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

Human observation
• States and activities– Human observations are about states
• Broad fuzzy states, not property values
• Attributed to a person, not a device.

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.
