We follow the idea of SSN/SOSA and thus reuse a lot of their classes and properties. Therefore, we will only discuss here the other classes and properties.
This is qudt:Unit which we need for Kwantitatieve Waarde.
No existing class found, thus we created a new one.
No existing class found, thus we created a new one.
No existing class found, thus we created a new one.
No existing class found, thus we created a new one. This one was added mostly to illustrate the fact that our data model supports other Erosiebestrijdingsmaatregelen besides Erosiepoel.
This is qudt:Quantity which we use in this track to express the dimensions of an Erosiepoel.
This is similar to SSN/SOSA ObservedProperty but in QUDT. We need this because we use qudt:Quantity. In practice, I think this class and ObservedProperty are actually the same.
This is qudt:QuantityValue which we use in combination with qudt:Quantity for the dimensions of an Erosiepoel. It can also be used a result of an Observatie. This is also mentioned in the alignment between SSN/SOA and QUDT.
This is the "class" for all numerical XSD datatypes. We need it for Kwantitatieve Waarde to say that the value there is a number.
We didn't find an existing class for maintenance, so we created a new one.
There are zones in other OSLO APs and VOCs, but they all have different scopes/definitions. Thus, we create a new one.
