Principles for open data

Open data is an important factor in all development, planning and purchases that FTIA does.  Open data and Open API's are a key factor when renewing old and designing new information systems like the Law for Traffic Services in Finland (2017/320) obligates. FTIA aims to open its data collections for public use in machine readable formats via Apllication Programming Interfaces (APIs).

All public data can be published according to the principles of open knowledge. Before the data is opened, Finnish Transport Infrastructure Agency confirms that there are no legal obstacles for the publication.
