## 1. What is UIMA Ruta?

Apache UIMA Ruta™ is a rule-based script language supported by Eclipse-based tooling. The language is designed to enable rapid development of text processing applications within Apache UIMA™. A special focus lies on the intuitive and flexible domain specific language for defining patterns of annotations. The Eclipse-based tooling for Ruta, called the Ruta Workbench, was created to support the user and to facilitate every step when writing Ruta rules. Both the Ruta rule language and the Ruta Workbench integrate smoothly with Apache UIMA.

## 2. Major Changes in this Release

This release provides compatibility to UIMA v3. An upgrade from UIMA Ruta v2 to this version requires also an update to UIMA v3 of the overall application or Eclipse installation. Please refer to the UIMA v3 user's guide for detailed information: https://uima.apache.org/d/uimaj-3.0.0/version_3_users_guide.html
