Correct :)

As for the reader, you might need to implement your own reader for the RAS
descriptor. You can take a look at the different implementations of the
ProjectModelReader which Archiva uses for reading the pom files in the
archiva-repository-layer module for an example. You might also want to take
a look at the ProjectModelToDatabaseConsumer (in archiva-database-consumers)
which invokes the POM reader and adds the POM info to the database.

Uploads via DAV is also supported (see archiva-webdav module) :)

That would be great! Could you create a jira issue for this? We can use that
to keep track of your patches and for reviewing them as well :)
