6Aika Open Data and Interfaces

Scope and Objectives

The main target of The Six City Strategy (6Aika) Open Data and Interfaces Spearhead Project is to boost data driven business by harmonising APIs and datasets, which enables the scalability of applications built on a specific city API to other cities providing a harmonised API. The cities have focused on four domains: participation, events information, decision making, and resource reservation.

The aim is to make the opening up of data a natural part of the normal operation of cities, thus helping them facilitate the creation of data-based services and business even after the completion of the project.


DataBusiness.fi involves the business sector in active cooperation so that operators can share their own data needs, influence the interface solutions and standards chosen, utilise the open data provided by cities and open up their own data for use by others.


The total budget of the 3,5 year project (1 July 2014–31 December 2017) spearhead project is 7,5 million euros.

Six City Strategy (6Aika)

The six largest cities in Finland have joined forces to tackle their common urban challenges. The Six City Strategy 
(6Aika) is implemented with cooperative projects which enable the cities to experiment in a larger context than just one city. They engage the
 whole urban community to create smarter and more viable cities.
