* Module Outline *
This module collects RDF/RSS/ATOM feeds from the registered sites, and stores in a database.
This module searchs feeds in database, and carries out the search results in RDF/RSS/ATOM form.

This module becomes independent from the RDF/RSS/ATOM function of WebLinks module,
and enhances more powerful.

This module aims the platform of RDF/RSS/ATOM feeds.
As an example of application, like a headline module, like the Web Service http://sf.livedoor.com/.

Now, it is the beta version.
From now on, the specification and implementation may change sharply.
Even if some problems come out, only those who can do somehow personally need to use.
Welcome the proposal of specification or the example of application, a bug report, a bug solution, and your hack, etc.

Demo is here
