I think you are looking for tooling really. Maybe something along the lines of
http://jsr170tools.day.com/crx/nodetypes/index.jsp might help you.

Well, it is a requirement developers have an understanding of
the API that they are using. Now, if you get that knowledge through
going through a training, by reading a book (which does not
exist for JCR yet) or by reading the spec is up to you.

I think it is to be expected that the number of educational options
are more limited for new technologies, but will grow over time.
The reason why is mention the spec is because it is available
from the very beginning.

...and I am not saying that it is perfect. I guess that's the beauty of
a community open source project. As Jukka put it: Contributions
(also to the documentation and the website) are always welcome.

I think this is a very interesting statement and I think it might
have something to do with the fact that you usually start to work
with technologies relatively late in their evolutionary stages,
when tooling and tutorials already exist to their full extent.

Early on in the process, there is nothing but the spec. Tools and
tutorials always come later. I am thrilled to see that Jackrabbit and
JCR continues to evolve and attracts more than "just early adopters".

I think we are in agreement that tutorial style documentation and
tooling is very important to the growth JCR and Jackrabbit to become

We are working on a JCR book but the more the merrier. Feel free to
make your voice heard to the "publishers" ;)

I think that's a great quote. It really stresses the "intrastructure" direction
that JCR should be taking.

Work in progress though, but it may show to you that we are on the
same page, it is just about timing, I guess.
