I think author (of any creative work) has always been an Organization or 
Person. It is a feature of schema.org that where text is provided 
instead of some expected type, systems consuming the information should 
do their best to interpret that text sensibly. See the conformance 
statement on http://schema.org/docs/datamodel.html.  So, where text is 
found instead of a schema.org Person or Organization type it would be 
natural to interpret that text as the name of a person or organization. 
Much current practice and the examples on schema.org reflect this latitude.
