Modelling DeviceCharacteristic including deviceCharacteristicName, dimension, ComputingPower, Mode, PowerSource, velocity

This is an unnecessary intermediate class between the device and its characteristics, and should be deleted.

Proposed change: delete class DeviceCharacteristic.

DP deviceCharacteristicName

DP deviceCharacteristicName "The commercial name of a device."@en

Proposed change: delete and use existing DPs saref:hasModel and saref:hasManufacturer

DP dimension

DP dimension: "The dimension of the device i.e. heightweightlength string."@en

Why weight ? should it be width ?

Proposed change: delete and use SAREF Core pattern for properties : define instances of saref:Property:

s4ehaw:Height a saref:Property
s4ehaw:Weight a saref:Property
s4ehaw:Length a saref:Property
s4ehaw:Width a saref:Property
s4ehaw:Dimensions a saref:Property ; saref:consistsOf s4ehaw:Height, s4ehaw:Width, s4ehaw:Length

ComputingPower

OP hasComputingPower: "A health device characteristic describing the processing power or capabilities of the device (e.g. processor ID and manufacturer, duty cycle, available flash/RM memory, maximum flash/RAM memory...)."
Class ComputingPower: "The computing power capabilities of a Health device."
DP dutyCycle: "The duty cycle for each health device embedded processor, in percent."@en
DP frequency: "The frequency is the number of instructions an embedded processor - within a health device - can perform per second (MIPS)."@en
DP maximumFlash "Indicates the maximum flash memory space (in byte) of a health device."@en
DP maximumRam "Indicates the maximum volatile memory space (in byte) of a health device."@en

Proposed change: delete and use SAREF Core pattern for features, and SAREF Core pattern for properties:

Define instances of saref:Property:

ComputingPower a saref:Property ; isPropertyOf Device ; consistsOf DutyCycle , CPUFrequency , maximumFlash , maximumRam
DutyCycle a saref:Property
CPUFrequency a saref:Property
maximumFlash a saref:Property
maximumRam a saref:Property

Mode

See #1 (closed)

PowerSource

Class PowerSource: "The power sources of a health device, mainly describing energy source and battery related capabilities of the health device (number of power source, source type, rechargeable or not...)."@en
OP hasPowerSource: "A health device characteristic is its power sources, mainly describing energy source and battery related capabilities of the health device (number of power source, source type, rechargeable or not, available power level...)."@en
DP powerSourceType "The type of power source of a health device. It can be solar, battery, electricity..."@en domain PowerSource, range xsd:string
DP rechargeable "This boolean variable indicates if the power source is rechargeable or not, e.g. a rechargeable battery."@en domain PowerSource, range xsd:boolean

Proposed change: Use SAREF Core patterns

SolarPowered a saref:FeatureKind 
BatteryPowered a saref:FeatureKind 
MainsPowered a saref:FeatureKind 
Rechargeable a saref:FeatureKind 
NonRechargeable a saref:FeatureKind 

NumberOfPowerSource a saref:Property
AvailablePowerLevel a saref:Property

Note that Bluetooth has many properties and characterisics to describe the power source or battery status and level. Can we reuse these definitions @guillemin ?

velocity

DP velocity "The velocity of a moving device (in m/s)."@en domain DeviceCharacteristic, range xsd:float.

Proposed change: Use SAREF Core pattern for properties.

Velocity a saref:Property
