Hi Steve,
in addition to Scott's response, please also make sure that both queries
run on the same default graph. Since your query does not include a GRAPH
clause, it will use the currently open model (including owl:imports)
within TBC. In TBL it may use a different graph (unclear how you execute
the query) or may not include the owl:imports and therefore not see the
rdf:value triple.

Hi Folks,
I was debugging a problem I was having with a query, and I think I
have stumbled on a bug in TBL.
Here is a very simple demonstration of something behaving differently
between TBC and TBL:
*SELECT**
*WHERE*{
*OPTIONAL*{
?x rdf:value "dog" .
} .
*BIND* (*IF*(bound(?x), "x is bound!", "x is not bound!") *AS* ?result) .
}
If you run this in TBC, it binds the value “x is not bound!” to
?result, as you might expect, and the value of ?x is unbound.
However, running this on our TBL instance on AWS, you get ?x bound to
“x is not bound!” and ?result is not bound. This is very unexpected.
We’re running version 4.2.1 of TBL, and 4.3.0 of TBC, but I’m
surprised if the behavior of IF changed between 4.2 and 4.3
Any thoughts? Can you reproduce this effect?
