In the realm of Linked Data a de-referencable URI denotes an entity 
(anything) such that *indirection* via de-reference resolves to an 
entity description graph, at an address. Net effect, an application 
focuses its attention on a Data Source Name (DSN i.e., like ODBC and 
JDBC) while having (when the entity isn't of type: Web Document) 
indirect access to an actual data (resource) address.

*indirection* my be implicit or explicit, that's a function of URI style 
i.e., a hash URI gives you *implicit indirection* while a hashless URI 
requires *explicit indirection* by the data publisher e.g., via 303 
redirection.

Basic rules:

1. Web Documents are denoted using via hashless URI/URL (i.e., the 
distinction doesn't matter in this context)
2. Everything else is denoted using a de-referencable URI -- which may 
be hash or hashless .
