Use case development#
Part of the LDT Governance and Trust Framework — instantiates the iSHARE Data Space Template block Use case development (© iSHARE Foundation, see Legal notices).
Purpose#
Use cases are the anchor points of the data space: the concrete reason for stakeholders to participate. Each use case maps stakeholders, data flows, value exchange, outcomes, scalability and replicability.
LDT instantiation — where we stand#
The LDT's applications are worked out as use-case profiles — one page per application, using the template's twelve-part profile skeleton:
| Profile | Owner |
|---|---|
| Cartagena — LEZ, air quality & heat resilience | Ayuntamiento de Cartagena |
| Almelo/Aadorp — Positive Energy District | City of Almelo + Almelo Energie (+ HyEnSys) |
| Aruba Airport — operational decarbonisation | FHC Corp |
| Hamburg Port — logistics twin | Cartagena/ERTICO (liaison) |
| Marketplace & CO₂ tokenisation | Nunsys + LogiNex |
| AI agents & observers | iSHARE + iLabs (Aegean input) |
🧩 Building block requested — Owner: each profile owner (see table)#
What we need: complete your profile page: answer all twelve profile sections, especially data needs & sources, sharing rules needed, and trust requirements — these drive the technical building blocks.
