Hi Corey, What I can say, with my really limited Zope3 experience, is that this amount of ZCML is comparable to the amount of XML config files needed for Java J2EE development (Enterprise Java Beans, anyone?).
So there's at least one other component-architecture which requires comparable sh**loads of configuration, for even less functionality (or perhaps I should say - different kinds of functionality?). And for J2EE too, all this config-data is really the domain of the app.developers only, not the domain of any admin. And in J2EE, you can really screw up your application by changing as little as 1 line in the config -- I imagine it's gonna be the same in ZCML. And you won't even notice that you screwed up your app until you start testing with more load, more users, and suddenly the output is all wrong and the database corrupt and oops, some developer forgot to set some property here on one EJB bean and the database-access is done in the wrong way and transactions aren't held ... etc... I'm not sure if this is typical for Component Architectures, but it is a trend seen in more places. And it requires you, as developer, to be coding simultanuously in two places: in the code, and in the config. cheers and much luck getting through it, --Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Corey Sent: Thursday, June 23, 2005 8:32 AM To: zope3-users@zope.org Subject: [Zope3-Users] woah... zcml O.D. Appologies if some of these questions seem naive, I'm just beginning to more thoroughly delve into zope3 - of which I've been very impressed so far. However - is it just me, or does zope3 seem to require a rather massive amount of configuration? Is that specifically an artifact of Component Architectures in general? Or is this by design? Are "site administrators" really supposed to understand all that zcml in the configure.zcml files, or are they more realistically the domain of component developers? It seems to me that the configure.zcml looks almost as if it would basically be considered "hands off", once the application/component was coded and installed. Generally how much of any particular configure.zcml could - practically speaking - be modified in a usefull manner? Even for relatively smallish apps, such as the buddydemo and zwiki, the configure.zcml file seem quite large; I hate to imagine what a more involved and complex app would do. Am I just looking at it wrong? Perhaps the basic idea is small amounts of code, and large amounts of configuration/meta-programming via zcml? Many thanks, and again sorry if I'm judging things prematurely based on my limited experience with zope3.
