[jira] [Comment Edited] (JENA-1966) The base URI of a jsonLD file
doesn't appear to be swapped out correctly. The first "./" is replaced
correctly with the specified base, but after that, blank nodes that don't
end up in the final graph seem to be created.

Workaround: Include a URI "http://demo.com/"
Apache Jena uses [https://github.com/jsonld-java/jsonld-java] for JSON-LD processing.
[https://github.com/jsonld-java/jsonld-java/pull/280]
Jena 3.16.0 uses jsonld-java 0.12.5. Upgrading to the latest jsonld-java should include their fix.
Jena 3.16.0 was released 2020-07-09. The fix is in jsonld-java 0.13.1 which was released 2020-09-09.
