The challenges involved in assuring the longevity and validity of heritage science data, and access to that data, require that all scientific data terminology and experimental procedures are not proprietary and have a common meaning across heritage institutions. While the temptation to create a new set of thesauri and definitions is great, it merely exacerbates the "siloed" impact that tends to separate rather than aggregate colleagues and data. Using IIIF and the Mirador viewer to integrate scientific and scholarly data about heritage objects, it became apparent when attempting to create a cohesive structure that terms in common use amongst one group of users were not necessarily familiar to the others. Therefore, easily accessed but rigorous controls on terms needed to be put into effect, with preference deliberately given to reusing existing resources.
