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 • Sensor. ML • PML • ISO 15926 and SUMO
Simple examples in XML or N 3 Methodology/Ontologies recording a measuring activity: : AM_WC-T_L 123_T 456 a sten: observed_by_device sten: during sten: observing_activity ; : WS_123 ; [ sten: has_nominal_value [ sten: utc_iso 8601 "2007 -02 -05 T 18: 50" ] ] ; sten: observes [ a weather: ambient_air_at_location ; sten: at : L 123 ] ; sten: observes_physical_property weather: has_wind_chill_temperature ; sten: gives_result_record : I_WC-T_L 123_T 456.

Methodology/Ontologies (OWL) set theory and functions (IEEE SUMO) fundamentals about the real world physical quantities and units of measure (ISO 31 and ISO 1000) (ISO 15926) physical objects and their temporal parts (Sensor. ML) ontology for sensors and services ontology for engineering design (ISO 10303) new concepts in S-TEN – features of time histories – BPA application specific ontologies - proprietary ontolog • equipment models • best practice advice • preventive maintenance • alerts examples in S-TEN
Human observation • States and activities – Human observations are about states • Broad fuzzy states, not property values [ sten: temporal. Part. Of : Mill_M-101 ; sten: at. Time [ sten: utc. Iso 8601 "2008 -01 -06 T 10: 00" ] ] a sten: Device. Running. Hot. • Attributed to a person, not a device. : message#9428 { [ sten: temporal. Part. Of : Mill_M-101 ; sten: at. Time [ sten: utc.

Best practice advice • States and activities – Best Practice Advice is about activities • It is a description of a recommended subclass : Service. Mill. Of. Type. M_ABCAfter. Hot. Smell. Report a sten: Class. Of. Activity ; sten: has. Recommended. Sub. Class [ sten: advice "Check the lub oil system, and inspect each bearing externally. Dismantle any with a discoloured exterior. " ]. • A human or a rule can specify that the activity should be : message#9429 { performed. [ sten: temporal. Part. Of : Mill_M-101 ; sten: at. Time [ sten: utc. Iso 8601 "2008 -01 -06 T 10: 00" ] ] sten: requires. Activity. Of. Class : Service. After. Hot. Smell. Report } sten: result. Graph. Given. By [ sten: performed.
