OSBL stands for Open Source Business Library. Its goal is to provide an open solution that efficiently supports work processes in a business environment. There are many Open Source components on the market, some of them of a very high quality, that provide solutions for individual aspects of this. However, individually they fall short in achieving a solution; the decisive factor is their integration into a coherent whole. The purpose of the OSBL is to achieve this integration. It combines several well-known Open Source Java components in a way that allows for an easy and effective implementation of process-driven web applications.
