Following the result of our recent discussion about the future of Corona, I propose Corona to become Cocoon 3.

This means that any reference on Corona in source files, package names, artifact ids, group ids or anywhere else will be dropped and the standard Cocoon namespace org.apache.cocoon will be used.

This majority vote stays open for 72 hours.

Please cast your votes. Here is my +1

-1

I think it is much too early to proclaim a tiny blossom like Corona to be the heir to the huge thicket called Cocoon. It gives the wrong signal to potential new users and will make them shy away.

They will read it as: "Oh, they are now working on C3.0. So C2.2 will be legacy by the time my project is finished. I may be forced to migrate to 3.0 with lots of incompatibilities. Better I use some other framework for now.

That doesn't make sense. Then this user would have to migrate from the 'other framework' sometime which is most probably more difficult.

I'll have another look when C3.1 is out."

At least that was my personal reaction when in 1999 I first came across Cocoon. I never bothered with C1.7 because C2.0 was already announced as being a complete rewrite. Luckily, I passed by a second time in 2002 when C2.1 was in beta state.

Evolution instead of revolution is the key to success here.

C2.2 almost killed us because it was very bold and then took very long to get out due to the feature creep during the long time it took to get out. Porting stuff forward and backward between C2.1 and C2.2 did and does cost a lot of resources. I would not want to throw in there yet another branch.

There is no need to port things between 2.x and Corona - there is only a very minimal overlap.

Before considering C3.0 we should have finished the C2.1 to C2.2 transition period. And that is not achieved by simply declaring the C2.1 branch to be closed. For that I would like to hear more success stories where people actually migrated non-trivial apps from C2.1 to C2.2.

sure, I'd like to hear them too.

I don't want to stand in the way of progress here. Please carry on with Corona and stay within the Cocoon context but just don't call to Cocoon-x.y.

After 25 days of discussion this was the best solution we found. People were very unhappy with the use of any codename. And meanwhile I think we are all tired of the name finding game.

Cocoon 3 will be announced as alpha software. We will add warning messages to all release artifacts and on the homepage that the code is experimental and contracts can change from patch releases. We will also state clearly that the focus of Cocoon 3 is much smaller (small pipeline API & RESTful webservices) and that, thanks to the servlet-service framework, it can be run very easily in parallel with Cocoon 2.2

Wasn't the original motivation for Corona to have a programmable pipeline container which can be used independently of Cocoon?

The original motivation was that Cocoon 2.x code is one of the most difficult pieces of software that I've ever seen. We tried to refactor it (see 'Micro-Cocoon' in the whiteboard) but found out that this is everything else than simple. While doing this I wondered wow many people do really understand how the environment handling exactly works and can do changes without a long trial and error period?

Maybe stupid question: Why can't it be a set of experimental blocks in trunk which may lateron replace the current sitemap processor?

It's not only the sitemap processor. Corona also has different contracts at pipeline and pipeline component level.
