This Recommendation | International Standard defines a number of object classes and name forms which may be found useful across a range of applications of the Directory. The definition of an object class involves listing a number of attribute types which are relevant to objects of that class. The definition of a name form involves naming the object class to which it applies and listing the attributes to be used in forming names for objects of that class. These definitions are used by the administrative authority which is responsible for the management of the directory information. Any administrative authority can define its own object classes or subclasses and name forms for any purpose. Administrative authorities may support some or all the selected object classes and name forms, and may also add additional ones. All administrative authorities shall support the object classes which the directory uses for its own purpose (the top, alias and DSA object classes).
