proposed property: void:object

[GoogleCodeExporter]

void:object would identify an object common to all entities in a 
Dataset/subset, just as void:property  identifies a property common to all 
entities in a property partition.

This would allow you to state the number of entities linking to a particular 
entity, or having a particular shared value.
Used in combination with void:property, one could express facets of a 
dataset/result set with VoID.

eg:
[
 void:property dct:date ;
 void:object "1985" ;
 void:entities 354 ;
] .

Is the intention here to express facets over a set of triples (dataset) or over 
a set of resources (entity set)? I ask because I could imagine that one also 
wants to say that all the things described here are of type ex:Movie or 
something.

Yeah facets over entities was the main use case I had in mind. I was imagining 
combinations of facets expressed as nested subsets, like:

<dataset> void:classPartition [  
    void:class bibo:Book ;
    void:entities 500 ;
    void:subset [
        void:property dct:date ;
        void:object "1985" ;
        void:entities 354 ;
        void:subset [
              void:property dct:publisher ;
              void:object ex:Acme_Publishing ;
              void:entities 209 .
        ] ;
    ] ;
  ] ;
.
