Haystack

The Haystack Project and Piggy are two Semantic Web projects from MIT.

Haystack seems to be some sort of universal information client, working provide a client to objectise information. [Piggy Bank (category)] says it provides via a Firefox extension and a Java server (Bank) a method for collecting, sharing. RDFs are generate via screen scraping.

The Haystack Project is investigating approaches designed to let people manage their information in ways that make the most sense to them. By removing arbitrary application-created barriers, which handle only certain information “types” and relationships as defined by the developer, we aim to let users define their most effective arrangements and connections between views of information. Such personalization of information management will dramatically improve everyone’s ability to find what they need when they need it. We are currently exploring these ideas:

the universal information client - The Haystack client provides everyday [information management (category)] capabilities such as scheduling appointments, reading and creating email, and organizing photo albums. It explores the bringing of information to a single location in order to let users' focus on information instead of programs.

lightweight structured data publishing - Exhibit is a lightweight structured data publishing framework that lets you create web pages with support for sorting, filtering, and rich visualizations by writing only HTML and optionally some CSS and Javascript code.

bookmarks on steroids - The [Piggy Bank (category)] extension is designed to let users of the [Firefox (category)] browser collect and browse "semantic data" linked from ordinary web pages (in the form of RDF).
