This class describes the general concept of archaeological escalation intended as a coordinated set of excavation process units (A1) performed on an area considered as part of a broader topographical, rural, urban, or monumental context. An archaeological excavation typically takes place in a predefined geographic area specifically defined after an investigation campaign or based on interpretation of sources, or evidenced by a different activity (such as: preparatory works for urban construction, rescue archaeology and similar) and is carried out according with specific authorisations provided by a competent authority. A specific identifier for each archaeological excavation is usually assigned by the same authority. The set of activities is not limited to matter removals but also comprises siblings activities, happening throughout the whole process, intended for observation and/or consolidation of the excavated strata. The archaeological excavation is usually under the responsibility of a coordinator, officially designated, which is legally and scientifically responsible for all the activities carried out within each of the excavation process units and is also responsible for the documentation of the whole process.
