At this point a common set of metadata like DC can help to improve search engines to more intelligent agents. It is not the idea of DC to have a hand full of experts, who know how to produce metadata, but to let the authors produce meta-information. Nobody else will ever know the document as good as the author himself. Consequently, tools have to be developed, which allow authors to markup the documents with correct and complete DC-meta tags without the author to become an expert of DC before. Of course the production of metadata is work in itself, but as experienced in physics it can raise the potential of the documents.
Metadata become a new kind of value of a document.
The tools for metadata production have to be easy to use. This means, that they have to be intuitive and usable without any specific installations on the computer. WUFI will guide the author to produce metadata and also will upload the document onto the WWW server. Thus, the author doesn't have to know any extra passwords for the WWW server or need to know how to use FTP etc. So the author needn't to install any extra software nor have to run any Java applets on his computer.
