Immer wieder tauchen sie in unerwartet weit entfernten Siedlungen auf. Die dazwischen liegende Region bietet sich deshalb dafür an, die wirtschaftlichen Einflussbereiche beider Brüche zu rekonstruieren.
Durch die Dokumentation möglichst aller Mühlen in diesem Gebiet gelingen unter Hinzuziehung petrographischer Analysen eine Charakterisierung dieser bedeutenden Brüche und die Identifizierung weiterer bisher unbekannter Quellen.

L'étude est principalement axée sur les meules rotatives antiques conservées dans les collections du Musée gallo-romain de Tongres et dont les pièces ont été mises au jour dans la province du Limbourg correspondant à la partie centrale de la cité des Tongres, la civitas Tungrorum. Ces collections ont été enrichies par les découvertes faites lors de plusieurs opérations d'archéologie urbaine préventive et programmée, effectuées à Tongeren durant les dernières décennies. Le corpus d'étude publié comprend plus de 80 meules limbourgoises (entières ou fracturées, majoritairement rotatives) reparties sur un grand intervalle chronologique qui s'échelonnant de l'Age du Fer jusqu'au Temps Modernes. De nouvelles methodes de recherche ainsi qu'une approche interdisciplinaire ont permis une étude approfondie de ce corpus de meules et ont conduit à de nouvelles perceptions quant à l'origine des matières premières, des voies de transport, les outils utilisés pour le façonnage et le r(habillage) des meules, les techniques de taille, l'habillage et le décor du corpus de meules analysé. L'ouvrage offre également un inventaire élaboré, une description complète des objets et la détermination des origines géographiques et géologiques des matériaux au moyen d'analyses pétrographiques et/ou géochimiques. Les résultats sont replacés dans le cadre général des habitudes alimentaires et agricoles du chef-lieu de la cité des Tungri et de ses régions avoisinantes.

Knowledge Based Optimal Recommendation of Spatial Technologies for Documentation of Buildings.

Spatial and spectral recording of material cultural heritage is an interdisciplinary task which r... more Spatial and spectral recording of material cultural heritage is an interdisciplinary task which requires mutual understanding and agreement for achieving a common goal. This task is often tedious, time consuming and not recorded. COSCHKR captures the core knowledge of these interdisciplinary interactions and logically structures it. COSCHKR is an ontology based knowledge representation that represents the experts’ knowledge explicitly so that it can be reasoned to recommend technology(ies) and their technical solutions. In this paper we discuss how technologies are recommended based on their demands from the cultural heritage application especially focusing on large objects. We also demonstrate how other technologies that are suitable for recording smaller objects are ignored while recommending technologies such as photogrammetry and laser scanning suitable for large objects.

To achieve common goals it was of utmost importance to have a common understanding of these diverse activities and disciplines. Work on the COSCH Knowledge Representation, or COSCHKR, was undertaken to develop a common semantic base representing different disciplines and to facilitate communication within the Action. The COSCHKR is an ontology-based inference model, guided by inference rules that provide a semantic bridge between various interdisciplinary activities involved in non-invasive technical documentation of material cultural heritage. The model is intended to support humanities experts by recommending optimal spatial and spectral techniques. The model may also be used by technology experts to compare their own solutions with the ones recommended through COSCHKR, and to understand why they may differ.
In this chapter we present the methods adopted for designing the COSCHKR and the steps in the development of the inference model. The difficulties in maintaining a common level of understanding within the diverse disciplines during the knowledge acquisition process are discussed. We present mechanisms and methods of information collection, its structuring, and aligning, to formulate different axioms and theorems within the model. The design and development of COSCHKR was based on an iterative procedure where the gathered knowledge was first verified with the group of experts before it was processed. This verification mechanism was important for the reliability of the model, ensuring technical consistency. This chapter highlights the importance of these iterative mechanisms in the validation of knowledge gathered and then information populated inside the knowledge base.

Situated in Burgundy, France, Germolles is the best preserved residence of the Dukes of Burgundy and was listed as a monument of national importance in 1989.
The medieval wall decoration of the Château de Germolles was rediscovered under the nineteenth-century plasters during World War II. Medieval accounts of the château provide a detailed list of the materials acquired to make the mural decoration, but this list is incongruous when compared with the current appearance of the paintings. The discrepancy between the archival and material evidence, and also the need to understand the complexity of the painting technique used were the main motivations for undertaking the case study described in this chapter. Imaging alongside more traditional examination techniques were utilized to record and document the mural decoration. The objectives of the case study were to distinguish the original materials from those applied during restoration, identify those materials, and correlate them with the archives. We also tried to understand the medieval painting techniques used and assess the condition of the paintings and stabilization requirements. Finally we aimed to find a sustainable solution for the management of the various types of data collected. Various techniques and investigations offered valuable insights into the materials and the painting technique used. To improve visitor experience, based on the information gained in the course of this study, a 3D virtual representation of the original decoration is currently proposed for display to the public visiting the Château de Germolles.

This chapter charts the interdisciplinary discussion towards a common understanding of terminologies used in CH. It is a discussion that recognizes critical differences or common misuse, and aims to contribute to a shared understanding that may be useful for all knowledge domains in the field.

Both objects match up with a typology which was developed on the basis of numerous Late Iron Age rotary querns discovered in Germany: The types of the upper and lower stone are characteristic for the production in quarries located in the Eifel. Using a combination of geochemical discrimination, cluster-, and discriminant analyses, both rotary querns could be allocated exactly to their quarries at the Bellerberg volcano near Mayen in the East Eifel area. However, being the only Eifel lava rotary querns known in Bohemia their occurrence is not sufficient to assume a regular and continuous exchange between Bohemia and the Eifel quarries in Late Iron Age times.

In many cases, a lack of understanding of transdisciplinary semantics slows this process down. The end users who are mostly humanities experts lack the technical knowledge of spatial and spectral recording and could therefore demand more than what is actually required or sufficient for the intended CH application. The negotiations between technical experts and the end users are a tedious process. We present a semantic-based decision support system, COSCH KR , that employs reasoning and recommends optimal recording technology(ies) according to the application requirements of the recorded and processed data. COSCH KR is an ontology-based knowledge model that implies the development of semantic technologies within the Semantic Web framework. It represents formalized knowledge of the disciplines involved in the...
