    - a global framework for knowledge, with four fairly unique link resources. You may find this recent blog post (and others?) of relevance?

    There is a communitary effort to create semantic information in small text messages like twiter, jaiku or SMS. Is opened to discussion and all effort is apreciatted. Some apps are using nanoformats to their message syntax. If you are interested: http://www.microformats.org/wiki/twitternanoformats
