The document discusses Viewshare, a tool that allows users to dynamically interact with and understand digital cultural heritage collections by tapping into the temporal, locative, and categorical data within collections. Viewshare is used by librarians, archivists, curators, and researchers to better understand and expand access to their digital collections. It allows users to import, augment, build, and share visual displays and dynamic facets of collections for embedding and exposing as open data on websites.
