ISO 2146 (Registry Services for Libraries and Related Organisations) is an international standard currently under development by ISO TC46 SC4 WG7 to operate as a framework for building registry services for libraries and related organisations. It takes the form of an information model that identifies the objects and data elements needed for the collaborative construction of registries of all types. It is not bound to any specific protocol or data schema. The aim is to be as abstract as possible, in order to facilitate a shared understanding of the common processes involved, across multiple communities of practice.
ANSI/NISO Z39.50 (=ISO 23950: "Information Retrieval (Z39.50): Application Service Definition and Protocol Specification") specifies a client/server-based protocol for
searching and retrieving information from remote databases.
