DPs with enumerated values are objects in SAREF4BLDG
In SAREF4BLDG, some of the DPs seem to accept enumerated values as objects, but these are only defined in the comment (ex. s4bldg:refrigerantClass) or not defined at all (ex. s4bldg:pipeConnectionEnum). They could therefore be modelled following a common pattern to be decided for the whole SAREF. For example, as an OP with as a range a sub-class of skos:Concept.
Also, some of the DPs (19) have a local name that ends with “type”. This may be considered as a bad naming choice as types are usually modelled as classes in OWL. Some DPs explicit the expected values (ex. s4bldg:circuitType), other do not (ex., s4bldg:integratedLightingType).
