PmWiki
PmWiki is a Wiki software package, similar to other wiki packages, such as MediaWiki and TikiWiki. It's a PHP application which by default uses flat-files for storage.
Features
PmWiki is able to be configured to utilize MySQL, MS SQL, as well as a variety of other data stores through it's plug-in system. Upgrades consist of un-compressing the archive on top of previous installations, with no need for re-customization as long as the proscribed good practices are followed.
Design
The current version of PmWiki is 2.2.13[1]. The core package is very feature-limited, as proscribed by the PmWiki philosophy of keeping everything in the core to a minimum, and allow ease of extensibility.[2]
The following things are built into the core: Basic user authentication, core markup, and file history management. Features available though plug-ins (called Recipes) are:
- Multiple data stores
- Extended markups
- Skins
- Forum integration
Certain directory structures are considered off-limits for the core application to touch. The following directories are not modified in any way during upgrades: ./local, ./pub, and ./cookbook. This allows for any customization of the application to avoid overwrites during upgrades.
Basic access control is turned on by default, allowing a single password to control permissions to read, edit, and administer the wiki. These can be set site-wide, or per Wiki Group. Through the core authentication system (Known as AuthUser), this can be changed to use a user name and password combination, rather than just a password.
When using AuthUser, several options are available for identity stores, to include LDAP, Active Directory, Database tables, or htpasswd and htgroup files.
