Gentlemen, I run around 290 small thematic citizen research wikis (nr being developping) under an old mediawiki version (I fear an upgrading hassle). In order to simplify their set-up I systemized them in using a script to build the symbolic directories from a unique central one, so I only have to build the LocalSettings.php, the images directories mainly for the wikilogo.gif particular to the site and to enter the templates manually. To be sure I can move them around without too much pain and keep them under their own password, I use SQLite . Round 20 minutes set-up each. With a friend we would like to transfer all this under MYSQL (or MariaDB?) in order to share template and WikiDB. Possibly on several machines. Possibly developping some extension on the middle range. Possibly transfering further on under another database system (to mix diffect entries and mail entries). I feel we would first need to study a conceptual block map of the MediaWiki architecture, internal exchanges and database requests. Does that exist ? Also, in order to manage the whole thing advisably I would need two tips: 1. is there a secure/reliable method/extension to protect pages on a per page basis ? 2. how to get on a daily basis the access count of the wiki pages ? Thank you ! jfc
