As part of the long road to creating an Auction System for Xoops, the first module "Code Data management" (CDM) has been released and can be downloaded at here.

What does it do?
CDM offers the following functionality;
* Provides a central repository for all codes that may be used in one or more Xoops applications
* Provides central management of code data utilising Xoops group authority mechanisms
* Provides a program API based on xoopsObject that can easily extended for additional application functionality

CDM is a something for the application developer's toolkit rather than an end user app. Further info at the author's website
