| Mapping |
This class expresses an RDB and RDF mapping.
|
| MappingUnion |
A union of mappings.

| RestrictedExpr |
[SPARQL level]
A restrictedExpr is comprised of
- An SPARQL expression
- restrictions associated with its corresponding value after evaluation (under some interpretation)
Example:
Some expression can be declared to yield integers in the range [0..4]
or uris with certain prefixes.

| VarDefinition |
A variable definition binds a set of SPARQL variables to a
set of corresponding defining expressions
A variable definition consists of a
- a restricted expression that defines the variable
- an optional set of restriction expressions that restricts the variables set of values //apply to the variable under this definition
The expression can either be:
- a constant NodeValue that directly associates the variable with a constant
- an expression of type E_RdfTermCtor,
- other expression types probably do not make sense here - at least I don't see use cases for them (yet).

| VarReference |
TODO This is a syntactic construct that gets translated into something different (i think)
|
| ViewDefinition |
A view definition is comprised of
- A name
- A template (a set of quad patterns)
- A mapping
- A set of references to variables declared in other view definitions.
|
| ViewReference |
A reference to another view definition's logical table.
