describe not working with reasoning

[Håvard Ottestad]

Hi,

I'm on the latest version of the community edition, and I'm having some troubles with describe queries.

When I disable reasoning, the describe query returns a graph of the resource, but when I enable reasoning it returns nothing. Even if there is no Tbox.

My query is like this: "describe <http://example.org/resource1>"

Select queries are fine and return the expected results with or without reasoning.

Thanks,

Håvard

This is the expected result. We plan on extending describe to support
reasoning in the future, the ticket number is #2104. In the meantime,
you should just write a construct query that performs the reasoning
you want.

To clarify, did you mean that you're not getting the inferred results,
or you're not getting *any* results. Describe should work the same,
with or without reasoning.

I'm not getting any results when I use reasoning.

But this is better than getting a wrong result. However an exception in the sesame stack would be even better. Something along the lines of UnsupportedOperation would be super helpful.

I've implemented the query with construct, and it works as expected.

Thank you for replying so quickly.
