Scraper - A Composable Taskflow Framework

Scraper is a framework which enables flow-based programming in a declarative way. It is based on two main components: the core which translates the declarative description into a format that is understood by the framework, and the actual nodes which can be composed to construct a workflow.

The main goal of this framework is to facilitate reuse of code (nodes) and help managing control flow of programs in an easy way (control flow graph).

A recent Java version is recommended.

For more information, visit the quick start guide if you want to use the framework or the developer's quick start guide if you want to contribute to the project.

There is also a quick overview over existing features.
