    rdfs:comment """E4-CIDOC - This class comprises sets of coherent phenomena or cultural manifestations bounded in time and space. It is the social or physical coherence of these phenomena that identify an E4 Period and not the associated spatio-temporal bounds. [...] Typically this class is used to describe prehistoric or historic periods such as the 'Neolithic Period', the 'Ming Dynasty' or the 'McCarthy Era'. There are however no assumptions about the scale of the associated phenomena. In particular all events are seen as synthetic processes consisting of coherent phenomena. Therefore E4 Period is a superclass of E5 Event. [...] Artistic style may be modeled as E4 Period.
++Philosurfical: the subclasses intellectual movement and philosophical movement has been added as types of period.""" ;
