In recent decades, researchers of archaeological 3D digitalization found that the collection and archive of processing intermediate data are extremely tiresome tasks. They need large of man power and material resources, even though, mistakes can be raised and break the whole working chain. The traditional documentation of digitalization process is also a pending challenge, although, the ISO standard CIDOC-CRM (ISO 21127:2006) has been introduced to the archaeologists and museum professionals since years, but there are still some obvious gaps between practice and theory: (1) How to connect the discrete archaeologists, museums, CH research institutions, and the public? (2) How to ensure the integrity of whole digitalization process and simplify the process? (3) How to maximize the usability of the public digital objects in CH community? (4) How to long term preserve the huge amount of datasets? (5) How to present and disseminate the digital object to the public? This paper presents an operational and optimal infrastructure that realizes not only a distributed storage system, but also a content management system. This infrastructure works as a backbone of whole digitalization process, provides a complete solution suite for archaeologists, museum professionals, museum visitors, and IT technicians.

The development of a European market for digital cultural heritage assets is impeded by the lack of a suitable marketplace, i.e., a commonly accepted distributed exchange platform for digital assets. We have developed such a platform over the last two years, a centralized content management system with distributed storage capability and semantic query functionality. It supports the complete pipeline from data acquisition (photo, 3D scan) over processing (cleaning, hole filling) to interactive presentation, and allows collecting a complete process description (paradata) alongside. In this paper we present the components of the system and explain their interplay. Furthermore, we present and explain which functional components, from transactions to permission management, are needed to operate the system. Finally, we prove the suitability of the API and present a few software applications that use it.

A new technology is on the rise that allows the 3D-reconstruction of Cultural Heritage objects from image sequences taken by ordinary digital cameras. We describe the first experiments we made as early adopters in a community-funded research project whose goal is to develop it into a standard CH technology. The paper describes in detail a step-by-step procedure that can be reproduced using free tools by any CH professional. We also give a critical assessment of the workflow and describe several ideas for developing it further into an automatic procedure for 3D reconstruction from images.
