This document defines a framework for the extensible registration of information — an approach used to manage an information register. This framework specifies the following requirements of an information register: capability requirements that an information register uses to manage register content; governance requirements that define a set of processes and rules used in the establishment, management, operation, content publication and use of an information register. The following considerations are out of scope of this document: implementation details for the realization of an information register; content and related definitions that are managed within an information register.
