S-TEN Intelligent Self-describing Technical and Environmental Networks

The S-TEN project aims to develop intelligent self-describing networks for technical and environmental data. Partners will use methodologies and ontologies to capture and record data in XML or N3 format, enabling efficient data analysis and sharing. The project is funded by the European Union and will last for 2.5 years.

  4. Methodology/Ontologies • Schemas • Physical things • objects and activities • whole-part and involvement relationships • Temporal part and time • Observation and measurement • observation activities, devices and results • Physical quantity, property and unit • Information • carrier (file or signal) and content • Other standards • SensorML • PML • ISO 15926 and SUMO

  5. PTO Methodology/Ontologies Simple examples in XML or N3 recording a measuring activity: :AM_WC-T_L123_T456 a sten:observing_activity ; sten:observed_by_device :WS_123 ; sten:during [ sten:has_nominal_value [ sten:utc_iso8601 "2007-02-05T18:50" ] ] ; sten:observes [ a weather:ambient_air_at_location ; sten:at :L123 ] ; sten:observes_physical_property weather:has_wind_chill_temperature ; sten:gives_result_record :I_WC-T_L123_T456 .

  6. Methodology/Ontologies Simple examples in XML or N3 recording a measurement result: :I_WC-T_L123_T456 { [ sten:temporal_part_of [ a weather:ambient_air_at_location ; sten:at :L123 ] ; sten:at_time [ sten:utc_iso8601 "2007-02-05T18:50" ] ] weather:has_wind_chill_temperature [ bipm:celsius [ basics:decimal "-25.0" ] ] }

  7. Methodology/Ontologies wind speed sensor temperature sensor wind speed measurement activity temperature measurement activity record of temperature record of wind speed wind chill calculation activity record of wind chill record of wind chill and time clock wind chill and time record combining activity record of time time measurement activity wind chill and time measurement activity

  8. Methodology/Ontologies temperature sensor wind speed sensor record of temperature record of wind speed processor/ transmitter record of wind chill record of wind chill and time record of time clock wind chill and time measurement device

  9. Methodology/Ontologies (OWL) set theory and functions (IEEE SUMO) fundamentals about the real world physical quantities and units of measure (ISO 15926) physical objects and their temporal parts (SensorML) ontology for sensors and services (ISO31 and ISO 1000) ontology for engineering design (ISO 10303) new concepts in S-TEN – features of time histories – BPA application specific ontologies - proprietary ontologies • equipment models • best practice advice • preventive maintenance • alerts examples in S-TEN

  10. [ sten:temporalPartOf :Mill_M-101 ; sten:atTime [ sten:utcIso8601 "2008-01-06T10:00" ] ] a sten:DeviceRunningHot . :message#9428 { [ sten:temporalPartOf :Mill_M-101 ; sten:atTime [ sten:utcIso8601 "2008-01-06T10:00" ] ] a sten:DeviceRunningHot } sten:resultGraphGivenBy [ sten:performedBy mailto:fred.bloggs@www.a.d.vance.co.uk ] . Human observation • States and activities • Human observations are about states • Broad fuzzy states, not property values • Attributed to a person, not a device.

Dismantle any with a discoloured exterior." ] . :message#9429 { [ sten:temporalPartOf :Mill_M-101 ; sten:atTime [ sten:utcIso8601 "2008-01-06T10:00" ] ] sten:requiresActivityOfClass :ServiceAfterHotSmellReport } sten:resultGraphGivenBy [ sten:performedBy mailto:fred.bloggs@www.a.d.vance.co.uk ] . Best practice advice • States and activities • Best Practice Advice is about activities • It is a description of a recommended subclass • A human or a rule can specify that the activity should be performed.
