Apache Daffodil is an open-source implementation of the DFDL specification that uses DFDL data descriptions to parse fixed format data into an infoset. This infoset is commonly converted into XML or JSON to enable the use of well-established XML or JSON technologies and libraries to consume, inspect, and manipulate fixed format data in existing solutions. Daffodil is also capable of serializing or "unparsing" data back to the original data format. The DFDL infoset can also be converted directly to/from the data structures carried by data processing frameworks so as to bypass any XML/JSON overheads.
