The point metadata applies to an individual point. Although default values may be set depending on the encoding. In the XML encoding in this specification the concept of default point metadata is implemented.
Attribute
Public DataQualityCode
  quality
Details:
Notes: This property is for specifying a quality assertion using the Timeseries Profile defined concepts of quality as described in the DataQualityCode list. When a non-standard quality code is required a SWE Qualifier property shall be used.
Public NilReason
  nilReason
Details:
Notes: This property describes the reason that a point has been identified as null. This provides context for interpreting null points (e.g. missing, withheld etc.).
Public CharacterString
  comment
Details:
Notes: Context information that does not fit into a controlled list of qualifiers, processing or quality information is often provided in free text per point. The comment property provides a placeholder for such textual information.
Public OM_Observation
  relatedObservation
Details:
Notes: This property allows individual points to be associated with related observations. This is used when a timeseries consists of interleaved observations from different sources and understanding the relationship to existing observation(s) is important.
Public Quality
  qualifier
Details:
Notes: The qualifier property is used for qualifying information that is broader in nature than the quality property. These often include indicators or flags that provide further context for the value.#lt;br /#gt;#lt;/p#gt;#lt;p#gt;Quality information often aggregates these elements, but qualifiers allow for deeper interpretation and capture of useful information on a per point basis. The qualifier uses the SWE Common ‘Quality’ union that allows a qualifier to be specified using a Quantity, Quantity Range, Category or Text type.#lt;br /#gt;#lt;/p#gt;#lt;p#gt;The qualifier type may also be used to specify a quality code where the Timeseries Profile quality codes are not being used or where an internal quality code needs to be preserved with the data. #lt;br /#gt;#lt;/p#gt;
Public ProcessingCode
  processing
Details:
Notes: The processing property allows for the categorisation of the processing that has been performed on the time series. This is closely related to the procedure information as defined at the observation level, but allows for more granular definition (i.e. on a per point basis). Often a default processing type will be set for a whole time series, such as a for a forecast time series. The XML encoding handles these cases with a defaulting mechanism.
Public MD_DataIdentification
  source
Details:
Notes: This property allows for granular definition of the source of a particular timeseries value. The property points to an object of MD_DataIdentification type (from ISO19115) that provides context on where the data was sourced. This is useful derived time series where the values are aggregated from multiple sources. The property is by reference only meaning that the full MD_DataIdentification type would not be encoded directly but referenced. The XML implementation provides a means to do this.
