Goals: right overall spirit?
       is this topic list sufficient?
       are all topics necessary - can we flush some?

.   .   .   Keep metadata close to what it's about.

.   .   .   If "metadata" is actually about variability of a resource,
.   .   .   .   embedded is probably not appropriate, use http: links.
