The iSHARE Trust Framework is a collaborative effort to improve the exchange of data between organisations in and across data spaces. The iSHARE Trust Framework is available [here](https://framework.ishare.eu).

**Technical Approach**

Unlike traditional software infrastructures, iSHARE offers a “soft infrastructure” focusing on:

* Identification, authentication, and authorization for machine-to-machine (M2M) and human-to-machine (H2M) communication via REST API.
* Public Key Infrastructure (PKI) for authentication.
* Signed JSON Web Tokens (JWTs) for message integrity.

Data sharing transactions must align with the [iSHARE Trust Framework’s roles](https://framework.ishare.eu/main-aspects-of-the-ishare-trust-framework/framework-and-roles), each with specific responsibilities and interactions. This portal provides everything needed to technically implement iSHARE in your organisation, including:

* How to get started for each role.
* All iSHARE technical specifications.
* Definitions for all endpoints required per role.
