A computer method, system and apparatus for selecting version of a software program artifact includes history means and processor means. The history means indicate (a) a baseline version of each artifact in a given plurality of artifacts forming a subject software program configuration, and (b) respective change-set information per artifact. Different change sets correspond to different versions of the artifacts. The processor means determine version of an artifact in the subject software program configuration using the indicated baseline versions and change-set information. The processor means enable the configuration management system to display the determined version of the artifact to a user.

Computer method and apparatus for activity-based version selection in a configuration management system

Described is a method for migrating versioned data from a source configuration management system to a target configuration management system. The method includes determining, for at least one historical period having versioned data items to be migrated from the source to target systems, an earliest versioned data item based on a start time for the historical period. At least one subsequent versioned data item is determined based on a sampling interval and an end time for the historical period. The earliest versioned data item and subsequent versioned data items for each historical period are migrated from the source configuration management system to the target configuration management system. Advantageously, migration is performed faster than if all existing versions are migrated and storage requirements are reduced. In addition, differencing tools in the target system can compare different versions of the migrated data items.

Migration of versioned data between configuration management systems

Computer method and apparatus for managing configurations of programming models is disclosed. A software development workspace respective to a user holds a programming model configuration specified by the user. The configuration is formed of one or more model elements. For each user workspace, one or more change-flow hierarchies define flow of changes to model elements.
