Overview
ISO/TR 19174:2025 - Geographic information - Securing interoperability among heterogeneous city domain information models - is a Technical Report that analyzes how to secure data interoperability in smart-city environments. The document focuses on the data component of a Spatial Data Infrastructure (SDI) and on extending the meta model framework for interoperability (MFI) to enable consistent sharing and reuse of heterogeneous city domain information models. It includes a review of relevant standards and best practices, a registration-and-mapping use case using a model registry, and a set of technical requirements and recommendations for further standardization.
Key technical topics and requirements
- Interoperability analysis: identification of interoperability issues across city domain information models (system, semantic and registry interoperability).
- Meta model Framework for Interoperability (MFI): guidance on applying MFI interoperability elements to support smart city services and cross-domain data exchange.
- Model registry & repository concepts: using a model registry to register, discover and map domain models; integration with metadata registries (MDR) and registries-of-registries (RoR).
- Standards mapping and review: assessment of smart-city, geospatial, IoT and data management standards (e.g., ISO/IEC JTC 1 WG 11, ISO/TC 268, OGC, INSPIRE, OASC MIMs) to identify gaps and alignment opportunities.
- Technical requirements: concrete requirements for registration, mapping, metadata capture (registry summary), and applying MFI elements to enable semantic alignment and service interoperability.
- Use case example: a registration and mapping scenario demonstrating how model registration can secure interoperability among different domain models.
Practical applications and target users
Who will use ISO/TR 19174:2025:
- City planners and smart city program managers seeking consistent data exchange across departments and vendors.
- SDI architects and GIS professionals implementing cross-domain geospatial services and digital twins.
- Standards bodies, registries and platform vendors designing model registries, metadata registries or registry-of-registries.
- System integrators and software developers working on semantic mapping, API design (e.g., OGC APIs, NGSI-LD), and data harmonization for urban services.
Practical uses:
- Establishing model registration workflows to make city information models findable and reusable.
- Defining registry and metadata requirements to support semantic interoperability for urban data (assets, infrastructure, temporal/spatio-temporal attributes).
- Informing procurement and technical specifications for interoperable smart-city platforms and digital twin implementations.
