1 CRM archaeo Modelling Context, Stratigraphic Unit, Excavated Matter Center for Cultural Informatics, Institute of Computer Science Foundation for Research and Technology - Hellas Chryssoula Bekiari Dresden 6-11 September 2014 CIDOC 2014

2 Scope 2 Maximize interpretation capability after excavation or to continue excavation To Reason on excavation (goals). What is the archaeological question? Possible revision of knowledge after excavation Comparing previous excavations on same site (space) Enable all kinds of comprehensive statistical studies (“collective behaviour”)

6 6 Modelling stratigraphic units A2 Stratigraphic Deposit Unit comprises connected portions of terrain or other solid structure on, in, or under the surface of earth or seafloor exhibiting some homogeneity of structure or substance and completely bounded by surfaces or discontinuities in substance or structure with respect to other portions of the terrain or surfaces of objects/finds … may contain physical objects. … can be attributed to a single genesis event or process and have the potential to be observed. … is regarded to exist as long as a part of its matter is still in place with respect to a surrounding reference space A3 Stratigraphic Interface comprises coherent parts of the boundary surface of one or more stratigraphic units, which appears as result of a common genesis event or process. In particular it may be due to a removal process, which may be part of the genesis process of a Stratigraphic Unit or not... …confines (AP12) partly or completely the surface (A3 Stratigraphic Interface) of an A2 Stratigraphic Deposit Unit. One A3 Stratigraphic Interface may confine two or more A2 Stratigraphic Deposit Units.

12 A1 Excavation Process Unit …comprises activities of excavating in the sense of archaeology which are documented as a coherent set of actions of progressively recording and removing matter from a pre-specified location under specific rules. …would be terminated if significant discontinuities of substance or finds come to light, or if the activity should be interrupted due to external factors, such as end of a working day… the termination would be based on predefined physical specifications, … the boundaries of a maximal volume of matter intended to be excavated in one unit of excavation. …may intend to remove matter only within the boundaries of a particular stratigraphic unit, or it may follow a pre-declared spatial extent such as a trench. …may only uncover, clean or expose a structure or parts of it. …results in the production of a set of recorded (documentation) data …sufficient to provide researchers enough information regarding the consistence and spatial distribution of the excavated Segment of Matter and things and features embedded in it.. 12

15 Conclusions CRM Sci provides a comprehensive model for observation metadata regardless science and method. CRMArchaeo allows for a common representation of archaeological records and survey data, widely independent of local methodology. Still to be done: Specializations into analytical methods and reference data sets. Links: CRMarchaeo will be available soon at 15
