Abstract
Abstract In a computer system having a user interface, a memory and a database, a repository program operating in the computer system for accessing the database, the repository program executing a method for treating a group of objects as a single object. This method comprises the steps of retrieving a collection of references for a type from the repository; sorting out each reference in the collection of references that are composite references and have a versioned object type; for each sorted reference, retrieving objects from the reference; and calling up current operations for each retrieved object.

Claim 1
Independent Claim
221 words
In a computer system having a user interface, a memory and a database, a repository program operating in said computer system for accessing said database, said repository program executing a method for updating each object in a reference to latest version of said object, said method comprising the steps of: a. starting a database transaction; b. setting a boolean flag, updatedFlag to false; c. reserving said object and saving a new object as ghostObject; d. retrieving a collection of references for type of said object; e. retrieving objects in each reference found in step d hereof; f. finding latest version of each object retrieved in step e hereof on same variant and storing said retrieved object as latestVersion; g. finding previous version of latestVersion if updateType is lastChecked in and latestVersion is a ghostObject and assigning object found to latestVersion; h. performing the steps of this method for said latestVersion if depth update was specified; i. setting value of latestVersion to object returned in step h hereof if an object was returned; j. comparing latestVersion to object and updating ghotstObject with latestVersion and setting updatedFlag to true if they are not the same object; k. committing said database transaction if updatedFlag is true and returning ghostObject; and, l. aborting said database transaction if updatedFlag is false and return a null object.

In a computer system having a user interface, a memory and a database, a repository program operating in said computer system for accessing said database, said repository program executing a method for updating each object in a reference to latest version of said object, said method comprising the steps of: a. starting a database transaction; b. setting a boolean flag, updatedFlag to false; c. reserving said object and saving a new object as ghostObject; d. retrieving a collection of references for type of said object; e. retrieving objects in each reference found in step d hereof; f. finding latest version of each object retrieved in step e hereof on same variant and storing said retrieved object as latestVersion; g. finding previous version of latestVersion if updateType is lastChecked in and latestVersion is a ghostObject and assigning object found to latestVersion; h. performing the steps of this method for said latestVersion if depth update was specified; i. setting value of latestVersion to object returned in step h hereof if an object was returned; j. comparing latestVersion to object and updating ghotstObject with latestVersion and setting updatedFlag to true if they are not the same object; k. committing said database transaction if updatedFlag is true and returning ghostObject; and, l. aborting said database transaction if updatedFlag is false and return a null object.
Claim 3
Dependent Claim

The method as in claim 1 for each object found in steps f and g, performing all steps in claim 5 so as to define a new composite object hierarchy containing the latest version of those objects.
Claim 4
Dependent Claim
200 words
In a computer system having a user interface, a memory and a database, a repository program operation in said computer system for accessing said database, said repository program executing a method for creating a changeable hierarchy of objects comprising the steps of: a. reserving a versioned object; b. retrieving a collection of objects that form a path between said version object and a top object in said hierarchy comprising the steps of: 1) comparing said versioned object against said top object and returning true if both objects are the same; 2) setting a boolean flag, returnValue, to false; 3) retrieving a collection of references for type of said object; 4) examining each reference in said collection of references retrieved in the preceding step hereof and selecting those references whose inverse is a composite reference; 5) retrieving objects found in each of said references selected in the preceding step hereof; 6) performing steps of this method for each object retrieved in step 5) hereof; 7) adding said object to a collection of objects in true was returned in step 6) hereof; 8) setting returnFlag to true if true was returned in step 6) hereof; 9) returning returnFlag and collection of objects.
Claim 5

In a computer system having a user interface, a memory and a database, a repository program operation in said computer system for accessing said database, said repository program executing a method for creating a changeable hierarchy of objects comprising the steps of: a. reserving a versioned object; b. retrieving a collection of objects that form a path between said version object and a top object in said hierarchy comprising the steps of: 1) comparing said versioned object against said top object and returning true if both objects are the same; 2) setting a boolean flag, returnValue, to false; 3) retrieving a collection of references for type of said object; 4) examining each reference in said collection of references retrieved in the preceding step hereof and selecting those references whose inverse is a composite reference; 5) retrieving objects found in each of said references selected in the preceding step hereof; 6) performing steps of this method for each object retrieved in step 5) hereof; 7) adding said object to a collection of objects in true was returned in step 6) hereof; 8) setting returnFlag to true if true was returned in step 6) hereof; 9) returning returnFlag and collection of objects.
Claim 6
Dependent Claim
