Description

On behalf of the Tomas Lindberg from GeologicalSurvey of Sveden:
Reference: Figure 11: UML class diagram of the SOIL relation with O&M classes, and resulting xsd schema

Issue/Summary of discussion: We are using soilDerivedObject to deliver results from geochemical analysis, and the model seems to work fine for this purpose apart from the multiplicity issue described above. We are forced to create a soilDerivedObject for every observation just to add the same geometry for every observed property (we have about 30 elements analysed at the same location), otherwise the schema validation fails. The resulting GML is not efficient and makes it difficult to use in a GIS, where the map is clotted with points at the same location and drawing speed is poor.

We don´t see the point of the restriction to 1, and it is not consistent with the association soilProfileObservation that is 0..*, or the general O&M Extensions to INSPIRE that have a 0..* association between feature of interest and OM_Observation (D2.9 O&M Guidelines Figure 4 Observation Package). We therefore request a change to the model, or in the short term a confirmation if our issue is accepted or if it modeled this way by intention.

Options considered:

To keep the association soilDerivedObjectObservation between SoilDerivedObject and OM_Observation as 1, or to change it to 0..* to allow multiple observations on a soilDerivedObject.

Justification:

The community have agreed this is a reasonable suggestion and that a change to the data specifications would be helpful. Also this change would ensure soilDerivedObject is consistent with soilProfileObservation that is 0..*, and the general O&M Extensions to INSPIRE that have a 0..* association between feature of interest and OM_Observation (D2.9 O&M Guidelines Figure 4 Observation Package)
