## Abstract

A network device receives a plurality of framework definitions corresponding to a respective plurality of device platforms, wherein each of the device platforms comprises at least one device. The network device generates a plurality of generalized framework definitions for each of the plurality of device platforms, wherein the plurality of generalized framework definitions comprise basic linguistic components corresponding to elements in the respective plurality of framework definitions. The network device receives data from the at least one device for each of the device platforms. The network device extracts data from the received data based on the plurality of generalized framework definitions. The network device automatically identifies contexts that include at least one device for each of the at least two device platforms based on the extracted data. The network device transmits instructions to the at least one device for each of the at least two device platforms based on one of a rule or a request associated with the identified one or more contexts.
