I t is easy to The Konstanz Information Miner is a modular environment, extend through an open API and a data abstraction fr ame work, which allows for new nodes to be quickly added in a which enables easy visual assembly and interactive execution well-defin ed way. of a data pipeline. It is designed as a teaching, research and collaboration platform, which enables simple integration of In this paper - which is based on an earlier publication [1] new algorithms and tools as well as data manipulation or concentrating on KNIME 1.3 - we describe the internals visuali zation methods in the form of new modules or nodes. of KNIME in more detail with emphasis on the new fea In this paper we describe some of the design aspects of the tures in KNIME 2.0. More information as well as down underlying archi tecture, briefl y sketch how new nodes can loads can be found at http: //www .knime . org.
