15. Leveraging Open Standards It leverages open and extensible development platform of OKI and FEDORA digital repository to facilitate collaborative open source development.

16. Goals for VUE 1. In support of teaching, provide faculty with a flexible, visual tool for semantically structuring and creating pathways through digital materials in a manner most consistent with the ideas and concepts that they must communicate to their students. 1. In support of teaching, provide faculty with a flexible, visual tool for semantically structuring and creating pathways through digital materials in a manner most consistent with the ideas and concepts that they must communicate to their students. 2. In support of active learning, provide students with a flexible tool for manipulating and extending existing instructional presentations (concept/content maps) in support of personal reflection on course topics as well as support for the creation and communication of new, personally meaningful concept/content maps. 3. Extend the value of FEDORA-based digital libraries and their collections by providing a flexible, visual tool for viewing and organizing digital content in pursuit of individual learning and research goals. 4. Leverage OKI technical standards to enable the sharing, distribution and integration of this new educational tool in educational environments and systems beyond Tufts University.
