Research Studio Digital Memory Engineering (RS-DME)


In work package 2 of the Research Studio Digital Memory Engineering Project, the University of Vienna investigates the long-term digital preservation of data created by Web 2.0 applications and Wikis in particular.

What is called Web 2.0 today marks an evolutionary step in the World Wide Web towards more user involvement and interactivity. It can best be tagged with the words connect, communicate and collaborate. Wikis, like Wikipedia, follow these Web 2.0 principles in many ways. They invite any Web user to actively participate in the ongoing process of creation and collaboration, connecting individuals and their knowledge.

Wikis become increasingly popular in both, the corporate and the private sector. Reasons for this include: (1) they are easy to use, (2) they embrace collaborative content creation and exchange, and (3) they are free and open source. Wikis are easy and cheap to use and run and show low total costs of ownership (TCO). These characteristics render Wikis ideal tools for common tasks in corporate environments like e.g., collaborative project documentation or knowledge management tasks. Naturally, these data stored in corporate but also in public Wikis is a good candidate for digital long term preservation.

Yet, current archiving methods simply store the HTML representation of Wiki articles - that is what you see in your web browser - in its current version at the time of archiving. This simple approach leaves out many of the core elements of Wikis: the source code of the articles, the content history, links to the contributing users, embedded resources, etc. Little research has been done in the area of digital preservation of Web 2.0 application data. The objective of work package 2 is to investigate how the highly dynamic and interlinked data of Wikis can best be preserved in the long-term.

The University of Vienna develops a tool based on semantic Web technologies that preserves data stored in public or corporate Wikis in the long-term, including embedded and linked resources like text documents, images or videos.
