Open data is publicly available data that can be universally and readily accessed, used and redistributed free of charge. It is structured for usability and computability.

As part of the activities of Action Group 5, a study was developed to identify the open data initiative leaders, study current policies and legislation framework on privacy, data protection, information access rights, disclosure policy, study the structure (different skills, decision making models, capacity to work with open data, data flows) and current status of data and datasets, analyse the demand for open data, identify potential champions with regard to data users, identify how this would be financed and study the technical infrastructure.

Last but not least, guidelines and recommendations for the Open Data Alpine Space were proposed.
