About ECI Online Collection Software (OCS)

In the context of European Citizens' Initiatives (ECI), the Online Collection software (OCS) is a tool for online data collection. OCS enables citizens to support a given initiative and organizers to manage its operations. The tool also streamlines both data collection and its verification by the National Authorities.

OCS respects the Regulation (EU) No 211/2011 and Regulation (EU) No 1179/2011 of the European Parliament and of the Council. Within ISA action 1.12, the European Commission contributes to its development with the aim to provide a generic tool available to all initiative organizers. OCS is made available under a EUPL license.

The relevant downloads of the OCS tool are to be found under the Download releases button.

More information is available on the ECI Register.
