Welcome to the DINI stage @PIDapalooza! Join us when we go backstage to find out about how PIDs shape the character of the "2019 DINI Certificate for Open Access Publication Services". Since 2003 six editions of this hot and high quality standard for open access repositories and journals and around 100 institutions in Germany went wild to get it. After this short backstage visit which gives an intro to DINI, the German Initiative of Networked Information, the DINI Certificate will do a stage dive into the session crowd presenting all its songs (requirements and recommendations) that deal with PIDs. In a discursive jam session all party people (virtually) shout out their opinion on these criteria by either celebrating or throwing tomatoes.
