Abstract

Abstract A generalized directory data model is provided for use in storing, in a directory database, mappings of information related to names and the like, the directory data base being a set of directories containing information of a similar type. The directory data model includes a user data component; a user data descriptor component; and an operation control block component; the user data component providing a model for collection of user data elements; the user data descriptor component describing the user data component and containing data element format information, identification and allocation information, and data access control information; and the operation control block component containing information for controlling those directory system functions to be performed on behalf of a particular user, the operation control block component including search and update algorithm control information and internal tables defining the relationship of the particular member user directory with other member user directories within a particular directory database.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 152 words
A generalized directory data model for use in storing, in a directory database, mappings of information related to names and the like, said directory database being a set of directories containing information of a similar type, said directory data model including : a user data component; a user data descriptor component; and an operation control block component; said user data component providing a model for collection of user data elements; said user data descriptor component describing said user data component and containing data element format information, identification and allocation information, and data access control information; and said operation control block component containing information for controlling those directory system functions to be performed on behalf of a particular user; said operation control block component including search and update algorithm control information and internal tables defining the relationship of the particular member user directory with other member user directories within a particular directory database.
Claim 2
Dependent Claim 152 words
A generalized directory data model for use in storing, in a directory database, mappings of information related to names and the like, said directory database being a set of directories containing information of a similar type, said directory data model including : a user data component; a user data descriptor component; and an operation control block component; said user data component providing a model for collection of user data elements; said user data descriptor component describing said user data component and containing data element format information, identification and allocation information, and data access control information; and said operation control block component containing information for controlling those directory system functions to be performed on behalf of a particular user; said operation control block component including search and update algorithm control information and internal tables defining the relationship of the particular member user directory with other member user directories within a particular directory database.
Claim 3
Dependent Claim 32 words
Apparatus in accordance with Claim 1 in which said internal tables define whether said particular user directory is a subordinate, a superior or a peer in relation to said other user directories.
Claim 4
Dependent Claim 38 words
Apparatus in accordance with Claim 1 in which said search and update algorithm information determines the actions to be taken by each of said directories when a "not found" condition occurs at any given one of said directories.
Claim 5
Dependent Claim 32 words
Apparatus in accordance with Claim 1 in which said operation control block contains integrity parameter information which determines the degree of further propagation of a directory update from each of said directories.
Claim 6
Dependent Claim 28 words
Apparatus in accordance with Claim 4 in which said integrity parameter information instructs one or more of said directories to propagate a directory update to all other directories.
Claim 7
Dependent Claim 27 words
Apparatus in accordance with Claim 4 in which said integrity parameter information instructs one or more of said directories not to propagate a directory update any further.
