Preface: Proceedings of ArcheoFOSS XIII Workshop—Open Software, Hardware, Processes, Data and Formats in Archaeological Research

The meaning “open approach” in archaeology today probably implies a lot of different, disconnected, and even contrasting activities. The 2019 congress proceedings respect and emphasize such multiplicity. The essays vary from Python script for implementing a classification method in QGIS, different applications of free GIS, WebGIS and databases for implementing information and for tourism, Qfield app in QGIS, how free licenses are an important aspect when sharing knowledge, Bot for Telegram, the use of real-time open-source software and hardware, innovative uses in archaeology of Digital Terrain Models from satellite data, and spatial data management. The scientific soundness of articles defines the possibility, in the archaeological field, to use new and open technologies to raise the consciousness of tourists and to help researchers. The result is a faceted analysis of the state of the art of whatever may be defined as an “open approach” in archaeology.
