  - Data-driven business models are transforming industries, yet small and medium-sized
    enterprises (SMEs) often lack the resources to participate in emerging data sharing
    initiatives. Data spaces provide a federated infrastructure for sovereign data
    sharing, but SME participation remains limited due to complex onboarding processes
    involving technical, organizational, legal, and economic barriers. Data trustees
    have been proposed as intermediaries to facilitate data sharing, but their specific
    role in supporting SME onboarding has not been systematically explored. Here we
    present a reference process for SME data space onboarding and derive four design
    principles, structured along the TELO framework, describing how data trustees
    can address these barriers. Our findings reveal that SMEs require comprehensive
    support throughout the onboarding journey, with particular emphasis on business
    case development. The results offer actionable guidance for data space operators
    and policymakers seeking to broaden ecosystem participation as the European Union
    advances its data strategy.@eng
