Cindy,
We do not recommend SDB for new uses. We recognize that in some
situations, the use of existing SQL databases is a requirement; we also
recognize that "data is sticky" - it's not so easy to migrate from
existing uses to newer ones.
We do no recommend SDB for new uses; we recommand TDB. However, we are
not removing the SDB codebase; indeed, by integrating it into the main
build, we ensure it tracks changes.
We would be delighted if new people would come along and contrinbute to it.

Are there any other Jena frameworks that might support MySQL?

I'll check with our DB guys, but this is the list of jars they gave
us. Oracle has its own implementation of the Jena adapter; we'd like
to benchmark it against SDB using the same jars as they built with.
2.7.3 less than 2 months after 2.7.2 (bug fixes).
Odd benchmark though - SDB is deprecated!

Which version if jena-sdb goes with these jars:
<include name="jena-core-2.7.2.jar"/>

Must it be these versions?
You can see the Apache Jena SDB versions and check their versions by
looking in the POM files:
http://central.maven.org/maven2/org/apache/jena/jena-sdb/
SDB 1.3.5 is
<ver.jena>2.7.3</ver.jena>
<ver.arq>2.9.3</ver.arq>
SDB 1.3.6 is
<ver.jena>2.10.1</ver.jena>
<ver.arq>${ver.jena}</ver.arq>
They are the only releases from Apache.
1.3.5 (Jena 2.7.3 is 3-Aug-2012) might work with 2.7.2 (28-Jun-2012)
with only a few tweaks but upgrading would be better.
