Open KathiSchleidt opened 10 months ago

@rob-metalinkage An example, to see if we can align SOSA and STA

Taken from the air quality STA at https://airquality-frost.k8s.ilt-dmz.iosb.fraunhofer.de/v1.1 The @iot.selfLink will resolve to the shown JSON

SensorThingsAPI_DatenModel_v1 1-900

From: https://datacoveeu.github.io/API4INSPIRE/sensorthingsapi/requestingData/STA-Data-Model.html

nmtoken commented 10 months ago

Is a feature really metadata, as in:

"metadata": "http://luft.umweltbundesamt.at/inspire/wfs?service=WFS&version=2.0.0&request=GetFeature&typeName=aqd:AQD_SamplingPointProcess"

Perhaps it should point to a description of the feature like:

"metadata": "http://luft.umweltbundesamt.at/inspire/wfs?service=WFS&version=2.0.0&request=DescribeFeatureType&typeName=aqd:AQD_SamplingPointProcess"
KathiSchleidt commented 10 months ago

@nmtoken this data is originally provided via SOS as part of the Austrian Air Quality Reporting. Within API4INSPIRE, we harvest this and re-provide as STA, keeping the original values.

Not sure why I didn't link to DescribeFeatureType when I set up the original SOS ages ago, probably because the DescribeFeatureType response is strangely unsatisfying:

<xsd:schema elementFormDefault="qualified" targetNamespace="http://dd.eionet.europa.eu/schemaset/id2011850eu-1.0">
    <xsd:include schemaLocation="http://dd.eionet.europa.eu/schemas/id2011850eu-1.0/AirQualityReporting.xsd"/>
</xsd:schema>

Goal here is to see how STA aligns with O&M/OMS
