# Getting started

The Data Owner role is fulfilled by a legal entity that has one or more rights to a service provided by a Service Provider. These rights, or entitlements, are established in a legal relationship between the data owner and the Service Provider.

The Data owner, Service Consumer and Service Provider roles can be fulfilled by the same entity i.e. a legal entity that consumes a service based on its own entitlements to this service (for example, a trucking company's entitlement to request Estimated Time of Arrival and optimal route information) but this is not necessary.

Entities entitled to a service can delegate others to consume it on their behalf. In such cases,, the consuming entity operates based on another entity’s entitlements. In these cases, the Service Consumer uses a Service Provider’s service based on the Data Owner’s entitlements, but the role of Service Consumer is performed by a different entity than the Data Owner.
