Hi everyone,
my name is Alessio Stalla, I work for ManyDesigns s.r.l. and I am a member of the local Java User Group in my city, Genova (Italy).
My company has been developing a new version of our open source, high level model-driven framework to build database-backed Java web applications, called ManyDesigns Portofino, which is going to be released to the public soon. This brand new 4.x version uses Liquibase to get a snapshot of the database schema(s) you are connecting to, in order to initially create a model reflecting the database, or to update an existing model with changes from the database. A model builds upon the physical structure of one or more db schemas, adding logical annotations and other high-level properties.
Additionally, Liquibase is exposed to users that want to track changes to their DB with it. Every time Portofino starts and when instructed to do so, it executes a Liquibase changelog file against the database.
We used Liquibase by leveraging its API rather than accessing it from the command line like the majority of users. We also wrote a few of our own database abstractions on top of the built-in ones. I think we can be considered advanced users 
We believe that both us and the Liquibase community can benefit from mutual cooperation. We would like to offer Liquibase users the opportunity to download a preview of our framework, to gather impressions and ideas for improvements, as well as criticism. We have set up a page on our site for that purpose: <http://www.manydesigns.com/en/portofino/portofino4>. If you’re interested, give it a shot and have fun!
Alessio
