Accuracy, artefact, feature, precision, reconstruction, resolution, texture, uncertainty are words central to many discussions of the documentation of cultural heritage. This terminology, whilst broadly understood across the disciplines, is often misunderstood due to its specific use in particular cases. An interdisciplinary dialogue conducted over a period of years and comprising experts in a range of fields-art history, colour science, engineering, semantics, mathematics, cultural heritage, museum studies, and others-has yielded a challenging discussion document that considers the thorny issue of a shared understanding of a set of keywords. On occasion our perceived shared language is not shared at all but reveals-at times through subtle nuance, and yet at times through gaping chasm-the disciplinary subjectivities we hold unbeknownst to ourselves. Mutual understanding of some of these key terms is central to any newly engaged, participatory transdisciplinary endeavour that seeks to develop critical methods for the documentation, analysis, preservation, and sharing of cultural heritage objects outside the traditional disciplinary silos. This chapter charts the interdisciplinary discussion towards a common understanding of terminologies used in cultural heritage. 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. The chapter summarizes the work of a number of Think Tanks conducted by Early Career Investigators participating in the COSCH network.
