Promotion of "Categories" from SAREF4INMA / defining a Pattern for categories ?

OP s4inma:belongsToCategory is very generic and could be promoted to SAREF Core.

SAREF4INMA defines an architectural ODP that derives, for certain entities, a class for batch and categories of these entities. For example s4inma:Item - s4inma:ItemBatch – s4inma:ItemCategory, s4inma:MaterialBatch – s4inma:MaterialCategory, s4inma:ProductionEquipment – s4inma:ProductionEquipmentCategory. OP s4inma:isCategoryOf links the latter element to the underlined element. The notion of Category allows to group and describe similar properties for a uniform collection of objects, thus factorizing their description. This may be generalized to other concepts in SAREF and extensions, such as saref:DeviceCategory, s4bldg:BuildingCategory, etc.

The notion of categories/kind could be useful, for example to link a specific device (the temperature sensor deployed in my office) to its device category (some DHT22).

Or specific Features of Interest (ex. a specific car) to their category (the model of the car)

Proposal adapted from SAREF4INMA: "A category describes a certain kind of features of interest or device (including its model and brand), which is generally static over time. The essential properties of each item in a category are the same. However, small deviations between items might occur, while the essential properties of all items related to a category are similar."
