<h3><a name="rms">Reputation Services</a></h3>
<p>
We introduce a set of <i>Reputation Services</i> that form the
cornerstone of the OpenPrivacy framework. These services provide a
- standard reputation framework that can be used by any community,
- supporting an unlimited number of mechanisms to create, use and
- calculate results from accumulated reputation. The implementor of
- these services can nest or reuse existing reputation calculation
- engines or roll their own. They gain the ability to query remote
- RCEs, to perform ontological forwarding, and share all or part of
- their users profile database with other communities without
- violating user privacy.
