Associates a CalibrationProcess with its corresponding KCDB service category. Service categories are provided as SKOS concepts distributed across multiple KCDB sub-namespaces, such as: scauv: <https://si-digital-framework.org/kcdb-sc/AUV/>, scem: <https://si-digital-framework.org/kcdb-sc/EM/>, scl: <https://si-digital-framework.org/kcdb-sc/L/>, scm: <https://si-digital-framework.org/kcdb-sc/M/>, scpr: <https://si-digital-framework.org/kcdb-sc/PR/>, sct: <https://si-digital-framework.org/kcdb-sc/T/>, sctf: <https://si-digital-framework.org/kcdb-sc/TF/>, scri: <https://si-digital-framework.org/kcdb-sc/RI/>. Linking a service category to a calibration process allows reasoning about expected measurement results: for example, the `relatedSIQuantity` of the service category can be used to verify whether the units of the result quantity values correspond to the expected SI quantity. Only individuals of rdf:type `sc:ServiceCategory` can be used for this property.
