Hello,
I managed to establish a connection to my MYSQL database via Jena SDB and
inserted some triples.
However, I still feel insecure how OWL constructs are persisted with Jena.
Here is my Java code example:

I switched from OWL_MEM_MICRO_RULE_INFto OWL_DL_MEM_RULE_INF.

Certainly looks like a bug.
Does this work with 2.7.4?

We can't see your ontology and you don't list the results of your test case.
However, the Jena rule reasoners are (fragments of) OWL full, not OWL
DL. In OWL full then semantically you can state that two literals are
sameas, you just can't directly express it syntactically in RDF. The
