Renumbering figures after adding diagram to filters section This document was created to provide an insight in and review on the technical infrastructure in use for the Narrow Band Multi-Spectral Imaging (NBMSI) system of the 3Pi Project (Book Heritage Lab, Faculty of Theology and Religious Studies, KU Leuven), operated in the Imaging Lab of the KU Leuven Libraries. At KU Leuven this narrow band multi-spectral imaging infrastructure has been obtained and is being operated within the framework of this 3Pi Project (Diagnosis of Papyrus-Paper-Parchment manuscripts through advanced Imaging, AKUL/17/001, FWO: I009918N, Mid-scale Research Infrastructure). This NBMSI system was created by R.B. Toth and Associates LLC, in association with Equipose Imaging LLC and Phase One A/S and their local partners; the acquisition software of the system is Spectral XV. The technical infrastructure acquired by the 3Pi Project is part of the Faculty of Theology and Religious Studies. Promotor-spokesman is prof. dr. Johan Leemans; coordinator is prof. dr. Lieve Watteeuw (Head Book Heritage Lab); implementation of the NBMSI system by Bruno Vandermeulen (Head Imaging Lab) & Hendrik Hameeuw (Advanced Imaging, Imaging Lab). The NBMSI system at KU Leuven consists of: Phase one XF IQ4150MP AchromaticCamera System (light sensor) Schneider Kreuznach 120mm LS f/4.0 Macro (lens) Filter wheel with band pass and long pass filters 2 Eureka light panels TX Transmitting Module Kaiser rePRO RSP (copystand) Spectral XV software

The DOI for all version of this standard is10.5281/zenodo.3607363 Reasons for update from version 1 (https://doi.org/10.5281/zenodo.3607364): ● All NBMSI metadata entries received an unique ID. ● Extra insight into the management and handling of the metadata have been added. ● The update provides better tools to allow machine readability of the documented metadata. ● Examples of implementation strings into the EXIF Image Description field. ● Small clarifications and corrections. A. The objective of the KU Leuven NBMSI Metadata Standard, developed within the framework of the 3Pi project,is to define the required or relevant metadata elements and their parameters for image captures created with a photographic Narrow Band Multi-Spectral Imaging (NBMSI) technology. The determined and selected metadata fields provide information necessary to outline the creation environment and technical infrastructure used in the production of the images. These are not standard included in the basic EXIF or IPTC fields embedded in the image derived from the camera system itself. As such this is metadata pertaining to the image dataset and not to the object being imaged. The KU Leuven NBMSI Metadata Standard is intended to provide definitions and conventions, allowing users to access documentation for images stemming from a common set of terminology. This will therefore provide a level of consistency for the metadata information. Therefore, the primary functions of this document are: Providing users of the images with information about the creation environment of narrow band multi-spectral images. Defining standard metadata fields that can be embedded to a multitude of images for consistency and clarity. Outlining the values of these standardized metadata fields; how to measure and enter them. Allowing independent and long-term interpretation of the images. B. The scope of this standard is in the first place aimed at providing coverage to any objects that may be imaged by the narrow band multi-spectral imaging infrastructure deployed by the Imaging Lab at KU Leuven Libraries. This includes the collection held by the University Libraries, as well as collections brought in by external institutions or researchers. Secondly, the standard has also been constructed in the interest of having usability for other institutions, using similar narrow band multi-spectral imaging technology, inside or outside of KU Leuven. C. Related Standards: This standard was developed with direct reference to the Archimedes Palimpsest Metadata Standard. The Archimedes Palimpsest Metadata Standard originally draws from such standards including: Dublin Core Metadata Initiative Element Set (ISO Standard 15836) Content Standard for Digital Geospatial Data (FGDS-STD-001-1998) Art Museum Image Consortium (AMICO) &nbsp

When heritage objects are being transformed into digital representations, the loss of information is inevitable. The challenge lies in developing integrated systems able to minimize this loss and bring together as many different kinds of recordable characteristics as possible of one and the same object. This contribution presents an approach that combines the detection of colour, surface shape and the reflective characteristics of surfaces by using a selection of IR, Red, Green, Blue and UV light spectra and applying them on 3D models. A multispectral, multi-directional, portable and dome-shaped recording tool has been developed to this end. With the associated software, virtual relighting and enhancements can be applied in an interactive manner based on the principles of photometric stereo: this allows alternating in real time between computations with IR, R, G, B, and UV light spectra. Throughout the testing phases, this non-invasive registration and documentation technique has been applied to monitor and study a vast number of heritage objects, varying from 19th c. BCE Egyptian inscribed clay figurines to medieval illuminations. ispartof: pages:163-192 ispartof: Lights On … Cultural Heritage and Museums! pages:163-192 ispartof: Lights On … Cultural Heritage and Museums! location:Porto date:20 Jul - 22 Jul 2015 status: published
