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.
