Re: [xwiki-devs] [RFC] XWiki Query Language

Hi there, Actually, interestingly enough, after looking for a few secs at xpath and understanding a bit better how it works (thanks Wikipedia) I found it easy to understand. Provided users can find a treeview of how XWiki underlying elements work involved on XWiki.org it could be easy to use... In fact, rather than the query language itself I think the main issue for people starting to use XWiki is that it's hard to find what exactly are the XWiki elements (object, classes, etc) and how to build queries around them. Having various query languages is great because developers can use the one that they are the most familiar with. But for XWiki beginners what is really needed is a clear documentaiton page saying something like : "If you want to query property A from object B in space C here are the XWiki bits involved : - in hql : BaseObject, doc.web, prop.id.id (or whatever) - in xpath : /*/*[space/Main/ and and obj/XWiki/XWikiUsers/ @xp:email like 'XXX']" providing examples, explanations, and so on... As a XWiki beginner I don't even know what a query language is, yet I may want to build applications -> I need to know how I should go about doing this.

Having an automated query builder might be the best answer to this issue though... Not necessarily ;-) Guillaume
