## A module is a binding (association between thing and this instance)
## and a class (code) that provides the functionality of the module.

:Module a rdfs:Class .

:ModuleBinding a rdfs:Class .

# Typical use for this property is to use (or subProperty)
# to associate the resource with the binding described.

:module a rdf:Property ;
#    rdfs:domain    rdfs:Resource ;
    rdfs:range      :ModuleBinding ;
    rdfs:comment    "Module binding" ;

## Binding


:interface a rdf:Property ;
    rdfs:domain     :ModuleBinding ;
    #rdfs:range      rdfs:Resource ;
    rdfs:comment    "URI of the interface for the binding." ;
    .

:implementation a rdf:Property ;
    rdfs:domain     :ModuleBinding ;
    rdfs:range      :Module ;
    rdfs:comment    "Identifies the implementation to use" ;

## Provider/Implementation

:className
    a rdf:Property ;
    rdfs:domain   :ModuleBinding ;
    rdfs:range    rdfs:Literal ;    # Class name as string
    rdfs:comment  "Load Java class"
    .

## # Example.
## # The general structure is
## # thing
## #   module:module
## #     module:implementation
## #
## # Note the inclusion of argument to the class and instance in a 
## # vocabulary defined by the interface designed and implementation provider.
## # Often these two roles are the same so the namespaces will be the same.
