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.

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.

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