Dynamic aliasing of multi-valued binary attributes in directories
Dynamic aliasing of multi-valued binary attributes in a directory. A plurality of binary attribute-values are stored in the directory that in the aggregate form the multi-valued binary attribute. For each binary attribute-value, there is stored metadata describing characteristics of the binary attribute-value with which it is associated. A preference is received from a user of the directory, the preference being based on the characteristics of the multi-valued binary attribute. The preference is associated with at least one binary attribute-value. A set of multi-valued binary attribute-values are associated for the user based on the preference received from the user and the set of multi-valued binary attribute-values are accessed.
1. A method of dynamic aliasing of a multi-valued binary attribute in an LDAP directory, comprising
storing a plurality of binary attribute-values in the directory that in the aggregate form the multi-valued binary attribute;
storing human-readable metadata for each binary attribute-value, each metadata describing characteristics of the binary attribute-value with which it is associated,
assigning human-readable aliases to the binary attributes, and
accessing binary attribute-values associated with the specified preferences using the assigned human-readable aliases, wherein the human-readable metadata for each binary attribute-value includes an index that identifies the location in the directory for the binary attribute-value;
assigning a human-readable distinguished name including an associated index to reference each multi-valued attribute value;
receiving a preference from a user of the directory, the preference being based on the characteristics of the multi-valued binary attribute;
associating the preference with at least one binary attribute-value; and
identifying a set of multi-valued binary attribute-values for the user based on the preference received from the user; and
wherein identifying a set of multi-valued binary attribute-values for the user based on the preference received from the user further comprises building an alias string based on the user preference that identifies a storage location of a value of a multi-valued attribute.
2. The method of claim 1 wherein the user preference specifies an attribute in the metadata of associated multi-valued binary attribute-values that are used to sort the set of multi-valued binary attribute-values.
3. The method of claim 2 wherein the user preference specifies a sort order of the set of multi-valued binary attribute-values.
4. A non-transitory computer readable storage medium comprising a computer-program product, the computer-program product comprising computer-readable program code for dynamic aliasing of a multi-valued binary attribute in a LDAP directory, comprising
program code for storing a plurality of binary attribute-values in the directory that in the aggregate form the multi-valued binary attribute;
program code for storing human-readable metadata for each binary attribute-value, each metadata describing characteristics of the binary attribute-value with which it is associated,
program code for assigning human-readable aliases to the binary attributes, and program code for accessing binary attribute-values associated with the specified preferences using the assigned human-readable aliases, wherein the human-readable metadata for each binary attribute-value includes an index that identifies the location in the directory for the binary attribute-value; and
program code for assigning a human-readable distinguished name including one of the indexes to reference each multi-valued attribute value;
program code for receiving a preference from a user of the directory, the preference being based on the characteristics of the multi-valued binary attribute;
program code for associating the preference with at least one binary attribute-value; and
program code for identifying a set of multi-valued binary attribute-values for the user based on the preference received from the user;
wherein the program code for identifying a set of multi-valued binary attribute-values for the user based on the preference received from the user further comprises program code for building an alias string based on the user preference that identifies a storage location of a value of a multi-valued attribute.
5. The computer program product of claim 4 wherein the user preference specifies an attribute in the metadata of associated multi-valued binary attribute-values and further comprising program code for sorting the set of multi-valued binary attribute-values.
6. The computer program product of claim 5 wherein the program code for sorting further comprises program code for sorting in a sort order specified in the user preference.
7. The computer program product of claim 4 , wherein the program code are stored as computer instructions in a computer readable storage medium in a data processing system, and wherein the instructions are downloaded over a network from a remote data processing system.
8. The computer program product of claim 4 , wherein the computer code are stored as instructions in a computer readable storage medium in a server data processing system, and wherein the instructions are downloaded over a network to a remote data processing system for use in a computer readable storage medium with the remote system.
9. A system of dynamic aliasing of a multi-valued binary attribute in a LDAP directory, comprising
a memory for storing a plurality of binary attribute-values in the directory that in the aggregate form the multi-valued binary attribute;
the memory also storing human-readable metadata for each binary attribute-value, each human readable metadata describing characteristics of the binary attribute-value with which it is associated; including an index that identifies the location in the directory for the binary attribute-value in the binary attribute with which it is associated;
apparatus for assigning human-readable aliases to the binary attributes, and apparatus for accessing binary attribute-values associated with the specified preferences using the assigned human-readable aliases, wherein the human-readable metadata for each binary attribute-value includes an index that identifies the location in the directory for the binary attribute-value; and
apparatus for assigning a human-readable distinguished name including an associated index to reference each multi-valued attribute value;
apparatus for receiving a preference from a user of the directory, the preference being based on the characteristics of the multi-valued binary attribute;
apparatus for associating the preference with at least one binary attribute-value; and
apparatus for identifying a set of multi-valued binary attribute-values for the user based on the preference received from the user,
wherein the apparatus for identifying a set of multi-valued binary attribute-values for the user based on the preference received from the user further comprises apparatus for building an alias string based on the user preference that identifies a storage location of a value of a multi-valued attribute.
10. The system of claim 9 wherein the user preference specifies an attribute in the metadata of associated multi-valued binary attribute-values that are used to sort the set of multi-valued binary attribute-values.
11. The system of claim 10 wherein the user preference specifies a sort order of the set of multi-valued binary objects.
