EulerView: article organisation within the ACM classification

EulerView is a resource management tool which supports operations, such as intersection, on categories. We relate EulerView displays to sets of paths in the transitive closure of the directed dual graph of an Euler diagram, and provide methods for transforming hierarchies with symbolic links into an EulerView display. Linking the display directly to the file system enabled the export of both the directory structure and resource placement which enables users to build small manageable views of their categorisation structure within which to place resources and then export this onto the larger file system. Using the transformation methods developed, we consider the importation of ACM classification into EulerView, enabling users to categorise and store resources such as articles within the imported ACM classification. EulerView is tailored to be appropriate for the ACM CCS application, and new techniques for focus and navigation within EulerView are developed.
