+=head1 OVERVIEW
+
+Authors can only write-access the C</~authorname/> space. They can
+copy resources into the resource area through the publication step,
+and move them back through a recover step. Authors do not have direct
+write-access to their resource space.
+
+During the publication step, several events will be
+triggered. Metadata is gathered, where a wizard manages default
+entries on a hierarchical per-directory base: The wizard imports the
+metadata (including access privileges and royalty information) from
+the most recent published resource in the current directory, and if
+that is not available, from the next directory above, etc. The Network
+keeps all previous versions of a resource and makes them available by
+an explicit version number, which is inserted between the file name
+and extension, for example C<foo.2.html>, while the most recent
+version does not carry a version number (C<foo.html>). Servers
+subscribing to a changed resource are notified that a new version is
+available.
