In the present description the term "directory" means a table of names and corresponding items of data. Data in a directory is locational or directive in nature, e.g., (1) a listing of names, addresses, and other data about a specific group of persons or organizations, or (2) an index that is used by a control program to locate one or more blocks of data stored in separate areas of a data set in direct access storage, or (3) an index to locate blocks of program information. The user of a directory knows the definition of the object references by a name, but needs the specific data value(s), e.g., phone number, in order to perform a specific activity. Described here is a Directory Internal Exchange Protocol which provides communications between various components of the directory or Directory Service Units (DSUs).
