| A foreseeable incarnation of Web 3.0 could inherit machine understandability from the Semantic Web, and collaborative editing from Web 2.0 applications. We review the research and development trends which are getting today Web nearer to such an incarnation. We present semantic wikis, microformats, and the so-called "lowercase semantic web": they are the main approaches at closing the technological gap between content authors and Semantic Web technologies. We discuss a too often neglected aspect of the associated technologies, namely how much they adhere to the wiki philosophy of open editing: is there an intrinsic incompatibility between semantic rich content and unconstrained editing? We argue that the answer to this question can be "no", provided that a few yet relevant shortcomings of current Web technologies will be fixed soon. |
