CDRI application profile
set of CDRI names that share some common characteristics. A CDRI Application Profile is a grouping mechanism for CDRI names; the functional specification of the application profile includes a set of metadata, comprising the kernel metadata and additional information applicable to that particular genre of object and functional requirements. Each CDRI name is associated with one or more Application Profiles.

CDRI metadata
specific metadata associated with a referent within the CDRI system, based on a structured data model that enables the referent of the CDRI name to be associated with arbitrarily precise metadata to support description and services.

CDRI name
the string that specifies a unique object (the referent) within the CDRI System. Names may consist of alphanumeric characters in a sequence prescribed by the

CDRI syntax
NOTE − The terms “identifier” and “number” are sometimes but not always used in the same sense and are to be avoided where ambiguity might arise. The unqualified use of “CDRI” alone may also be ambiguous: the term should instead always be used in conjunction with a specific noun (CDRI name, CDRI system, etc).

CDRI registration authority
body appointed by the Standardization Administration of China (SAC) to determine registration agencies and provide allocation of CDRI names prefixes.

CDRI registration agencies
bodies appointed by the Registration Authority to provide registering CDRI names and providing the necessary infrastructure to allow registrants to declare and maintain metadata.

CDRI resolution
process of submitting a CDRI name to a network service and receiving in return one or more pieces of current information related to the identified object. e.g., a location (URL) of the object or metadata. This may involve one or more intermediate mapping operations. The resolution may or may not return an instance of the object.
Multiple resolution is the simultaneous return as output of several pieces of current information related to the object, in defined data structures.

CDRI resource metadata declaration (RMD)
form of message designed specifically for the exchange of metadata between CDRI registration agencies to support their service requirements. It is developed by two or more registration agencies in accordance with format and schema specifications e[b]stablished by the Registration Authority.

CDRI syntax
rules for the form and sequence of characters comprising any CDRI name, specifically the form and character of a prefix element, separator, and suffix element.

CDRI system
functional deployment of CDRI names as the application of identifiers in computer sensible form through assignment, resolution, referent description, administration, etc. as prescribed by this standard.

Check digit
