I have some documentation that I created when creating our Mylyn
connector here. It's not complete (our connector only has read only
access to the repository), but it's much closer to a step-by-step guide
than a description of one of the APIs. That is, instead of trying to
explain the different APIs, it's more of a cook book for how to write a
connector. I wrote it for Mylyn 2.3, but I updated it for Mylyn 3.0 as
well as i could.
That's great! A connector howto would be a valuable addition to the integrators reference.
I thought that it would make sense to create a new major section on
http://wiki.eclipse.org/index.php/Mylyn/Integrator_Reference, but I
can't figure out how to do that. If you can point to where/how you want
this content, I'd be happy to put it up on the wiki.
Once you login to the wiki, you can use the Edit link on the top left to edit the entire page. Feel free to add your content to the integrator reference where you feel it fits best or create a new page and link to it.
