Non-deterministic Output Formatting #46

Open Aklakan opened 11 months ago

Aklakan commented 11 months ago

It seems that the output itself is fine, but there seems to be a race condition when configuring the output writer. An alternative reason could be that writer configuration still uses a reflection hack for configuration which might break. Needs investigation.

Running rpt integrate /tmp/data.jsonld spo.rq --out-format turtle gives output with different formatting such as:
