SPIP (Système de Publication pour l'Internet) is a free software content management system designed for web site publishing, oriented towards online collaborative editing.
The software is designed for easy setup, use and maintenance, and is used in public and private institutions. The last P in the word SPIP stands for both Partagé (shared) and Participatif (participative), in the sense that the software is designed for collective online editing. Its mascot is a flying squirrel.
It is used both by institutional sites, community portals, academic sites, personal webpages, and news sites.
The software is written in PHP, and relies on one or more databases: SQL, SQLite or PostgreSQL.
The pages of the site are generated 'on the fly': the contents stored in the database are formatted through presentation 'skeletons' that merge HTML and SPIP's own markup language. A caching system avoids the generation of pages at each request: when a page is requested, SPIP checks if it doesn't exist in its cache and if it isn't too old, it will be displayed. The life-span of a page is adjustable in its presentation skeleton.
SPIP was originally conceived for the uzine.net site, after which its designers released it under GPL License. Since its launch 2001, it has also been used for Le Monde diplomatique newspaper and www.vacarme.eu.org; the webmaster of Le Monde diplomatique is one of the initiators of SPIP,
SPIP integrates a cache mechanism, an authentication system, an automatic setup module and an interface for administration and input of articles. SPIP can create dynamic pages without any PHP knowledge, using a web template system known as 'skeletons.
