https://register.admin.ch/sfa/lottogewinnepython what is missing is path to observation

https://energy.ld.admin.ch/sfoe/bfe_ogd84_einmalverguetung_fuer_photovoltaikanlagen/2/observation/

Dimension needs path. Path is the predicate. sh:path.

sh:path is the connex from shape to observation-dimension.

example: https://energy.ld.admin.ch/sfoe/bfe_ogd84_einmalverguetung_fuer_photovoltaikanlagen/2/shape/

the sh:path for observation year is https://energy.ld.admin.ch/sfoe/bfe_ogd84_einmalverguetung_fuer_photovoltaikanlagen/Jahr
