It's "all there is" in the same way that tables and foreign keys are 
"all there is" to relational databases, or that elements and attributes 
are "all there is" to xml.  In practice there will be characteristic 
structures, and relationships and constraints that may be declared in 
(e.g., rdfs or owl) schemas, so there can be all the richness and depth 
you might want.
