magnolia-module-shop offers default shop functionallity for the Magnolia CMS. In its core, it provides a flexible data structure and a set of classes for handling the data. It is then up to the integrator to define the look and behavior of the shop - however it also comes with a set of default paragraphs for the "pop" theme of the Magnolia Standard Templating Kit.

The data model is pretty straight forward and resembles well known shop systems like osCommerce or others. Its key features are:

• Multilingual: Each entity which needs to be described has several description entities (one for each language)
• Multiple price categories / currencies: Each product can have several prices (one for each price category). Each price category is of a certain currency.
• Hierarchical product categories: Product categories are structured in a hierarchical way. To keep thinks simple, a product category can only have one super category. If multiple super categories are absolutely necessary for an integrator "shop category aliases" can be used (i.e. shop category "copies" which reference an other shop category).
•  Multitenancy: This has no direct affect on the shop module. To allow the setup of multiple independant shops in one magnolia, the whole data structure will be copied several times and kept in their own data folders.

In addition to the entities shown in the diagram above, the products now also support option sets and options.

The following is a very compact list of features the shop module should offer/support. The number in parenthesis before each requirement refelcts the priority of the feature where 1 means "an absolute necessity" and 3 "nice to have" or "at a later release".
