Each application will have its own model for plugins. Much of this model will be common across applications but there will always be issues specific to a particular applications’s plugins. Some of the issues that need to be taken into consideration:

* Plugin dependencies
* Plugin resources like JavaScript files or images
* Configuration metadata and default configuration values
* Extension points that plugins might expose
