Whereas named thing is abstract, attribute value is not abstract. However, doi is the only slot in the NMDC schema with a range of attribute value, rather than a range that is_a attribute value such as text value. I recommend that attribute value be made abstract: true and that the range of doi be made text value or another concretion of attribute value.
