Motion to update the definition and comments of .biologicalSource in Device, NutritionProduct, and BiologicallyDerivedProduct to: Name: biologicalSourceEvent Short Name: An identifier that supports traceability to the event during which material in this product from one or more biological entities was obtained or pooled. Definition: An identifier that supports traceability to the event during which material in this product from one or more biological entities was obtained or pooled. Comments: Necessary to support mandatory requirements for traceability from donor/source to recipient and vice versa, while also satisfying donor anonymity requirements. The element is defined consistently across BiologicallyDerivedProduct, NutritionProduct, and Device.  The identifier references an event that links to a single biological entity such as a blood donor, or to multiple biological entities (e.g. when the product is an embryo or a pooled platelet product).  A single biologicalSourceEvent identifier may appear on multiple products of many types derived from a single donation event or source extraction.  As an example, a single donation event may provide 2 kidneys and a liver for organ transplantation, 2 corneas for eye surgery, heart valves and arterial tissue for cardiovascular surgery, multiple skin grafts, tendons, multiple shaped bone grafts and a large number of bone putty/paste products; and each of them may be assigned to the same biological source event identifier.
