Hi, As part of a other application we need a tagging component. However instead of just duplicating the ''known'' social bookmarking tool we want to extend the way people tag there pages. Let me explain by giving you an example: "When I like a book on Amazon, and I tag the link, I want the application to ''fetch'' as much information as the Amazon (or other web 2.0 api''s) can give me to include this. So amazon could provide me with the best title to use (instead of using the page title), tags, rating, licence of content, enc. I could just display a simple title, description, tag in the list but on mouseover a diaglog could apear with the ''extra'' information amazon provides me" So what we are searching for: * A initiative (or standard) that provides a standard way of letting applications tag there content (I looked at microformat enc, but could find something). * A way to add connectors to a rails application thru a web interface without risking hacking attempts It will be a MIT licenced rails engine using http://rails-engines.org/... Thnx, Abdul
