Issue 284: Revision of scope note of A3 Stratigraphic Interface
In 33rd meeting the crm - sig decided the scope note of A3 should be revised.
In The 36th joined meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9 and the 29th FRBR - CIDOC CRM Harmonization meeting, the scope note of A3 Stratigraphic Interface is revised. The changes should be incorporated in the new edition of CRMarchaeo , the new scope note is:
A3 Stratigraphic Interface
Subclass of: A8 Stratigraphic Unit
Scope Note: This class comprises instances of A8 Stratigraphic Unit which are coherent parts of a boundary surface, which appear as the result of a stratigraphic genesis event or process. The interface marks the limit of the geometric extent of the effect of a genesis or modification event, and indicates in particular where the effect of this event ended. Each event of creation or destruction of a deposition layer implies the creation of new interfaces. Thus there are two main types of interface: those that are surfaces of strata (that can be directly related to the corresponding stratum via the AP12 confines property), and those that are only surfaces, formed by the removal or destruction of existing stratifications.
The Stratigraphic Interface number  confines the number (2) Stratigraphic Volume Unit, in Figure 5
Properties: AP12 confines (is confined by): A2 Stratigraphic Volume Unit
