Web Services are being adapted into the workflows of many Document Image Analysis researchers. However, so far, there is no common platform for providing access to algorithms in the community. DIVAServices aims to become this by providing a platform that is open to the whole community to provide their own methods as Web Services. In this paper we present updates and enhancements made to the existing DIVAServices platform. This includes a new computational backend, a revamped execution workflow based on asynchronous communication, and the possibility for methods to specify their outputs. Furthermore, we discuss the importance of an ecosystem for such platforms. We argue that only providing a RESTful API is not enough. Users need tools and services around the framework that support them in adapting the Web Services and we introduce some of the tools that we built around DIVAServices.
