>From time to time, I am changing/cleaning up the &quot;node types&quot; that the repository uses while in development.<br><br>This may mean if you are playing with it you will need to blow away your repo and let it create it (not bothering with migrations as I am still cleaning it up). 
<br><br>I don&#39;t expect there to be many changes once it is finished. JCR lends itself to pretty generic hierarchies, and it is resilient to additions of properties etc. <br><br>As a happy co-incidence. the &quot;CND&quot; format used by Jackrabbit looks like becoming the standard for &quot;JCR2&quot; (JSR-283 I think?) content repos - which means it will be even easier to migrate between different vendors for the database/rules repository.
