Holger,
Thanks for the response. The triple to be matched was really
there in order to NOT have a match, because I wanted to show the different
behavior (between TBL and TBC) when ?x was not bound. Currently trying a workaround using UNION instead, but I'm still bothered by the inconsistent behavior between the two platforms. - Steve Steven R.

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.

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? - Steve Steven R.
