Attribute
Public Percentage
  accuracy
Details:
definition=The extent to which the value is expected to be free from error, measured as a percentage of the data value. 100% means fully accurate.
order=2
schemaAttribute=yes
 
Public ComputationMethodEnum
  computationalMethod
Details:
definition=Method of computation which has been used to compute this data value.
order=3
schemaAttribute=yes
 
Public Boolean
  dataError
Details:
definition=Indication of whether the value is deemed to be erroneous by the supplier (true = erroneous). If not present, the data value is assumed to be ok. This may be used when automatic fault detection information relating to sensors is available.
order=0
 
Public NonNegativeInteger
  numberOfIncompleteInputs
Details:
definition=The number of inputs detected but not completed during the sampling or measurement period; e.g. vehicles detected entering but not exiting the detection zone.
order=4
schemaAttribute=yes
 
Public NonNegativeInteger
  numberOfInputValuesUsed
Details:
definition=The number of input values used in the sampling or measurement period to determine the data value.
order=5
schemaAttribute=yes
 
Public MultilingualString
  reasonForDataError
Details:
definition=The reason why the value is deemed to be erroneous by the supplier.
order=1
 
Public Float
  smoothingFactor
Details:
definition=Coefficient required when a moving average is computed to give specific weights to the former average and the new data. A typical formula is, F being the smoothing factor: New average = (old average) F + (new data) (1 - F).
order=6
schemaAttribute=yes
 
Public Float
  standardDeviation
Details:
definition=The standard deviation of the sample of input values from which this value was derived, measured in the units of the data value.
order=7
schemaAttribute=yes
 
Public Percentage
  supplierCalculatedDataQuality
Details:
definition=A measure of data quality assigned to the value by the supplier. 100% equates to ideal/perfect quality. The method of calculation is supplier specific and needs to be agreed between supplier and client.
order=8
schemaAttribute=yes
 
Tag Value
definition A data value of something that can be measured or calculated. Any provided meta-data values specified in the attributes override any specified generic characteristics such as defined for a specific measurement in the MeasurementSiteTable.
