Hi, Josh Thanks for the insight! I also just noticed that there is a whole lot of good information already up there in the Wiki. This does look like great stuff. I see how it complements Zope's current data storage capabilities. It provides good ways to move XML data in and out of the ZODB via XSLT and to store and manipulate XML data efficiently using XML Documents. These are excellent capabilities indeed. Have a great weekend!

Hi Kevin,
What FourThought/DC are currently doing with Zope will allow for fast transformations to memory-resident structured data( ZDOM or whatever ) to exportable XML documents( which are simply strings of characters ). This introduces( to the Zope world ) cutting edge metaphors in web-application design. All data to be served to a client is some form of XML: including HTML ( a better term: structured data ). The internal structure, or representation( or "deep structure" if you are into Chomsky ), is the data/knowledge as the web site managers see it- and most likely the most accurate and flexible when dealing with the particular
ormation-domain(
this is what theyre paid for :) ). Each user has custom needs- and wants to see this information the way they( or the applications working on thier behalf ) are accustomed to. So, architectually speaking, we need a way to easily and quickly construct XML documents from some meta-type( our internal structure ). This is what ZDOM is accomplishing for us.
Parsing is a expensive endeavor. It is not practical to parse character streams every time we want to get at our data. So the solution is to represent the data as something more computationally digestible. Again : this is what ZDOM is accomplishing for us.
Does this answer your question?
have a good weekend,
Josh Zeidner

Hello,
Thanks for getting this document going. It's good to see where XML is going in Zope.
I do have a question, though. For me, the main value in XML has been in its usefulness as a flexible interchange format. Right now, I can store data as objects (either straight Python or ZClasses) in Zope and transform those into XML if I need to share it with the outside world (eg RSS). Similarly, though I haven't done this, I believe I can take XML from the outside world, parse it and store it in objects in the database. Are there advantages to storing the data in Zope as XML vs. storing my data as objects?
Thanks, Kevin
