Domains and ranges included for the new properties: hasProperty/isPropertyOf and hasMeasurement/isMeasurementOf.

- saref:accomplishes: A relationship between a certain entity (e.g., a device) and the task it accomplishes
From this definition, it is unambiguous that the object of a saref:accomplishes relationship is always a task.

  - domain is saref:Command and range is saref:State
- saref:actsUpon - A relationship between a command and a state
  - domain saref:Command, range saref:State
- saref:controlsProperty - A relationship specifying the Property that can be controlled by a certain Device
  - domain saref:Device, range saref:Property
- saref:hasCommand - A relationship between an entity (such as a function) and a command
  - domain saref:Function and range saref:Command
- saref:hasFunction - A relationship identifying the type of function of a device
  - domain saref:Device and range saref:Function

- saref:isOfferedBy - A relationship between a service and a device that offers the service
  - domain saref:Service and range saref:Device
- saref:makesMeasurement - A relation between a device and the measurements it makes. Such measurement will link together the value of the measurement, its unit of measure and the property to which it relates.
  - domain saref:Device and range saref:Measurement
- saref:measuresProperty - A relationship specifying the Property that can be measured by a certain Device
  - domain saref:Device and range saref:Property
- saref:offers - A relationship between a device and a service
  - domain saref Device and range saref:Service
- saref:relatesToMeasurement - A relationship between a property and the measurements it relates to
  - domain saref:Property and range saref:Measurement
- saref:relatesToProperty - A relationship between a measurement and the property it relates to
  - domain saref:Measurement and range saref:Property
- saref:represents - A relationship between a service and a function.
  - domain saref:Service and range saref:Function

**Proposal:** To add ObjectPropertyDomain and ObjectPropertyRange axioms wherever the definition of a property unambiguously identifies the domain or the range of a property.

Move the examples to additional resources/documentation and not in the ontology. Only keep Actuator Appliance Sensor Meter, keep HVAC (maybe remove it in the future, add in the comment that there is a link with saref4bldg).  Remove LightingDevice, remove MicroRenewable, remove Multimedia but create an example about Multimedia. remove Network.

Updated the ontology to use hash URIs
