Sample data is not an abstract description of the data...it is proper
instance data, in best case in TURTLE syntax.
Sample code is still missing.
Sample output is not telling me that something does not work as expected...
"Not in the oder you want" is no real specification. The query will
order by the URIs of the complexity values. If not it's a bug.
But again, we need sample data, sample, code, which is also know as MWE.
And also the Jena version is interesting for the developers.
