A converter pipeline enables converting and normalizing data that has been retrieved from remote repositories by sequentially changing that data from one format to another.
You can write a Java converter that you can add to the conversion pipeline (also known as the "converter pipeline") used by Watson Explorer Engine. A conversion pipeline also provides a flexible framework for adding converters that augment input data and metadata during the conversion process. Common augmentation tasks include entity extraction and sentiment analysis.
Watson Explorer Engine provides a sample Java converter template project that is available on GitHub at https://github.com/IBM-Watson/wex-engine-java-converter-template. Additionally, this template describes how to use, build, and deploy the Java converter template project.
