  1. Representation of Complex Objects Collection Development & Interpretive Activities & Preserving Virtual Worlds • Henry Lowood • Green Library • Stanford University Jerome McDonough Graduate School of Library & Information Science University of Illinois at Urbana Champaign

  2. PVW Project Goals • To help develop mechanisms and methods for preserving digital games and interactive fiction by • Investigating preservation issues through a series of archiving case studies; • Developing basic standards for metadata and content representation; • Archiving key representative content; and • Building community awareness of issues.

  3. Project Outline • Phase I: Background research on preserving interactive behavior and case set definition • Phase II: Development of schema/ontologies necessary for representation and contextual information and recommendations for best practice in use of wrappers • Phase III: Implementation and testing via ingest of content at Stanford and UIUC.

  4. You are in a maze of twisty little passages, all alike.
