I'm setting up an xwiki instance for use in a school class while the students are working in groups on different projects. The teacher wants to be able to keep an eye on what each individual student is actually contributing, so I'm trying to make a report that shows:

1. a list of all documents to which a student has contributed 1.1 a list of all versions of this document that the student changed/updated

Has anyone done anything similar? Right now I'm a bit at a loss, as it seems I have to run thru all the versions of all the docs in the entire xwiki. Might there be a better way?

I haven't done this but maybe you could turn the stats on for your wiki and use the generated stats to extract the 2 reports you want.

I ended up writing a snippet that checks all the revisions of all the docs on the wiki. Not pretty, and it won't scale, but works for my purpose. And in case it will work for someone else, I contributed it here: http://www.xwiki.org/xwiki/bin/view/Code/ ChangesByUserSnippet

Thanks for your contributions, they're very cool :)

And maybe somebody even has a suggestion for making it more efficient?

Have you tried using the statistics apis I mentioned above? I haven't used them yet so I can't refer you to some code snippet but they're used on the Admin.Stats page (it'll be empty if you haven't turned on stats in xwiki.cfg). There are also apis for them in $xwiki and in $context (you'll need to check the XWiki and Context java classes though to know more). Note that we also have a jira issue for refactoring the Admin.Stats page: http://jira.xwiki.org/jira/browse/XWIKI-1267 Thanks -Vincent
