An example taken from the scenario:
{ mappings: { address:address,
name:geoNameCollection.memberGeoName.fullName },
fixedAttributeValues: { featureFunction-1:firefighting,
restriction.securityAttributesGroup_resClassification :U }
}
The developed concept covers currently only simple rules for conflation scenarios, in which all features from the target dataset that do not exist in the source dataset are added
to the result. It can be extended to allow more complex conflation scenarios, e.g. updating of source featuresattributes based on rules.
Figure 20 — PYXIS interface to create and edit conflation rules.
8.2.1.4 Example execute request
The following is an example of a Execute request to execute the conflation process. In it you can see the 3 inputs source, target and rules, and the two elements of the requested
response conflated_result and provenance:

In this execute request, the source and target datasets are specified by WFS HTTP GetFeature requests. Note that a FILTER= parameters is used to only request the fire
stations see Figure 21. The rules are specified in the JSON format described in Subsection 8.2.1.3. As outputs the conflated dataset and the provenance are requested.
