Editing EPrints Glossary (section)

=== Ingredient ===
Since [[#EPrints repository software|EPrints]] version 3.4, the concept of [[EPrints Ingredients|ingredients]] has been introduced along with [[#Flavour|flavours]].  The main purpose of ingredients is to allow complex functionality to be developed but deployed in a way that does not make a mess of the existing [[#Core codebase|core codebase]] by spewing files in different places, like some [[#Bazaar plugin|Bazaar plugins]] can do.  Also, as Bazaar plugins are designed to be one-click install, they should require limited configuration, as this takes away from ease of deployment that one-click install implies.  Instead, ingredients can be much more complex.  Although effort should be taken to avoid mixing distinctly separate pieces of functionality when they could be kept apart.  

Typically, an ingredient would be deployed by checking out a tagged version of the Git repository for that ingredient on [https://github.com/ GitHub].  Although that requires more technical knowledge than a one-click install, this is also inherently a safety feature, to avoid accidental installation of new functionality that could damage the data stored by the [[#Repository|repository]], which could happen when installing some of the more complex Bazaar plugins, without understanding of how they behave.
