The Concordat has grown from strength to strength over the last three years, and this May we celebrate its third anniversary. On the 11th of May we will host an all-day OpenSpace event to discuss the impacts of the Concordat and its future direction. The 16th of May will be a day of celebration as we invite all signatories to take part in our #ConcordatOpenness Twitter campaign. Tweeting about the Concordat and openness activities using the hashtag #ConcordatOpenness will not only help promote the Concordat but it will celebrate all the fantastic engagement activities our signatories have organised over the previous 12 months.
