I checked if maybe we were dropping the binding when creating the ArrayBindingSet, but that doesn't seem to be the case.

Any chance you can create a small dataset that returns results for quantityKind with 4.0.3 but not with 4.1.0-M1?

hmottestad avatar Jul 04 '22 13:07 hmottestad

For the test this dataset was used and worked with 4.0.3, but not with 4.1.0-M1:

maxstolze avatar Jul 04 '22 14:07 maxstolze

I've made a test based on your query and data, but I'm not able to get a binding quantityKind on the main branch or on the develop branch. Could you take a look?

hmottestad avatar Jul 05 '22 04:07 hmottestad

As described the problem seems only to happen with GraphDB. GraphDB 9.11.1 running on RDF4J 3.7.6 and system property org.eclipse.rdf4j.rio.binary.format_version = 1 to be able to use RDF4J 4

maxstolze avatar Jul 06 '22 08:07 maxstolze

Issue still exists with GraphDB 10.0.0 (RDF4J 4.0,2). Tested after MR #4039

Issue still exists with GraphDB 10.0.0 (RDF4J 4.0,2). Tested after MR #4039

Could you help me out with some code so I can try to reproduce this? I'm on holiday for a couple of weeks, but I can take a look again when I'm back.

hmottestad avatar Jul 11 '22 11:07 hmottestad

Sorry for the late reply. We found the problem and it was test data/query based.

There were no quantityKindLabel / unitLabel for the quantityKind / unit provided in the test data. Making the labels OPTIONAL as well, solfed the problem:

...
OPTIONAL { ?f_featureKind mms:quantityKind ?quantityKind ;                          
                          mms:unit ?unit.
OPTIONAL {?quantityKind <http://www.w3.org/2000/01/rdf-schema#label> ?quantityKindLabel .} 
OPTIONAL { ?unit <http://www.w3.org/2000/01/rdf-schema#label> ?unitLabel . } }
...
