Within the Prêt-à-LLOD project, five major challenges when working with linguistic resources are addressed (cf. Fig. 1): ● Discovery of resources ● Data management and licensing ● Transformation of heterogeneous resources ● Interlinking resources ● Embedding resources and algorithms into complex workflows This short report accompanies the Prêt-à-LLOD software deliverable D3.3 1 “Resource Transformation Software”. It is meant to provide a quick overview of the motivation, software architecture and its basic functionalities. It also serves as a pointer to the repositories, where both the code and more detailed user guidelines are available.
