A system and method for modularized Web provisioning. Functionalities available for Web provisioning are modularized into individual feature files. A site template may reference one or more of such features. A site provisioned using the site template activates the referenced features by default. Features may be added to or removed from the site. A feature may include atomic Web provisioning elements, custom code, metadata specifying properties of the features, and/or activation dependency information specifying precedent features that need to be activated before the feature can be activated. Feature provisioning can be processed through a command-line tool, an object model, and/or a graphic user interface.
