Subject Re: [ApacheDS] Things to consider for big bang refactoring
Date Mon, 01 Oct 2007 16:52:28 GMT
Hi Alex,

some of those items are already in our roadmap :
- OSGi,
- Virtual Attributes,

I suggest that we feed the Roadmap with any other issues. We can then
trigger the roadmap to make it reasonable given the timeframe and
workforce we have.

But essentially, you are right : let's do what we differed for too
long now, this is just the best opportunity.
