specifications and the RDD Dictionary and Database together make up the RDD System.Use of the RDD System will facilitate the accurate exchange and processing of information between interestedparties involved in the administration of rights in, and use of, Digital Items, and in particular it is intended to supportISO/IEC 21000-5 (REL). Clause 6 describes how this part of ISO/IEC 21000 relates to ISO/IEC 21000-5.As well as providing definitions of Terms for use in ISO/IEC 21000-5, the RDD System is designed to support themapping of Terms from different namespaces. Such mapping will enable the transformation of metadata from theterminology of one namespace (or Authority) into that of another namespace (or Authority). Mapping, to ensureminimum ambiguity or loss of semantic integrity, will be the responsibility of the Registration Authority,requirements for which are specified in Annex C. Provision of automated Term look-up is also a requirement.The RDD Dictionary is a prescriptive Dictionary, in the sense that it defines a single meaning for a Termrepresented by a particular RddAuthorized TermName, but it is also inclusive in that it can recognize theprescription of other Headwords and definitions by other Authorities and incorporates them through mappings. TheRDD Dictionary also supports the circumstance that the same name may have different meanings under differentAuthorities. ISO/IEC 21000-6 describes audit provisions so that additions, amendments and deletions to Terms andtheir attributes can be tracked.ISO/IEC 21000-6 recognises legal definitions as and only as Terms from other Authorities that can be mapped intothe RDD Dictionary. Therefore Terms that are directly authorized by the RDD Registration Authority neither definenor prescribe intellectual property rights or other legal entities.
