Hi there, Monday I posted the Zope product guidelines to the net. It's here: http://www.zope.org/Members/faassen/product_guidelines Structured text source is here: http://www.zope.org/Members/faassen/product_guidelines_stx Don't cheer yet; this document is *not* complete. In fact, it's a mere skeleton, containing (loosely categorized) my questions. I'd like to see some discussion on the various issues raised in the document on this list. I'd also like to see contributions to the doc. Either more questions, or an attempt at actual answers. Since the answers will set guidelines and standards, it's unlikely an answer will be accepted without at least some discussion by the community. So let's please discuss. For starters, let's try to identify some common tabs in Zope, and their use. For instance: edit tab - use this to edit instance specific data that is not a property. (this is incorrect. The title and other properties can often be edited on the edit tab). How to improve this phrasing? properties tab - you can only use this to display the standard Zope properties screen, here's how: from OFS.PropertyManager import PropertyManager # now include PropertyManager as a base class # now include in manage_options {'label':'Properties', 'action':'manage_propertiesForm'}, proxy tab security tab test tab view tab others? Suggested tab orders? Let's get this discussion going! Regards, Martijn
