>             Project: Rya

> The Fluo PCJ Updater application currently only allows you to add new statements to generated PCJs. We would also like to be able to delete statements from the end results.
> Here is a simple example to illustrate the point. Suppose you are computing the following SPARQL query as a PCJ:
> {code}
> SELECT * 
> WHERE {
>     ?person <http://worksAt> <http://CoffeeShop> .
> }
> {code}
> And you insert the following Statements:
> {code}
> {
>     [<http://Alice>, <http://worksAt>, <http://CoffeeShop>],
>     [<http://Bob>, <http://worksAt>, <http://CoffeeShop>],
>     [<http://Charlie>, <http://worksAt>, <http://CoffeeShop>]
> }
> {code}
> The PCJ will result in the following binding sets:
> {code}
> {
>     [<http://Alice>], 
>     [<http://Bob>], 
>     [<http://Charlie>]
> }
> {code}
> We should also be able to delete the following statement:
> {code}
> [<http://Bob>, <http://worksAt>, <http://CoffeeShop>]
> {code}
> And the PCJ should be updated to contain the following results:
> {code}
> {
>     [<http://Alice>], 
>     [<http://Charlie>]
> }
> {code}
