Abstract: An Internet of Things (IoT) entity manager receives a first data stream from a first system and identifies an entity associated with the first data stream. The IoT entity manager receives a second data stream from a second system, wherein the second system lacks interoperability with the first system, determines that the second data stream is associated with the entity, and dynamically generates a first virtual entity to represent the entity and to reflect an IoT context captured by the first virtual entity. The IoT entity manager applies a management policy to the first data stream and the second data stream to determine a status of the first virtual entity and provides a notification of the status of the first virtual entity as defined by the policy.
