Strategic priorities

Five priorities translate the strategy into action. Each carries concrete recommendations for three audiences — pilots, the LDT4SSC consortium, and other stakeholders across local communities and EU initiatives, including policymakers.

Use the tabs under each priority to see what applies to you.

Capabilities that foster sustainability

Sustainability is not a fixed stage of maturity but a dynamic set of conditions that must be sufficiently in place for LDTs to function, generate value and keep evolving.

The strategy maps 18 capabilities across six themes. To stay practical, these are mapped against the requirements (Rq) and recommendations (Rc) already defined in the open-call texts, so they ask nothing new of pilots beyond what the calls specify.

If you are an LDT4SSC pilot

These capabilities map directly onto your call requirements. The strategy's full table cross-references each capability to the specific Rq and Rc codes per work strand — see Table 4 in the source document.

Capabilities are assessed at three levels: the individual LDT, the LDT ecosystem, and LDT4SSC shared assets and services.

1 · Coordinating towards interoperability and multi-stakeholder collaboration

The foundation of a scalable European LDT ecosystem is the ability to connect heterogeneous systems across communities, sectors and borders. Interoperability frameworks and tools already exist, but their consistent adoption and operationalisation remain limited — calling for strong leadership and coordination across initiatives.

  1. Establish clear governance and strategic leadership for LDT development and long-term operation beyond pilot implementation, and describe it in your deliverables.
  2. Stay proactive in identifying opportunities for replication and collaboration through LDT4SSC-wide activities and beyond.
  1. Provide practical guidance and tools for implementing the Interoperability Blueprint, especially through training for awarded pilots and capacity building for end-users.
  2. Build governance and coordination mechanisms to support federation of LDTs beyond pilots.
  3. Facilitate collaboration and replication across pilots and other initiatives — SIMPL, the LDT CitiVERSE EDIC, the EU LDT Marketplace.
  1. Get prepared to participate in the LDT ecosystem by aligning with the Interoperability Blueprint.
  2. Where possible, contribute to standardisation and interoperability efforts, including policy interoperability and the delivery and adoption of legal enablers.

2 · Advancing local digitalisation at scale

Many LDT services remain siloed and non-replicable, limiting reuse and scalability. The focus is on ensuring pilots' LDTs are designed as reusable, modular and replicable solutions addressing shared challenges — so other communities can expand existing solutions rather than developing them from scratch.

  1. Design advanced LDT services with the principle of "replicability by design" — open licensing, clear documentation, use cases and guidance for reuse, and a defined plan for how services will be maintained over time.
  2. Reuse resources and leverage activities provided by LDT4SSC, other pilots, the LDT CitiVERSE EDIC, DS4SSCC-DEP, SIMPL and the EU LDT Toolbox.
  1. Identify shared needs between communities and match them with existing or new solutions contributed to the repository of assets and services.
  2. Support visibility of services through the LDT Toolbox and other channels.
  3. Define clear responsibilities for sustaining assets and services, and for supporting replicators.
  4. Encourage decentralised maintenance by initial developers wherever feasible. In the short term, assume responsibility for maintaining pilot assets only where there is clear evidence of continued relevance.
  1. Reuse and adapt existing solutions instead of developing new ones from scratch.
  2. Participate in collaboration opportunities provided by LDT4SSC.
  3. Provide feedback on usability and applicability.

3 · Demonstrating business and public value

A critical barrier to sustainability is the limited articulation and assessment of the value LDTs generate. Without clear value propositions and capture mechanisms across stakeholders, long-term sustainability stays uncertain. Linking value creation with value capture underpins economic sustainability and supports the emergence of a structured LDT market.

How value is created and captured

  1. Promote LDT services by assessing and demonstrating tangible value propositions across stakeholders — cities, providers, citizens — supporting adoption and replicability. Document this in deliverables and present it in peer-learning sessions and Stakeholder Forum meetings.
  2. Contribute to the evolution of business and governance models (cost-sharing, PPPs) by testing viable alternatives and documenting learnings.
  3. Valorise your services by following the validation framework — converging alignment with the Interoperability Blueprint, the ISAQ assessment, Responsible AI Label badges, MIM8, and LDT Toolbox adoption.
  1. Engage extended stakeholders across the value chain to better understand their business needs and support pilots in addressing them.
  2. Collaborate with other smart communities initiatives to assess market dynamics and identify gaps.
  3. Co-create with pilot representatives a framework for assessing value creation and negotiating value capture across initiatives.
  4. Collaborate with CitCom.ai, the LDT CitiVERSE EDIC, MIM8 and the EU LDT Toolbox towards a full-stack validation service for LDTs.
  1. Test and validate LDT4SSC assets and services' fit to the market, and provide feedback.
  2. Support development of market enablers — funding, procurement, partnerships.

4 · Growing the communities of practice

The LDT ecosystem is inherently multi-stakeholder, requiring sustained collaboration across public authorities, private sector, academia and civil society. The aim is to grow gradually from pilot-driven ecosystems to a mature EU-wide LDT ecosystem, with LDT4SSC acting as facilitator and orchestrator — enabling peer learning and co-creation, especially among stakeholders with differing levels of maturity.

  1. Engage stakeholders across public, private, academic and civil society sectors to identify additional use cases and collaboration opportunities, describing the potential for replication and scaling in your deliverables.
  2. Define KPIs for (a) ecosystem growth around local implementations and (b) collaborations fostered through the EU-wide LDT ecosystem.
  1. Establish a clear engagement funnel: identifying actors → contact-building → fostering participation → achieving contributions to the ecosystem → replication by other communities.
  2. Invest in marketing of the LDT ecosystem and the repository through events, matchmaking and capacity-building activities.
  1. Participate in communities of practice and knowledge exchange across communities and smart communities initiatives.

5 · Strengthening capabilities across all three levels

Sustainability depends on stakeholders' ability to develop and mobilise the necessary technical, organisational and governance capabilities — across individual LDTs, the ecosystem, and LDT4SSC's shared assets and services. This covers organisational integration and governance, technical capacity and interoperability, business and funding models, skills development and knowledge exchange.

  1. Assess and monitor internal capabilities against the 18 capabilities above.
  2. Participate in capacity-building activities provided by LDT4SSC where needed.
  1. Ensure the assets and services provided — the Interoperability Blueprint, capacity-building activities — are fit for purpose to support LDT sustainability and growth.
  1. Disseminate and reuse LDT4SSC capacity-building activities in your communities.
  2. Contribute back by referencing additional capacity-building activities.
  3. Provide long-term support mechanisms — financial and institutional.
  4. Align research, education and innovation with capacity-building needs.

A first edition, to be iterated

As of May 2026 this represents a capability-oriented framework and strategy, to be validated and iterated into a second edition by November 2028, refined through pilot implementation evidence and expanded stakeholder engagement.

Long-term federation responsibilities are expected to be clarified in coordination with the LDT CitiVERSE EDIC, exploring governance and federation mechanisms that could support ecosystem continuity beyond the project lifetime.
