@mbeckerle I'm working on the logic to add queries similar to the Dynamic UDF capabilities which would allow a user to import the DFDL files. That will be a separate PR once this is merged. |
Requires Daffodil version 3.7.0 or higher. New format-daffodil module created Still uses absolute paths for the schemaFileURI. (which is cheating. Wouldn't work in a true distributed drill environment.) We have yet to work out how to enable Drill to provide access for DFDL schemas in XML form with include/import to be resolved. The input data stream is, however, being accessed in the proper Drill manner. Gunzip happened automatically. Nice. Note: Fix boxed Boolean vs. boolean problem. Don't use boxed primitives in Format config objects. Test show this works for data as complex as having nested repeating sub-records. These DFDL types are supported: - int - long - short - byte - boolean - double - float (does not work. Bug DAFFODIL-2367) - hexBinary - string apache#2835
