isDefinedBy and isDescribedBy, Tale of two missing predicates

All,

So when all is said an done, post 303 redirection imbroglio, the moral 
of the story *seems* to read as follows:

When you make a hypermedia based Ontology for deployment on an HTTP 
network (intranet, extranet, World Wide Web) do include a relation that 
associates it with the Properties and Classes that it describes. 
Commonly used predicate for this is: rdfs:isDefinedBy [1] .

When you create hypermedia based structured data for deployment on an 
HTTP network (intranet, extranet, World Wide Web) do include a relation 
that associates each Subject/Entity (or Data Item) with its 
container/host document. A suitable predicate for this is: 
wdrs:describedBy [2] .

At the current time, most ontologies deployed on the Web do not include 
rdfs:isDefinedBy triples. The same applies to descriptor documents (RDF 
included) currently deployed on the Web re. wdrs:isDescribeBy.

As a best practice, common use of these predicates would increase 
navigability, link density, and overall cohesiveness of the burgeoning 
Web of Linked Data. It would truly demonstrate practicing what we 
preach, dog-food style!
