I am assuming this project is effectively dead as there doesn't appear to have been any recent activity! Perhaps things could be started up again by employing PHP/Apache/MySQL and developing a system based on the principles of Content Management Systems (CMS). This would require, in the first instance, setting up the core functionality (database connectivity, user administration, security etc) of a system that could be expanded by the development and subsequent istallation of various modules to deal with specific areas of scientific endeavour. Any thoughts? Anyone?
