Hi, dear Vladimir Here is what I replyed to Martin (or you see the list ?):
------------------------------------- Well, crm:E78_Collection attracts so much attention either because it is important or it has problems, or both :-) (Second thought: we can say that the guy burying a hoard had a "collection development plan": he planed to "develop", the hoard, retrieving it after some time and spending the coins :-) True that crm:E19_Physical_Object "includes all aggregates of objects", but I feel the need of something like crm:Fx_Assemblage between crm:E19_Physical_Object and E78_Collection, because I would like to make a clear (conceptual) distinction between: <helmet> <crm:Py_is_component_of> <armor> or <coin> < crm:Py_is_component_of > <hoard> and <wheel> <crm:P46i_forms_part_of> <car> So, I would like a crm:Fx_Assemblage exactly for the reason you invoke: „We should only use a more specific class, if we expect the respective additional properties to be relevant for querying.". ------------------------------------- I'm still in doubt... Best, Dan
