Hello Pim; That kind of behavior is expected only when ?id is not
bound to a value. For example,the following query:
SELECT ?object
WHERE {
LET (?id := smf:generateUUID())
LET (?object := smf:buildURI ("http://www.bimtoolset.org/
ontologies/BB_coins.owl#_{?id}")).
}
Results in a binding for ?object such as:
<http://www.bimtoolset.org/ontologies/
BB_coins.owl#_6cbe8818-2990-11b2-803a-d324a8b08df7>
Can you check and make sure that ?id is bound to a non-null value? If
not, what version of Composer are you using and what OS/architecture?
