The objective of ALMASI is to provide the research community with an aligned, nonprofit, high-quality, and sustainable scholarly communication ecosystem across three world regions: Africa, Europe, and Latin America. This will enable scholarly communities to take full responsibility for innovative, valid, reliable and accessible publishing services and solutions that do not charge fees to readers or authors, commonly known as Diamond Open Access. This aligned nonprofit publishing ecosystem will take into account specific needs across the diversity of disciplines, global regions, and languages. The project will achieve this goal by concentrating on measures that will harmonise and strengthen existing nonprofit publishing services and solutions. ALMASI will establish a framework for knowledge transfer, coordination, and alignment of non-technological publishing skills, services, and solutions. The project will focus on (1) mapping nonprofit publishing services and solutions across the 3 regions; (2) aligned quality support instruments for publishing services; (3) shared training materials and curricula for publishing services, journal editors, and publishing staff; and (4) long-term financial sustainability and OS policies for scholarly publishing. The project will be carried out in the context of the nascent Global Diamond Federation, which is supported by UNESCO.
