> We can't use Sail to maintain PCJs because it does not support visibility maintenance. If we want to do batch PCJ maintenance through the shell, we will have to implement it in a visibility compatible way. Right now, all derivative binding sets have no visibilities associated with them.
> For example, suppose you load the following statements:
> urn:alice, urn:talksTo, urn:bob vis: a
> urn:bob, urn:worksAt, urn:tacoJoint vis: b
> If you are computing the following SPARQL query as a PCJ:
> SELECT * WHERE {
>     ?person urn:talksTo ?employee .
>     ?employee urn:worksAt ?employer .
> }
> Then you will get a Binding Set in the PCJ for that query with no visibilities instead of "a&b".
