The Drupal coding standards (http://drupal.org/node/318) doesn't explicitly list this point. In addition to .php files using: // $Id$ it seems like .mysql and .pgsql files should also include something like this: -- $Id$ Knowing the exact revision of a .mysql file seems just as handy as knowing it for source (.php, .module or .inc) files. Upon further inspection, I see that this has now been done in core/database/database.* in HEAD. Nice work, Markus and Dries, thanks. a) I'd like to encourage all module developers on this list to add this comment to any .mysql and .pgsql files in their own module(s). b) We should update the coding standards page about this. I'd just add a comment to the page, but it seems better to have it in the body of the node, instead. What's the best way for me to help make that happen? I submitted an issue to the Documentation project's "Developer Guide" component... is that the desired behavior? Thanks, -Derek
