Hello Steve,

the use of rdf:resource.

best wishes,

In CM, these links are resources and can be deleted.  They are just quite 
light weight, the are resources that only have properties such as a label 
and a URL to the resource they represent.  We didn't expand on the 
construct as it followed typical REST semantics.  We introduced the 
collref attribute to identify URL that represent a collection of 
resources, so consumers will know that collection semantics apply: knowing 
that GET'ing the URL from collref will result in a feed/collection of 
resources.  Then those resources can be GET, PUT, DELETE, etc.
