1. the author
One or more people who wrote a document.  Their aim is to see their
document available to anyone and translated to as many languages as it's
possibile.  They should commit their work and get back (after a while
;-) the translated versions.  It'd be good if the server would put the
transltaed documents there where the author wants to.

2. the translator
Most probably a team of people whose aim is to translate a document from
one language to another.  They pick up a document from a list of
documents, translate it and commit back to the server.  They need a
person as a coordinator and like to be notified of new document
versions.

3. the reviewer
To assure a good quality of translation, any document should be cheked
by one or more people who speak the language the document has been
translated into.  This avoids the most common mistakes and a more fluid
translation. The reviewer likes to be notified of new translation, too.


In the middle of these three group there are the documents
hosted/managed by a server.

Documents are written as text, plain or formatted (HTML, SGML, LaTeX,
and whatever your immagination suggets).  A document comprises one or
more files, each of which has got one or more authors, one or more
translators per language, and one or more reviewers per language.

The server should be able to provide administration facilities to all
the three actors: user subscription, document subscription, new version
notification, group coordination.
