This document reports on the approach that will be adopted by E-RIHS IP for setting up a collaboration strategy with relevant projects and research infrastructures at EU and global level towards the establishment of common practice policies in the framework of the future European Research Infrastructure Consortium (ERIC). This strategy is based on previous advances aiming at the same goal of precedent or still ongoing projects, like E-RIHS PP and IPERION HS, and will be described here in terms of objectives and methodology. The set of concrete actions proposed will ensure that existing links with other European Strategy Forum on Research Infrastructures (ESFRI) projects and landmarks and international research infrastructures and consortia, operating in physical, natural science and social and cultural innovation domains, are fully exploited and that new links with other relevant initiatives are created.
