Geographic information. Securing interoperability among heterogeneous city domain information models. | Status: Current

1 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:

1. a) outlines the interoperability issues for city domain information models;
2. b) reviews relevant standards and best practices and examines methodologies or solutions to tackle the interoperability issues;
3. c) supposes a use case and provides an example to secure interoperability among different domain information models using model registry;
4. 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;
5. e) highlights the standardization items to be developed to secure interoperability.
