Scope note

Text

This property associates a kind of object (documented as an instance of E55 Type) with an instance of E4 Period indicating that objects of this kind have been generated exclusively in this period. This property makes a strong statement concerning the distribution of the associated object kind in the observed record: If the genesis of an object of this type can plausibly be assumed to fall within the genesis of the context in which it was found, then the statement made with this property would support reasoning, ceteris paribus, that the genesis period of the find context actually forms part of the related instance of E4 Period, or at least overlaps with it. In contrast, objects from previous periods may appear in a context because they are still in use, and objects from later periods may have been displaced into an older context. Weaker claims can be made using the properties AP29 appears in (gas appearing type) and AP31 typical for (has typical type).
