Scope

This document analyses a feasible way to accommodate interoperability elements for the data component of a spatial data infrastructure (SDI) and extend the meta model framework for interoperability (MFI) in securing interoperability among heterogeneous domain information models under the smart city context.

This document:

a) outlines the interoperability issues for city domain information models;
b) reviews relevant standards and best practices and examines methodologies or solutions to tackle the interoperability issues;
c) supposes a use case and provides an example to secure interoperability among different domain information models using model registry;
d) specifies technical requirements in concern about how to apply the interoperability elements of the meta model framework to support the interoperability of smart city services;
e) highlights the standardization items to be developed to secure interoperability

Supporting the following Sustainable Development Goals:

	(Indirect support) ISO/TR 19174 enables robust digital and data infrastructure by supporting interoperability between diverse city and geospatial information models, facilitating scalable, standards‑based innovation across urban information systems.
	(Indirect support) By improving the consistency and interoperability of urban data, ISO/TR 19174 supports more informed planning, management, and operation of city systems, indirectly contributing to more sustainable and resilient cities.
	(Indirect support) The guidance promotes shared approaches to interoperability across organisations and sectors, enabling collaboration and coordinated data use among stakeholders involved in city and geospatial information ecosystems.
