How does Wiccle work with data? In EE you publish data, then use templates to grab the data you want. MODx has you creating pages directly and makes it a bit more painful to get data from a blog appearing on your main index page etc.

And are things like "custom form fields" possible? Instead of having [Title] and [Body] for a page can we have something like this:

While most of the below applies for the current iWiccle 1.11 as well, I'm commenting Wiccle Web Builder (as to be launched -- and in the next version of iWiccle).

There is of course a complete separation of data, languages and templates in the system. You can either run the site in real time, or use an intelligent multi-level cache system that helps you optimize the serving out of complex data-language-template combos.

There are quite a few database metadata fields for "post-level content" (ie. blog posts, photos, store products, articles, etc.), not all of which are in simultaneous use in most modules, and that can be re-employed for different metadata purposes with simple template changes.

The Infobase module offers a builder tool that lets you create custom field structures to extend your data, and there's also a way to build in essentially infinite extensions to form input and subsequent display with easy-to-do form-data post-processor extensions.

Bottom line, our system is easy to extend, modify, and morph into just about anything. Let's start off with that. =)
