In task 5.7 (Open Linked Data. Archaeology Case Study), a virtual reconstruction of the Roman theatre in Catania has been created as an example of a transition of archaeological data to the cloud, i.e., from data silos on individual computers to webservices. The case study is based on a unified workflow that starts with the archaeological documentation and results in a virtual reconstruction. The data was processed in the Extended Matrix (EM) system that has been developed by the ITABC.
