MeasurementSiteTable
The measurementSiteTable (MST) element contains information about the standard configuration and location of measurement sites.
Explanation of measurementSiteTable
Within the Dutch DATEX II version 3 profile, it has been agreed that one MST element is included per provider.
The structure is as follows:
Attributes
| Attribute | Type | Mandatory | Domain | Description |
|---|---|---|---|---|
| id | String | Yes | See explanation | A unique identification of the data provider |
| version | String | Yes | last, See explanation | Constant value indicating the most recent version |
id
The id attribute assigns a name (identification) to the measurementSiteTable. The following has been agreed upon regarding this. The ID starts with a 5-character code. These five characters are assigned by NDW. After these 5 characters, a ‘_’ follows, and then the data provider can append their own identification to form a unique identifier. The following logic is used:
| Data provider type | Prefix |
|---|---|
| geo parcels | GEO01, GEO02, … |
| provinces | PNB01, PNH01, PUT01, PZH01, … |
| municipalities | GUT01, GDH01, … |
| Collaborations | SRE01, … |
| Rijkswaterstaat | RWS01, RWS03, … |
| NDW | NDW01, … |
Subsequent versions of the same measurementSiteTable carry the same id. Therefore, no version number is included in the id attribute.
version
In DATEXII version 3, the concept of Snapshot and AllElementUpdate has been introduced at the MeasurementSiteTablePublication level. As a result, the version number at the MeasurementSiteTable level is no longer relevant. The version number per MeasurementSite is now the leading factor.
Elements
| Element | Type | Mandatory | Domain | Description |
|---|---|---|---|---|
| measurementSite | MeasurementSite | Yes, 1 or more | N/A | The measurementSite element contains information about the standard configuration and location of measurement sites |
