OK, here is an example.  This section of Linked Data text from the 
recently-opened EEBO:


is, in my opinion, talking about this non-information object:


How would you model that in the CRM?

This is an aspect of the issue which I don't understand.  If you can't 
(knowingly) decide that you trust an external Linked Data resource and 
are allowed to make assertions which touch on the entities which it 
defines, what hope is there for the whole Linked Data project?  (Or, if 
this constraint is specific to the CRM, then the same point applies more 
locally. :-) )
