I am contemplating to start a project to build a site for storing and serving structured data (animal training plans in my case). I'm a bit overwhelmed by what's available, so I would appreciate any advice and pointers to Zope products and documentation. The format of the data is fairly simple, basically a datum is just a list of items. Since I want my users to be able to download data in a way that preserves structure, I am leaning towards using XML. I don't really need all the fancy features provided by the various Zope XML products, so I'll probably write my own parser in a couple of lines of Python. The partial requirements are as follows: - It should be possible to view training plans in nicely formatted HTML. - It should also be possible to upload and download training plans as raw XML. - It should be possible to browse plans by categories and by full text search. - Training plans should have relationships (e.g. plan X is derived from plan Y) that users can query (e.g. show me all the training plans derived from Z). I have a rough idea of how to do this in Zope, but I would hate to put a lot of effort into it just to discover that there happens to be a product that would make the whole thing trivial. Thanks, Pertti
