Apache Daffodil (incubating)

Introduction

Apache Daffodil (incubating) is the open source implementation of the Data Format Description Language (DFDL), a specification created by the Open Grid Forum. DFDL is capable of describing many data formats, including textual and binary, commercial record-oriented, scientific and numeric, modern and legacy, and many industry standards. It leverages XML technology and concepts, using a subset of W3C XML schema type system and annotations to describe such data. Daffodil uses this description to parse data into an infoset represented as XML or JSON, easily capable of ingestion, validation, and transformation.
