Welcome to the LDT4SSC Knowledge Hub
The Knowledge Hub is the central reference point for Local Digital Twins for Smart and Sustainable Communities (LDT4SSC). It collects the project's outputs — strategy, guidance, technical resources and pilot work — and keeps them openly available for reuse beyond the project's lifetime.
Sections
-
Strategy & Sustainability
The project's mission, vision and values, alongside the Framework and Strategy for Growth and Sustainability: what sustainability means for LDTs, four possible futures for the ecosystem, value creation, and five strategic priorities.
-
Smart Communities Ecosystem
The European initiatives LDT4SSC connects to — Living-in.EU, DS4SSCC, CitCom.ai, SIMPL, the EU LDT Toolbox, the LDT CitiVERSE EDIC, and the data space and CitiVerse landscape.
-
Pilot Guidance
Requirements and recommendations per work strand, plus implementation guidance: reference architectures and step-by-step workflows for interconnecting, building and extending LDTs.
-
Resources for Pilots
Technical resources — standards, tools and frameworks — and non-technical resources including the LDT4SSC Methodology, impact assessment, legal and AI guidance.
-
Pilot Journey
The awarded pilots: objectives, datasets, services and results, with updates published as the work progresses.
-
LDT Interoperability Blueprint
Building blocks, workflows and reference architectures for building an interoperable LDT — co-created with the pilots and under active development.
Purpose
The Knowledge Hub is more than a repository. By consolidating resources in one place, it:
- Documents the strategy — mission, vision, impact assessment and the sustainability framework guiding the project;
- Connects the ecosystem — linking LDT4SSC to related European initiatives, standards and infrastructures;
- Supports interoperability — making requirements, specifications and use cases openly available;
- Equips pilots — guidance, technical recommendations and demonstrators;
- Enables reuse — so outputs remain usable after the project ends.
Open calls
All three rounds of open calls have closed. To follow the community, join the Stakeholder Forum, or see the Pilot Journey for the pilots already underway.
