Welcome to LTD4SCC Knowledge Hub!

The LDT4SSC Knowledge Base Inventory (KB) is the central reference hub of the project Local Digital Twins for Smart and Sustainable Communities (LDT4SSC).
It collects and organises the project’s knowledge outputs, providing stakeholders with easy access to strategies, tools, guidance, and pilots.


What you will find here

  • Strategy & Sustainability – The project’s mission, vision, impact framework, and long-term sustainability strategy.
  • Smart Communities Ecosystem – Links and resources connecting LDT4SSC with European initiatives such as Living-in.EU, DS4SSCC, CitCom.ai, SIMPL, and the EU LDT Toolbox.
  • Pilot Guidance – Overview of open calls for pilots, application process, requirements and recommendations.
  • Resources for Pilots – Technical and non-technical resources, including standards, tools, and frameworks, to guide LDT implementations. Access to the LDT Interoperability Blueprint.
  • Pilot journey – Profiles of awarded pilots, documenting their objectives, datasets, services, and results. Includes the pilot journey documentation and updates.

Why it is important

The Knowledge Base is more than a repository — it is a cornerstone of the project’s strategy and sustainability vision. By consolidating all resources in one place, it:

  • Supports strategic alignment by documenting the project’s mission, vision, impact assessment framework, and sustainability approach.
  • 🤝 Facilitates community building by connecting to major European initiatives such as Living-in.EU, the EU LDT Toolbox, DS4SSCC, CitCom.ai, and SIMPL.
  • 🔗 Strengthens interoperability and innovation by making requirements, specifications, and use cases openly available.
  • 🚀 Empowers pilots and stakeholders by providing guidance, technical recommendations, and showcasing demonstrators.
  • 🔍 Ensures transparency and reuse so that outputs can extend beyond the project’s lifetime.
