Note, that doc complete ignores the fact that RDBMS engines have offered 
TableSpaces [1] for eons. The concept of "Data Spaces" (like many 
contemporary DBMS technology efforts) is about decoupling in such a way 
that's RDBMS engine agnostic. Same applies to Views, Triggers, Tables 
(Relations) etc..

RDF, SPARQL, so called RDF stores etc.. are ultimately contributions to 
the intensional DBMS dimension (where relational property graphs are 
strong) that's been overlooked for years.

Deductive database [2] systems tried to tackle these issues with little 
success at a time when we didn't have Internet and Web ubiquity. Thus, 
most failed. Same applies to OODBMS and ORDBMS efforts. These failures 
don't render the work (and associated terminology) from these realms 
useless, hence my eternal tendency to encourage alignment re., terminology.

An RDF data source is a natural compliment to a SQL, ODBC, JDBC etc. 
data source. But, you get better qualification when you as "name" .

ODBC data source names originate from X.500 names.
