The successful harmonization of the ABC Harmony for Digital Libraries and the CIDOC CRM created some minor proposals for the CRM to widen definitions of some properties.
P12 occurred in the presence of (was present at) should have range E77 Persistent Item, in order to include Actors and other things. Non-material objects, like texts, ideas, plans, names, are understood to be present via some physical carrier or a Person having knowledge of it, Groups via some representative. Physical Stuff is understood to be present in the place of the Event.
This solves the conflict, that Groups may participate in an Event but not be present. It clarifies, that non-material items can be present at more than one place at the same time, but not be present everywhere at the same time.
