I appreciate your point, but Rick's is valid to.

Sometimes it's easy to get the general feeling that people think iBATIS or the ASF is a business, and they expect our project to work for them. 

However, this is not a business.  I don't make any money from iBATIS (as in ZERO).  I've contributed my time for free for over 8 years now.  The framework does what it does.  I do what I can do.   And I prioritize based on what I want to do -- which can be influenced, but not controlled, by the opinions of the community.

It's a hobby for me.  I use my own framework.  The prioritization of what gets done is largely driven by popular community vote, bug criticality and my own needs (as with any other committer who is entitled to prioritize their own features by their own needs -- responsibly).

If there were a way to commercialize it, I would be more than happy to write docs for other people, write specs for other people, implement features for other people, and even make a lot of improvements and enhancements that I know are possible -- for other people.  Unfortunately the practicality of commercialization disappeared the moment I contributed iBATIS to the Apache Software Foundation.

Therefore the best we can do is based on our own time available.

Anyone interested in contributing is welcome to join.  I recommend reading carefully about the Apache Software Foundation first...

Then I recommend you file an ICLA with the Apache Software Foundation -- after you carefully read and understand it.

Then start building your merit through responsible contributions to the framework.

Otherwise, file a Jira ticket, try to get community support and encourage the existing team to support your needs.
