Track: Understand XWiki core concepts

= Task 3: Understand XWiki concepts = AWM has made it simple to create your first application but it's cheating a bit since it's doing all the work of generating the various wiki pages for you.

:) To do that you need to understand the concepts of XClass, XObjects, XProperties, Sheets and Templates.

XWiki is quite a foreign concept to many people. e.g. people who are not in the tech world; Grandpa/Grandma old generation.

Example to illustrate formentioned concepts. Ex: Ajax request to add and init an object

Is there any documentation on that? Where do these concepts belong to in the first place, Struts, XWiki, Velocity or another technology?

Example to illustrate formentioned concepts. Ex: Ajax request to add and init an object

I actually could use the concept. 13:46 <vmassol> RodrigoXwiki: yes spaces are still there in the model 13:47 <vmassol> you should read this: 13:47 <vmassol> http://platform.xwiki.org/xwiki/bin/preview/Features/ContentOrganization 13:47 <vmassol> then if you still have questions then report them here as we'll need to improve that doc!

Foswiki also had the webs concept for this. 13:55 <vmassol> "how it translates to the interface now, there's many options".

14:10 <vmassol> ClemensR: sure but OTOH it would totally confuse everyone else 14:11 <vmassol> (since you'd need to explain the concept of spaces and how it's different from nested pages) 14:11 <ClemensR> yeah, I know, maybe name it "top level pages" ?
