IPERION CH aims to establish the unique pan-European research infrastructure in Heritage Science by integrating national world-class facilities at research centres, universities and museums. The cross-disciplinary consortium of 23 partners (from 12 Member States and the US) offers access to instruments, methodologies and data for advancing knowledge and innovation in the conservation and restoration of cultural heritage. Fourth in a line of successful projects (CHARISMA-FP7, Eu-ARTECH-FP6 and LabS-TECH network-FP5), IPERION CH widens trans-national access by adding new providers with new expertise and instruments to the three existing complementary platforms ARCHLAB, FIXLAB and MOLAB. The quality of access services will be improved through joint research activities focused on development of new advanced diagnostic techniques and (with DARIAH ERIC) tools for storing and sharing scientific cultural heritage data. Networking activities will (a) promote innovation through technology transfer and dynamic involvement of SMEs; (b) improve access procedures by setting up a coordinated and integrated approach for harmonising and enhancing interoperability among the facilities; (c) identify future scientific challenges, best practices and protocols for measurements; (d) optimise the use of digital tools in Heritage Science. To advance the international role of EU cultural heritage research, IPERION CH will generate social and cultural innovation by training a new generation of researchers and professionals and by worldwide dissemination and communication to diverse audiences. To ensure long-term sustainability, the advanced community of IPERION CH will work towards inclusion in the new ESFRI Roadmap and constitution of a RI with its own EU legal entity (e.g. ERIC). Synergies with national and local bodies, and with managing authorities in charge of ESIF, will expand the scope and impact of IPERION CH in terms of competitiveness, innovation, growth and jobs in ERA.
