Abstract:
1. A computer implemented method for extending a directory schema independent of schema modification, the method comprising: instantiating, by an application program, a first object instance of a content class comprising a flexible attribute that is based on a complex data type, the first object instance being created in a directory based on the directory schema, the content class and flexible attribute being defined in the directory schema; accessing, by the application program, a first property to the attribute, the first property being operational or data providing in nature, the property having a data type that is independent of the complex data type; and independent of directory schema modification: (a) instantiating a second object instance of the content class, the second object comprising a second flexible attribute that is base on the complex data type; (b) assigning a second property to the second flexible attribute, the second property having a different number of data elements than the first property; and (c) wherein each data element in the first and second properties comprising data such that neither the first or second properties contribute to data sparsity of a directory based on the directory schema.
