title: Management and Orchestration of Distributed Data Sources to Simplify Access to Emulation-as-a-Service
creators: Thomas Liebetraut Klaus Rechert
abstract: Emulation-as-a-Service makes emulation widely available for non-experts and thus, emulation could prove valuable as a tool in digital preservation workflows. Providing these emulation services to access preserved and archived digital objects poses further challenges to data management. Digital artifacts are usually stored and maintained in dedicated repositories and object owners want to or are required to stay in control over their intellectual property.
  
  In this paper we propose a distributed storage and data access model that ensures that the user stays in control over his digital objects by simultaneously providing efficient data transport and support for (space) efficient management of user modifications. Finally, a mechanism for orchestration of both storage and emulation services to re-enact a single pre-defined setup is presented.
