With the advent of the so-called Web 2.0 technologies, web resources became the primary platform for internal and external collaboration, knowledge exchange, and self-publication. Many of these services cannot be fully preserved by solely relying on client-side technologies like crawlers. In particular, their dynamic and reactive character will be lost by generating static snapshots. In this article, we develop concepts and describe infrastructure built on emulation to address the problem of retiring obsolete web service infrastructure while keeping the service long-term accessible and usable. We show the practicability of this approach by the example of three use-cases from academic projects.
