FOAF has classes and properties that can be used to relate a person to an online account that they have with a given service.
Many services provide their users with bookmarklets that allow them to interact with their functionality. And increasingly these services are RESTful, meaning the URLs typically include the users account name.
Many people write additional, improved bookmarklets that supplement or extend the basic functionality of these services, sometimes in conjunction with other services. It's often difficult to track all these extra facilities.
Wouldn't it be nice if one could use a browser extension that serves you with all the latest bookmarklets for your services, without your having to track them all down?
Craft an RDF document to describe the bookmarklets.
Output these links as an RSS feed, so that they can be subscribed to using the Firefox Live Bookmark facility. Firefox doesn't allow this, presumably because of potential security breaches
Output these links as a bookmarks file so they can be easily imported into Firefox.
Describing the Bookmarklets
The value of the js:url and js:code properties will obviously need XML escaping.
As a nicety the service should sort the bookmark(let)s by the dc:title of the service name.
