University of Maryland professor (and Hooblogger) Matthew Kirschenbaum points to Acid-Free Bits, a guideline for ensuring the preservation of digital-only works of literature. The document is fascinating and ties together neatly some threads of investigation around web standards (don’t code with proprietary extensions, separate content from presentation using XML, validate code), programming best practices (consolidate code, supply comments, document early and often, prefer community-directed systems), copyright concerns (allow and encourage duplication and republication), and library science (maintain metadata and bibliographic information). Cool stuff.
