IDA is a storage service for research data provided by the Ministry of Education and Culture to actors in the Finnish research system. The service is produced by CSC – IT Center for Science (CSC). IDA enables the safe storage of research datasets and related metadata. Access to the data may be granted within the research project or for a wider group of users. The service is intended for stable research data, both raw data and processed datasets. Owners of the data decide on the openness and usage policies for their own data. The service is not intended for data containing sensitive personal data. The data stored in the service must be connected to a research project. The person responsible for the project acts as a contact person towards the service provider and decides who can access the data in the project. Users may belong to one or more projects. Data stored in IDA is checked for viruses and integrity upon receipt. Data is automatically copied and the integrity of both the original files and copies is monitored. The service is offered to Finnish universities and polytechnics as well as projects and researchers funded by the Academy of Finland.
