The complete assessment, the impact and cost/benefit ratio of the activities of E-RIHS, depends on the knowledge of the overall size of the resources made available by the E-RIHS Members through the appointed national nodes as well as on the value of the resource specifically committed to the activities of E-RIHS. In a broad sense, in-kind contributions represent the capital of European Research Infrastructure Consortia, whose Members, in the proper sense, are the Governments of the involved States. The goal of E-RIHS, the European Research Infrastructure for Heritage Science, is to grow and strengthen a creative, European-wide framework for supporting frontier research in heritage science. It will do so by offering access to expertise, data and technologies through a standardized approach based on different modes of services organized in four platforms: • ARCHLAB (access to heritage archives and collections); • DIGILAB (remote access to data and tools for heritage research); • FIXLAB (access to large-scale facilities and advanced laboratories; • MOLAB (collections of mobile instruments enabling in-situ diagnostics). The scope of D3.4 is represented by the identification of the main foreseeable types of in-kind contributions as well as by the definition of a methodology for the accounting of in-kind resources, taking into-account the specific needs of E-RIHS.
