9. The system of claim 7 wherein translating the plurality of domain level RFID system constraints comprises generating metadata including the RFID system level constraints.
7. A Radio Frequency Identification (RFID) system comprising: one or more computers; a domain level constraint generator software component, operable on said one or more computers, to receive, from a first user, a plurality of domain level RFID system constraints, wherein the domain level RFID system constraints are applicable across one or more components of the RFID system; a translator software component, operable on said one or more computers, to translate the plurality of domain level RFID system constraints into RFID system level constraints, wherein the RFID system level constraints are applicable across the RFID system as a whole; and system level software, operable on said one or more computers, to control the RFID system using the RFID system level constraints, the system level software receiving an RFID system incident generated in response to RFID data and forwarding the RFID system incident to the domain level constraint generator software component, wherein the domain level constraint generator software component modifies the domain level RFID system constraints in response to the RFID system incident, and wherein the domain level constraint generator software component translates the modified domain level RFID system constraints into modified RFID system level constraints to control the system level software.
