The application I am developing is for a musician who currently has an Excel sheet with more than 20.000 pieces of old music (1600-1900) where each PieceOfMusic object refers to other objects like Composer, OrchestralSetting, Instrument, Cast, Recording, Writer, etc. Those need to become different kinds of Python objects that the PieceOfMusic object can refer to in order to guarantee consistency. I have designed an object model with all the classes, their attributes and relations in a UML diagram, but now I need to convert the Excel sheet into Python objects in Zope and make them accessible through ZPT pages and Python methods based on this UML model.
This sounds like it might be an equally good (or possibly better...) fit for an RDBMS solution. Is there a reason why this is not an option for you? -- Regards, PhilK Email: phil@xfr.co.uk / Voicemail & Facsimile: 07092 070518 "the symbols of the divine show up in our world initially at the trash stratum."
