The Community Cluster offers a discussion forum for the heterogeneous Experimental Archaeology community -from professional scientists (e.g., larger international associations like EXAR and EXARC) to interested laypeople (Citizen Scientists). This allows discussions about interoperability standards and the application of FAIR principles to collected research data, such as community standards, ontologies, controlled vocabularies, and exchange formats. The focus is particularly on RDM-related discussions about the FAIR and understandable machine-readable publication of research data related to Experimental Archaeology (hypothesis testing, experimental design and reporting, etc.), as well as the publication of white and blue papers on ontologies and good/best practices.
