Hi, I noticed http://viewerjs.org/ which seems to be tied in with the WebODF project (correct me if I'm talking to the wrong people) and I wanted to share a similar project that I and others have been working on as part of the Resilience research project. Perhaps we can collaborate. WebViewers is similar to viewerjs.org except that we concentrated on standardizing the format of a WebViewer so that they can be interchangeably plugged into any supported web application and the application's WebViewers subsystem will automatically begin displaying edit/view buttons in the user interface depending on the viewers which are available. The WebViewers protocol should be well described on http://webviewers.org and if anyone has any questions or if anything is omitted, please do let me know. Also any opinions about what is desirable or might be missing are most welcome. Thanks, Caleb
