Subject [proposal] URI format

Here's my proposal: 

1. The .jars and other artifacts ( docs, wars, etc ) will be distributed
in the same layout and directory structure with the regular Apache 
files, based on the rules for mirroring ( http://... ).
Each project may add a jars/,  wars/ directory next to ( or below ?) bin/.

2. Each jar in the repository will be versioned, with a symbolic link
to the latest released stable version and a symbolic link to the latest 
The "latest stable version" will be referenceable by both the simple jar 
name ( the symbolic link ), and by the full versioned names. Same for the 
latest milestones.

3. The symbolic name should be changed on every incompatible API or major
release. Projects should be able to deal either with full 
versioned names, or at least with major-version names. Example: 
catalina5.jar will be used as the "base names". 
First-version projects or projects where backward compatibility is 
strictly enforced will not have to use a version ( we can keep the 
current names for existing projects ).

Using the mirroring layout:
- the mirror system seems accepted and is already implemented in most
- jars and wars and .sos and other project artifacts are part of the 
release, there is no reason to treat them differently

- it is clear that both verioned and unversioned jars have valid use 
- unversioned jars can be used in projects where the use case applies -
for example if ClassPaths are used in jars or if file-based access id
done for any reason. 
- Using the latest stable version guarantee that upgrades will get the
bug and security fixes and get maximum stability
- Upgrading to the latest milestone will allow people to benefit from
recent features and deal with API changes. ( again - the stable name 
will keep the process predictible )
- It seems this practice is acceptable in maven 
- Versioned jars will be available to satisfy Maven's use case - people
building or running against a fixed version of a particular software.

Major version number in jar names:
- it'll allow people to use/build projects depending on multiple 
- it'll help the use case of tomcat or other containers where multiple
versions may be used at the same time. We still want to use the latest 
minor version out of each major version - for security and bugfix reasons.
- it'll allow people to deal with the API changes
- stable and existing projects can keep the current simple name
