## ---- Class declarations ----

:ResultSet rdf:type rdfs:Class ;
    rdfs:comment    "Class of things that represent the result set" ;
    .

:ResultSolution rdf:type rdfs:Class ;
    rdfs:comment    "Class of things that represent a row in the result table - one solution to the query" ;
    .

:ResultBinding rdf:type rdfs:Class ;
    rdfs:comment    "Class of things that represent a single (variable, value) pairing" ;
    .

## =======================================
## Modelling style: uses multiple instances of a property
## to represent multiple results.
## e.g. :ResultTable has many :hasSolution properties, one per row

## ---- Properties ----

## - Table level

:solution rdf:type rdf:Property ;
    rdfs:domain     :ResultSet ;
    rdfs:range      :ResultSolution ;
    .


## Useful information extracted
:size rdf:type rdf:Property ;
    rdfs:comment    "Number of rows in the result table" ;
    rdfs:range      xsd:integer ;
    .

## Can be convenient to list the variables beforehand
:resultVariable rdf:type rdf:Property ;
    rdfs:domain     :ResultSet ;
    rdfs:range      xsd:string ;
    rdfs:comment    "Name of a variable used in the result set" ;
    rdfs:comment    "Multivalued" ;
    .


## -- Row level

:binding rdf:type rdf:Property ;
    rdfs:comment    "Multi-occurrence property associating a result solution (row) resource to a single (variable, value) binding " ;
    rdfs:domain     :ResultSolution ;
    rdfs:range      :ResultBinding ;
    .


:index rdf:type rdf:Property ;
    rdfs:comment "Index for ordered result sets" ;
    rdfs:domain	 :ResultSolution ;
    # rdfs:range   ?? ;
    .	
## -- Single binding level

:variable rdf:type rdf:Property ;
    rdfs:comment    "Variable name" ;
    rdfs:domain     :ResultBinding ;
    rdfs:range      rdfs:Literal ;
    .

:value rdf:type rdf:Property ;
    ##rdfs:subPropertyOf rdfs:value ;
    rdfs:comment    "Variable name" ;
    rdfs:domain     :ResultBinding ;
    # Range is anything
    .

## ---- Boolean results

:boolean rdf:type rdf:Property ;
    rdfs:comment    "Boolean result" ;
    rdfs:domain     :ResultBinding ;
    rdfs:domain     xsd:boolean ;
    .
