A subprovider is a Rational® CM API extension package that is created for a supported product. The subproviders connect to the Rational CM API provider and represent defined resources stored in each integrated product. Each subprovider maps an integrated product object hierarchy to the Rational CM API object model hierarchy.
With the Rational CM API the client has the ability to configure, integrate, and synchronize repositories or resources (for example, between ClearQuest® and ClearCase).
