Separation of data, its presentation and functionality

Help needed on XMl and sepratation of data and functionality

[NastyGirlie]

Hi
I am a journalist, now making a research on content management. Made a research on some cms (open source) and read cmswatch, bla-bla-bla. I feel cms must separate data presentation from data itself and it must change both separately. What about website functionality (newslines, navigation...)? The question is: are there any ways to tune functionality like templates which determine onsite data presentation?

Has anyone come across this issue before or can help out, please?

Hi NastyGirlie,

I'm not sure I follow your question.

Seperating data from presentation (and the management of each) is a wide open topic. There are no standards, only suggestions and guidelines.

And for every suggestion and/or guideline, and for every product (OS, free or paid) there are a number of different ways to acheive each.

Or is this your question? Why is there no standard?

XML certainly provides a masterful solution to the above, but it is still just another way to do it.

And yes, seperating the two is ultimately the goal of good web site/application design.

Are you trying to find out more about how XML is used for seperating data and presentation? Or am I missing the boat here?

Hi there. Thanks for your thoughts, very useful indeed :).
I just saw a resource, www.xmlsapiens.org and sapid.sf.net, and found them quite good. They report xml specification and programming core of opensource cms.
