Version Management

After you have created a tool information model, you populate the model with instance data relevant to your software tools. As you continue to develop and maintain these software tools, this instance data is accessed and modified. The ability to view past versions of this instance data can be useful. For example, you could use this information to:

• Reproduce old versions of a software component.
  
  
• Analyze differences between two versions of a software component.
  
  
• Determine how the relationships between various software components have changed from one release of a software tool to the next.

Microsoft® Repository maintains past versions of your instance data.  These past versions are accessible through Microsoft Repository version management and workspace management interfaces.
