                     Language
                 SADL is used to deploy and discover different
                  types of sensors.
                 It is depend on open standard format (XML).
                 SADL Sections:
                        Sensor and Actuator information
                        Interface information
                        Environment Information

                               Description Language
                 MSDL is used to create a standard for sending
                  monitor tasks by the consumers based on XML.
                 MSDL makes use of SADL meta-models to
                        discover required sensors and actuator
                        Activate and/or interact with to achieve a required
                         monitoring request.
                 MSDL categorized into three parts:
                        Monitor session information,
                        SLA, contract information
                        Requested sensors information.
