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 ;
] .
