## 1. What is the UIMA-Addons package?

The Apache UIMA addons package is a collection of additional components for the base UIMA release. The add-on package contains annotator components developed for Apache UIMA. The add-on package fits the Apache UIMA directory structure and adds a directory called "addons lib" that contains the following annotator components:

- DictionaryAnnotator
- RegularExpressionAnnotator
- Tagger
- WhitespaceTokenizer
- Bean Scripting Framework (BSF) BSFAnnotator
- ConceptMapper
- ConfigurableFeatureExtractor
- Lucas
- OpenCalaisAnnotator
- SnowballAnnotator

Additionally the package contains some components to package annotators and for accessing annotators as simple REST service. These are:

- PearPackagingAntTask
- SimpleServer

There is an addon to the base UIMA:

- FsVariables

Each component has a separate LICENSE and NOTICE files; some also have Readme and other documentation (in docs/). Documentation is also available on the UIMA website, in the Sandbox area.
