Abstract: An image abstraction engine is provided to characterize scenes like typically found in an urban setting. Specifically buildings and manmade structures have certain characteristic properties that may be abstracted and compressed in a manner that takes advantage of those characteristic properties. This allows for a more compact and computationally efficient abstraction and recognition.

Abstract: Each node of a topological database that represents an information technology environment with multi-tenancy capability represents a configuration item within the environment and is characterized by a tenant authorization rule that indicates a list of tenants that are authorized to access the corresponding configuration. An unrestricted result to an unrestricted query is obtained, the unrestricted query being representable as a sub-graph isomorphism. The unrestricted result includes groups of nodes of the database that satisfy the isomorphism. A tenant query is applied to the unrestricted result to obtain an authorized result, the tenant query being representable by the same sub-graph isomorphism as the unrestricted query. The authorized result includes identification of any of the groups whose component nodes are each characterized by a TAR that authorizes access by the querying tenant. A notification is issued to the querying tenant on the basis of the obtained authorized result.
