1. A system comprising: a processor; and a memory coupled to the processor, the memory storing instructions executable by the processor to: retrieve, at a first context sensor associated with a first information object, first contextual information from a source distinct from the first context sensor, wherein the first contextual information comprises domain-independent information associated with the first information object, and wherein the first information object corresponds to a first mission plan; generate second contextual information based on application of a first derivation rule to the first contextual information, wherein the second contextual information comprises first domain-specific information associated with the first information object, and wherein the second contextual information indicates a change to the first mission plan; add the second contextual information to the first information object; transmit the second contextual information from the first context sensor to a second context sensor associated with a second information object, wherein the first context sensor is distinct from the second context sensor, and wherein the first information object is distinct from the second information object, and wherein the second information object corresponds to a second mission plan; generate third contextual information based on application of a second derivation rule to the second contextual information, wherein the third contextual information comprises second domain-specific information associated with the second information object, and wherein the third contextual information indicates a constraint on the second mission plan caused by the change to the first mission plan; transmit the third contextual information from the second context sensor to the first context sensor; and generate fourth contextual information based on application of a third derivation rule to the third contextual information, wherein the fourth contextual information comprises third domain-specific information associated with the first information object.
