ARIADNE is a research infrastructure for archaeology. Its main objective is to support research, learning and teaching by enabling access to digital resources and innovative new services. ARIADNE does this by maintaining a catalogue of digital datasets, by promoting best practices in the management and use of digital data in archaeology, by offering training and advice, and by supporting the development of innovative new services for archaeology. The datasets that are registered in the ARIADNE catalogue are held by its partners and have been created through research, in excavations, in fieldwork, laboratory and other projects. In recent years archaeologists have been making increasing use of sophisticated digital equipment and techniques. During the course of a research project large volumes of data are created and collected, and become part of the research archive. ARIADNE aims to make these archives available through its portal for researchers to consult when starting new research.
