Attributes Tagged Values Advanced Other Links
Attribute | Scope | Type
accuracy | Public | Percentage
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
computationalMethod | Public | ComputationMethodEnum
definition=Method of computation which has been used to compute this data value. order=3 schemaAttribute=yes
dataError | Public | Boolean
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
numberOfIncompleteInputs | Public | NonNegativeInteger
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
numberOfInputValuesUsed | Public | NonNegativeInteger
definition=The number of input values used in the sampling or measurement period to determine the data value. order=5 schemaAttribute=yes
reasonForDataError | Public | MultilingualString
definition=The reason why the value is deemed to be erroneous by the supplier. order=1
smoothingFactor | Public | Float
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
standardDeviation | Public | Float
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
supplierCalculatedDataQuality | Public | Percentage
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.
