I'm exploring the use of Zope for creating learning environments in higher education. One of the requirements is for a tutor to be able to create a mini site that includes static files along with more active objects like discussion boards. Furthermore they need to be able to make different 'instances' of this site for use by different groups, such that each instance of the site conatins unique instances of any contained active objects (such as a discussion board). The obvious approach would be to just copy and paste the folder containing the master site, but there are a couple of problems with that: (1) changes to the master site will only be reflected in new instances of the site, and (2) a lot of static files could be getting copied each time. What I think I need to do is to develop a facility that makes a tutor's site into a product. Instantiating such a generated product should make a smart clone of the master site, smart in the sense that only active objects are actually cloned, but static files are shared among all instances of the site. I suspect that ZClasses might be involved to achieve this, but are there any issues with the fact that a master site could contain folders? Furthermore I'd like a tutor to be able to visit their productised site to update it, without seeing a lot of alien stuff; changes to the master site should be reflected in all instances of the site. Am I on the right lines here? Any pointers would be appreciated. Hamish Lawson University of St Andrews, Scotland ____________________________________________________________ Do You Yahoo!?
