Representatives of 23 cities from around the world have met in Dublin to agree a set of principles governing the definition of what a 'Smart District' in a city should be.
It is the first time such a declaration has been made by a group of chief technology or information officers from leading smart cities.
The 'Dublin principles' as they are known will enable cities to measure progress as smart districts emerge around the globe

The City Digital Profile group from the European Telecommunications Standards Institute (ETSI) and members of the City Protocol Society were also in attendance.
Dublin's Smart Docklands District, where 70,000 people live and work, was used as an example of what such an areas can look like.
The group also examined the challenges of building and growing smart districts in different places around the world in a way that brings benefits for citizens and businesses.
The attendees also looked at smart vehicle technology, including the latest vehicles being used by gardai, and discussed the use of technology in providing improved safety and security for people.
"Dublin City Council is in a unique position to act as an 'honest broker' and bring together stakeholders who want to trial innovative new solutions to challenges faced by our cities in collaboration with technology companies, entrepreneurs and researchers on the ground," said Owen Keegan, Chief Executive of Dublin City Council.
