An approach is provided for managing projection and injection operations on information spaces with respect to their information content. An information space projection module receives a query to project a first information space from a second information space. In response to the query, the module extracts a subset of information content from the second information space by using a partitioning function. The module also extracts a subset of rules from the second information space by using the partitioning function. The module then creates the first information space using the extracted subset of information content, and the extracted subset of rules while maintains a link between the first and the second information spaces. An information space injection module enables further injection of the first information space back into the second information space.
