It doesn't matter if modules are loaded via the 'artifact' tag or the
'directory' tag.

Configuration is retrieved from the ConfigurationManager using a group
and name, the path attribute in the myconfig.xml has as value
"group/name".

So it really depends on what you do in your plugin.

Assuming you're retrieving the configuration in spring, and have
something like this in your plugin's applicationContext.xml:
      <conf:configuration group="mystuff" name="myplugin"
source="configurationManager">
then the path attribute would have as value "mystuff/myplugin".


If you look in Daisy's source, you will see e.g. the following for the
LDAP module:
  <conf:configuration group="extra" name="ldap-auth"
source="configurationManager">

but in the myconfig.xml you'll see 
  <target path="/daisy/repository/authentication/ldap">

Following my previous explanation you would think it should be
"extra/ldap-auth". Well, this will actually work. The other path value
is for backwards compatibility with older Daisy installations. If you
grep the Daisy source code for this string, you'll find the mapping
table between the old and new paths.
