|E3-CIDOC - This class comprises the state of objects characterized by a certain condition over a time span.
++Philosurfical :It seems that there is a missing slot here. A slot has-state could be used to record the state e.g. in-ruins. It is suggested that such information can be recorded in the has-type slot, however according to the scope note for E1 has-type reflects the class hierarchy. Their solution would also treat the state and the time differently without justification from a modelling perspective. For now, this new slot has been added called has-state which for now has been defined as type string. Later a new class state could be added. As in E53, consists-of is written has-part and falls-within is written as is-a-part-of
