The C5 includes representatives of each government that has agreed to join the initiative. Each government designates a lead institution/institutions to participate in this collaboration.
In the first year of the C5, the membership consisted of representatives from the five founding governments: Colombia, France, Mexico, United Kingdom and Ukraine. Argentina joined as a full member later.
The Open Contracting Partnership (OCP), Open Data Charter, Open Government Partnership (OGP), World Bank, European Bank for Reconstruction and Development (EBRD) and Organisation for Economic Co-operation and Development (OECD) are leaders in global policy and practice. They are invited to join the C5 as ex-officio members and supporters. The OCP and OECD have offered to provide organizational support to the C5 initiative.
The group will be open to include additional countries that meet the aspirations in this charter upon consensus by our members. The Chair may also invite other countries to join us in meetings and specific initiatives as appropriate.
Each of our countries will designate a lead institution or institutions to participate in this collaboration of specific initiatives therefrom and reach out to an additional appropriate civic representative. We will decide on a case by case basis how any joint initiatives will be funded and resourced.
Our Charter is not legally binding but based on a voluntary collaboration between innovators in our governments. It comes into effect on the date of the signature by a Ministerial or other high-level representative and will continue to have effect for a period of five (5) years unless terminated by a signatory government, giving three (3) months written notice to the current Chair.
We recognize the role of the Open Contracting Partnership, Open Data Charter, Open Government Partnership, the World Bank and the OECD as leaders in these global policy and practice areas and invite them to join us as ex-officio members and supporters to make sure our lessons and insights are available to assist their members with their own learning and open government aspirations.
