Gaps in the Standard: A Case Study of the Multi-Spectral Imaging Metadata Strategies at KU Leuven Libraries

Abstract This paper focuses on strategies for attaching technical infrastructural environmental metadata to narrow band multi-spectral images of cultural heritage objects. It also provides a review and analysis of previous projects involving multi-spectral images and their approaches to attaching metadata elements at the image level. This is followed by a detailed description of the strategies applied at KU Leuven Libraries to successfully and consistently attach standardized metadata that covers all areas of importance of the image capture. This aims to give users full understanding of the dataset and to allow interoperability and reproducibility. In addition to this, the documents created to ensure the consistency of the metadata entered and outline the specific infrastructure present at KU Leuven, are discussed. This includes the considerations of their implementation and the digitization workflows to produce metadata records.
