Treebel is a project that integrates blogging platform functionalities with Semantic Web technology and innovates in the way that Internet users share information. Unlike other blogging platforms, Treebel users can give meaning to the data they post on their blogs, thus getting a rapid improvement in search and notification services used by their readers. Treebel technology not only allows bloggers to semantically organize data and improve the experience of their readers, but it also collaborates with the Semantic Web by sharing information using standard formats.
