Developing Wikipedia Plus
WikipediaPlus and the Semantic Web
The Semantic Web (web of meaning) is a successor to the WWW (web of text). The basic idea is, rather than having text, which humans process, data is have machine-readable so that computers can process it. Not only should this decrease barriers of human language between users (since computers could assist in translation), but computer-mediated queries could become possible, as opposed to simple text matching, as is still the case on modern search engines. W3C's semantic web language (RDF) associates each 'meaning' with a separate URI (web address).
The wide vocabulary and localisation of Wikipedia make it a natural candidate for a semantic web URIs, and Wikipedia+ is another step towards establishing them de facto as such. Currently, Wikipedia+ is designed for users of the WWW, and it simply issues an HTTP HEAD request to establish the presence or absence of a page with the required name/language combination. In the future, however, operations might not be so limited. For example, it could carry out a semantic query.
XML File Formats
For a definition of the XML file used internally by Wikipedia+, to which it exports a list of sites, see the WP+ XML Schema.
Joint research proposals, interesting ideas and comments all welcome, especially help porting the extension to alternative browsers. Interested parties are invited to get in touch.
