Hi Jeremy, will need to double check with my coworkers when I get in the
office on the version (we are licensed users).  Nevertheless, we wouldn't
want to be version locked. For us, we have two classes of users. Advance
(modellers) and casual (subject matter experts and product owners). We find
that tb is too complex for the casual users so are developing a simple web
interface for them to interact with the models in a very controlled way.
With that, a 3store makes sense and so if tb can also use the 3store, we
could greatly simplify our approach.
