# BDI Technical Roles ## 1. Introduction The building block aims to define BDI's technical roles, including Identity Provider, Identity Broker, Association Administrator, Data Owner, Data Service Provider, and Data Consumer. Each role plays a crucial part in managing identity, data control, and service provision within BDI's framework. ## 2. Purpose of this building block The purpose of this building block is to define the technical roles in BDI. ## 3. Concepts The technical roles of the BDI are given and explained below.
