Work Product Release to the Public

We have two projects open to the public:

1. API Design Guidelines: These guidelines cover Open Retailing API Design, including guidelines for JSON design, APIs OAS3.0, transport and security. These can be found at

2. API Data Dictionary: The work can be found at
The dictionary is a work in progress. V1.0 has been released to the pubic for consideration. Members of the public are requested to inform us of missing data elements and objects. Requests for corrections, additions, improvements, and clarifications of the existing elements and objects are welcome. All proposed changes will be reviewed by work groups within Conexxus and IFSF, and potentially be accepted into the Data Dictionary. Changes and additions are reviewed to assure consistency throughout the dictionary and to avoid duplications of the same name being used for the identical element or object. Future revisions of the dictionary may be published to the public.

Please send any feedback to

Member-only released versions can be found here. Be sure to navigate to the tagged version of your choice. Alternatively, Conexxus members may view/download at
