CambridgeSemanticWebGatherings

January 22, 2007 - Cambridge - Massachusetts - USA map it


Official Website


Tim Berners Lee sent an invitation to chat about the SemanticWeb at MIT in Cambridge, MA USA on 22 Jan 2007. The idea is to get together people in the local area who are interested in and/or working in the Semantic Web. A typical form will be a few presentations of recent work or recent problems discovered, some moderated discussion in the round, and a large amount of unmoderated chat.

A couple of demos

At the meeting two demos have been presented :

Regarding the second demo, Ben Adida is chair of the RDF in XHTML Taskforce. He presented a demo based on RDFa Bookmarklets. These can be used simply by dragging them on the bookmarks bar. Then, if you want to process RDFa metadata embedded in a page, you open the page and you click the bookmarklet. In the case of the Live Clipboard, some icons will appeare in correspondence with metadata. It is possible with the standard copy comand to copy such metadata (clikking copy on the icon) and to paste them in the Live Clipboard that displays them.

Cliking on one of the orange icons anc pressing the standard copy button, the RDFa metadata will be copied in the clipboard and it will be possible to paste them in the orange icon in the first demo page (figure 1). You will obtain the representation of such metadata as above for instance.

In the same way, taking a page from the first demo MultimediaN E-Culture Project and for instance the page. We are able to copy the metadata related to the painting.
