Over the years, the DH Research&Infrastructure team has developed hundreds of specialized applications. While initially many of them were bespoke solutions for individual projects, some of these applications developed into more generalized solutions, which can be applied for a whole class of tasks pertaining to a specific type of data. These so-called “core software & services” are used in numerous projects and are continuously developed further. As opposed to project-specific applications, for core services there is a warranty for long-term support.
