I am currently on development for the Steinberg Midex8 USB driver.

At the moment I can send notes to my Midi equipment via this device. Receiving is currently not implemented.

My questions are:

1. Are there any tools to test the Alsa-Midi compatiblity ?

You can send raw MIDI data with amidi, or play entire .mid files with aplaymidi.

To see received data, use amidi or aseqdump.

2. May I release some milestone results to the Alsa project ?

Just publish them somewhere.

3. What are the requirements to get released in an official alsa release

package ?

Post the patches against the latest Hg tree here.

4. Where can I read how the source code is organized in the repository

The alsa-kernel tree contains an almost exact copy of the sound/ directory in the Linux kernel tree.

The alsa-driver tree contains the build mechanism for the separate alsa-driver package, patches and compatibility code to make the code in alsa-kernel work with older kernels, and some drivers that are too new or too horrible to allow them into the kernel.

and how to manage tags and branches for the development ?

https://bugtrack.alsa-project.org/wiki/wikka.php?wakka=SourceCodeRepository and see the Hg docs.
