US Patent 7685167 Configuration management database reference instance

A reference instance for use in a configuration management system is a configuration item that may be associated with a number of assets, all of which share a common set of attributes. The use of reference instances permits a single configuration item to identify a potentially large number of assets. This may be particularly useful for identifying and tracking low-priority assets where the detail or amount of information needed to effectively track and manage the asset is relatively small. Use of reference instance configuration items allows an organization to identify and manage virtually all of their assets without the cost and effort of creating large numbers of substantially identical configuration items.
