Abstract

The present invention provides a solution to the needs described in the present application through a system and method of using Virtual Labels in conjunction with an existing software configuration management system. The present invention minimizes the identification or meta-data which needs to be written to a source database or source repository whenever a label for a new version of source code needs to be created thereby minimizing the file storage requirements and the network bandwidth for the transmission of replications of the label. The virtual label system makes use of attribute data connected to a label object to record identification meta-data associated with a particular snap-shot of the source code, whereby the attribute data is subsequently used for program builds/releases/new branch development without the need to have the meta-data recorded in every component source file.

a computer system having a processor, a memory, a program in the memory, a display screen and an input/output unit; and

a middleware mechanism residing in the computer system and configured to use a virtual label which comprises instances of a label type object and attributes associated with the label type object which can be used to identify a version object which is related to the label type object, the version object being located in a configuration management system;

wherein the associated attributes include,

a value representing a time of a last change on a branch with which an instance is associated, wherein the branch is associated with at least a portion of a specific version of source code from which the branch is derived and represents a sequence of revisions to the portion;

wherein the instance is associated with a plurality of versions of the portion of the source code.

2. The apparatus of claim 1 wherein the middleware mechanism is coupled to a Rational™

ClearCase™

configuration management system.
