  With new emerging technologies, such as satellites and drones, archaeologists
collect data over large areas. However, it becomes difficult to process such
data in time. Archaeological data also have many different formats (images,
texts, sensor data) and can be structured, semi-structured and unstructured.
Such variety makes data difficult to collect, store, manage, search and analyze
effectively. A few approaches have been proposed, but none of them covers the
full data lifecycle nor provides an efficient data management system. Hence, we
propose the use of a data lake to provide centralized data stores to host
heterogeneous data, as well as tools for data quality checking, cleaning,
transformation, and analysis. In this paper, we propose a generic, flexible and
complete data lake architecture. Our metadata management system exploits
goldMEDAL, which is the most complete metadata model currently available.
Finally, we detail the concrete implementation of this architecture dedicated
to an archaeological project.
