The OASC (Open & Agile Smart Cities – founded by the Future Cities Catapult among others) has developed a set of three ‘minimal interoperability mechanisms’ which have been formally adopted by 130 cities in 28 countries:
- Context information management API which permits access to real-time context information from different cities.
- Shared data models – Guidelines and catalogue of common data models in different verticals to enable interoperability for applications and systems among different cities
- Marketplace API – this is the OASC ecosystems transaction management MIM – it exposes functionalities such as catalogue management, ordering management, revenue management, Service Level Agreements, license management and is complemented by marketplaces for hardware and service
