Lara, All releases of Daffodil have been converging towards implementing that specification. That specification is a cleanup of the prior "draft spec" version.
Of the DFDL implementations that exist, Daffodil is closest to fully implementing that specification. Version 3.3.0 is the newest and most complete. That said. there are some features of that spec that are still unimplemented, and there are bugs in some features. This page is about unimplemented features https://daffodil.apache.org/unsupported/ Our bugs (and tickets for features not yet implemented) are here: https://issues.apache.org/jira/projects/DAFFODIL/issues I know that this isn't the cleanest answer, but it is what we have. In an ideal world we'd have an HTML version of the DFDL spec which has warning highlighting around the DFDL features that are not supported or which have known bugs. Maybe someday someone will contribute that. -mike On Wed, May 11, 2022 at 11:48 AM Lara Blatchford < lara.blatchf...@nteligen.com> wrote: > Hello – can someone tell me what release of Daffodil supports DFDL > specification version GFD-P-R.240 from October 2020? > > > > Is there a document somewhere that associates specification versions with > the release of Daffodil that supports that version? > > > > Thanks, > > Lara >
