The ARIADNE Research Infrastructure (RI) is the evolution of the EU-funded ARIADNE data infrastructure projects. It is a not-for-the-profit association (AISBL) established according to Belgian law, operating worldwide. Currently led by PIN (Italy) and ADS (UK), it has 32 research institutions as members, cooperating to integrate archaeological datasets and make them findable, accessible, interoperable and re-usable via its catalogue and its powerful semantic search engine. The ARIADNE RI supports archaeological synthesis by enabling researchers to distillate relevant information from archaeological digital data.
