(standard, communications) The ITU-T and ISO international standard for electronic directory services that store and serve (to clients using a variety of interfaces) centrally-managed personal location information. The standard defines a hierarchical directory structure for administrative domains (organization, divisions, departments and workgroups). Examples: white pages, Knowbot, WHOIS.

An OSI standard that defines where to find the address to put the electronic envelope of an X.400 transmission. X.500 is the directory of names and addresses similar to a telephone directory.
Specification of the directory service required to support X.400 e-mail.
A standard which defines electronic mail directory services. Mostly used in Europe.
A standard that defines how global directories should be structured.
A directory standard that lets applications like e-mail access information which can either be central or distributed. The benefit of a directory is the ability to minimize the impact on the user of changes to a network. The standard is broken down under subsequent numbers
(including DAP). Directory Access Protocol developed by the ITU, is a standard for global directory services. X.500 defines object classes for a directory and a method for accessing names from a directory. The DAP X.500 protocol supports generalized browsing, directory administration, schema management, full authentication, and the infrastructure for internationalization.

A directory access protocol to enable a common standard for directories of information over a network. It has never caught on as well as its designers intended. See LDAP.
A protocol defining standards for directory services in an open network.
An overall model for distributed directory services. The model encompasses the overall namespace and the protocol for querying and updating it. The protocol is known as DAP (Directory Access Protocol).
A distributed directory interface allowing different vendors to store and access information on different systems.
The International Telegraph and Telephone Consultative Committee standard for directory services.
A comprehensive but cumbersome directory information model. Many directories are derived from X.500 (e.g., AD) but are not fully X.500 compliant.

Another complex standard, this time for managing directories of people, either on the World Wide Web or on private networks.

X.500 is a series of computer networking standards covering electronic directory services. The X.500 series was developed by ITU-T, formerly known as CCITT. The directory services were developed in order to support the requirements of X.400 electronic mail exchange and name lookup.
