The Documentation Working Group focuses on the critical task of documenting tangible cultural heritage for conservation. The group aims to enhance the documentation of cultural heritage through the use of advanced and emerging technologies. These technologies not only create new ways of documenting, but can also enhance existing documentary archives. The principal areas of activity are in the fields of 2D and 3D digital imaging, and in the field of semantics and data interoperability. Three main objectives are essentially: to develop and promote digital technology for documenting artifacts for conservation; to foster co-operation, system interoperability and the free exchange of data between institutions; and to promote the development and use of new or advanced techniques in imaging (multispectral imaging/HDR/3D scanning, etc.).
