PARTHENOS stands for Pooling Activities, Resources and Tools for Heritage Eresearch Networking, Optimization and Synergies. It provides a thematic cluster of European Research Infrastructures, integrating initiatives, e-infrastructures and other world-class infrastructures, and builds bridges and provides common solutions to similar problems, between different, tightly interrelated fields. The project, funded by the EC in the framework of H2020 Programme, is creating a common ecosystem to support Humanities, Language, Cultural Heritage, History and Archaeology Research. The project is driving interoperability of tools, applicability of common standards, shared policies on IPR, Open data and Open Access. The ICCU has the task to identify the user requirements of the many communities involved, such as History, Language Studies, Social Science, Cultural Heritage, Archaeology, and related fields across the (Digital) Humanities, about data policies and to implement common policies and strategies for accessing research data, taking into account issues on IPR, Open Data and Open Access. It also contributes to the definition of a common framework for Interoperability and semantics and as content provider, in delivering data from cultural institutions.
