I just went through the feature list at CMSMatrix.org and found some inaccuracies:
- "SSL Logins" and "SSL Pages" are possible with the securepages module http://drupal.org/project/securepages
- Test Framework is part of Drupal 7 core which is due out in early 2010.
- WebDav is a Free Add-On http://drupal.org/project/webdav
- Database Reports is a Free Add-On with Views, Table Wizard, and Charts http://drupal.org/project/views http://drupal.org/project/tw and http://drupal.org/project/charts
- Expense reports is a Free Add-On with CCK and Views (http://drupal.org/project/cck)
- Graphs and Charts is a Free Add-On with Views and Charts modules.
- Point of Sale is a Free Add-On with http://drupal.org/project/uberpos
Given that this site is used by many decision makers it's valuable for us to keep this updated and potentially work on filling in the holes where possible. For example, cmsmatrix lists "Kerberos Authentication" as an area where Drupal has no solution, but there are recipes in the forums for getting Kerberos by combining Drupal, Secure Authentication module, and Apache's basic authentication configured to use a Kerberos database. If we can solidify that into a good handbook page we've got one more item finished.
Similarly, the Wikipedia entry is frequently used and frequently inaccurate. I just subscribed to the RSS feed of Wikipedia edits and suggest others do the same so we can make sure it stays accurate.
