This analysis is right on. Does this demonstrate a hierarchy of natures similar to a type hierarchy? Such a hierarchy of natures is distinct from a classic type hierarchy as it cuts across types incorporating content-types, document types and (perhaps in another example schema types). Yet this heirarchy is not obvious from examining the URIs themselves and so we need a way to express its definition. Perhaps in english as: resources which have a nature of http://www.w3.org/TR/html4/ are defined to inherit the nature of http://www.isi.edu/in-notes/iana/assignments/media-types/text/html and perhaps in RDDL as: <rddl:resource xml:base="http://www.w3.org/TR/html4/" xl:arcrole="http://www.rddl.org/purposes#definition" xl:role="http://www.rddl.org/natures#nature" xl:href="http://www.isi.edu/in-notes/iana/assignments/media-types/text/html" ><p>Resources which have a specific nature of HTML 4.0 i.e. http://www.w3.org/TR/html4/ have a more general nature of text/html i.e. http://www.isi.edu/in-notes/iana/assignments/media-types/text/html </p> </rddl:resource> -Jonathan
