# Role Mapping

The iSHARE Trust Framework defines a set of roles that apply to legal entities participating in data sharing ecosystems. These roles are designed to align conceptually with those used in complementary initiatives such as IDSA, DSSC, and regulations like the EU Data Governance Act. Although each initiative has its own approach to defining roles, the comparison table below provides an overview of how these roles relate to one another. This helps create a shared understanding across data space communities and supports interoperability and trust.

**Other relevant roles**

These roles are necessary in the framework and data spaces context however, they are not necessarily registered as participants. The roles will still be essential to enable trusted data sharing and governance around it.
