Federation Trust Registry

Full Title or Meme

Wherever a Web Sites wishes to take advantage of the benefits of belonging to a Federation it needs to be exposed in a Data Service that allows any user to ensure that the Web Site has been Validated by the Federation.

Context

Several variations on the theme of a Federation Trust Repository exist already.

• Trust Services of TSCP the Transglobal
• UK Open Banking
• Recognized Coordinating Entity (RCE)

Solution

In order that a Federation can be expose both is principles and its membership to the public some data server needs to provide information about the existing membership and their status. There are two ways to do this:

1. A list of the members and their status that can be viewed in a browser.
2. A data service that exposes the contents of the site in machine readable format.

This page is about the later case.

Of primary importance for a Federation that wants to allow user's to trust the members, is some easily accessible data service on a site that meets the following criteria

1. Reliable, always-on accessibility.
2. Meta-data descriptions of the contents of the site.
3. Machine readable data as well as meta-data (called Service-Enabled Data Store).
4. Data Security
