We would like to create an addon for osCommerce.
The idea is to add microdata to the HTML content describing products, categories, shopping cart contents, user information and completed orders. It also has to be able to add a <script> -tag to the <head> element, and either be able to automatically add two HTML blocks to pages, or it should be easy for the users to add these.
The addon would collect the microdata using Javascript, and send it to a web service. The service collects the data, and provides product recommendations based on what the user is viewing or has searched for (from the same store) through the HTML blocks that have been added to the pages.
We were unable to find any developer guides or information on the processes related to publishing addons on your site, if there are special requirements, and approval processes to consider.
Can you tell us where we could find this information, so we can better evaluate the amount of work necessary to create the addon?
