title: How Long Can We Build It? Ensuring Usability of a Scientific Code Base
abstract: Software and in particular source code became an important component of scientific publications and henceforth is now subject of research data management.&nbsp; Maintaining source code such that it remains a usable and a valuable scientific contribution is and remains a huge task. Not all code contributions can be actively maintained forever. Eventually, there will be a significant backlog of legacy source-code. In this article we analyse the requirements for applying the concept of long-term reusability to source code. We use simple case study to identify gaps and provide a technical infrastructure based on emulator to support automated builds of historic software in form of source code.
