I think the future &quot;may&quot; be the JCR Standard (Java Content Repository), or at least something build &#x27;on top of&#x27; JCR. The only real contender IMO is Apache Jackrabbit Oak. In general what this article describes is a Content Repository, but a real world-wide semantic web has not yet been built with it. My little project meta64.com is a mobile front end for some of this kind of data processing&#x2F;storage.
