Basic ideas are presented of a multi-national research project to share data about the Roman city of Aquileia employing the Information and Communication Technologies (ICT). A Consortium is proposed to manage the project, adopting the Open-source approach to the software design. The Consortium proposes a common vision of the data which we detail in the paper. There results a shared vocabulary of terms and meanings, as well as standard metadata formats to encode, classify and exchange data from whatever source. A federated system of computer resources realizes and supports the project. We also discuss the results to be realistically expected in short time of a low-cost, joint research effort.
