Installable with the Extension Manager


This is a really experimental application at this point.


The following features have been implemented:

  • A scheduler job to compute scores based on the Activity Stream events
  • A page listing the scores
  • The ability to add Rules by creating pages having ActivityRanking.RankingRuleClass
  • Some existing rules:
    • Add points when a document is created (+2)
    • Add points when a document is modified (+2)
    • Add points when a comment is added (+1)
    • Add points when a blog post is added (+12)






What needs to be improved:

  • Add event normalization process since for example adding a comment does 2 things: add the object and modify the document. The rule objects should only see a single event.
  • Add rules
  • Work on scores for the rules
  • Improve the UIs in general
  • Add score information on user's profile
  • Add a top score panel
  • ... and a lot more

Prerequisites & Installation Instructions

We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager). Note that installing Extensions when being offline is currently not supported and you'd need to use some complex manual method.

You can also use the following manual method, which is useful if this extension cannot be installed with the Extension Manager or if you're using an old version of XWiki that doesn't have the Extension Manager:

  1. Log in the wiki with a user having Administration rights
  2. Go to the Administration page and select the Import category
  3. Follow the on-screen instructions to upload the downloaded XAR
  4. Click on the uploaded XAR and follow the instructions
  5. You'll also need to install all dependent Extensions that are not already installed in your wiki

Trigger the Activity Ranking Job scheduler so that it starts computing scores.
