Project Notes for the Defense Virtual Information Architecture

• Defense Technical Information Center
• Defense Advanced Research Projects Agency
• Corporation for National Research Initiatives

• Put in place new ways to manage new types of digital information. Still and moving images, sound, as well as text, have been implemented.
• Identify the metadata required for long-term management of digital objects -- not just for resource discovery but also for protection of intellectual property and preservation across changing technologies.
• Use standard Internet browsers.
• Use Uniform Resource Names (Handle System) instead of URLs (Uniform Resource Locators) for long-term management of digital information objects.
• Use applicable standards and best practices -- CORBA, MARC, and AACR2.
• Implement advanced commercial search engine technology (Verity).
• Serve as a testbed for DARPA-funded research in computer architectures using DTIC data.

• Metadata for DTIC technical report citations mapped to MARC-like display.
• Metadata for still image, sound, and moving image materials created according to AACR2/MARC standards.
• DTIC technical reports viewable as full text in PDF.
• Still  images in GIF and JPEG formats.
• Sound files for music and oral history excerpts playable in Real Audio and WAV formats.
• Moving image files in Real Media and MPEG formats.
