The Apache Daffodil (incubating) community is pleased to announce the
release of version 3.0.0.

Notable changes in this release include SAX support, streaming, reduced
memory usage, improved diagnostics, and bug fixes.

Detailed release notes and downloads are available at:

https://daffodil.apache.org/releases/3.0.0/

Daffodil is an open source implementation of the Data Format
Description Language (DFDL) specification that uses DFDL schemas to
parse fixed format data into an infoset, which is most commonly
represented as either XML or JSON. This allows 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 the reverse by serializing or "unparsing"
an XML or JSON infoset back to the original data format.

Apache Daffodil is an effort undergoing incubation at The Apache
Software Foundation (ASF), sponsored by the Apache Incubator PMC.
Incubation is required of all newly accepted projects until a further
review indicates that the infrastructure, communications, and decision
making process have stabilized in a manner consistent with other
successful ASF projects. While incubation status is not necessarily a
reflection of the completeness or stability of the code, it does
indicate that the project has yet to be fully endorsed by the ASF.

Subject: [wg-all] New OGF document in public comment: DFDL 1.0
To: All WG <wg-all@ogf.org>

Dear OGF Community:

A new OGF document is now available for public comment.  Please consider reading it and providing your input.  Brief affirmations are very useful to demonstrate community input and support.  More detailed analysis is, of course, welcome.

• DFDL 1.0
  The document (Word and PDF) and issue tracker are online at: https://github.com/OpenGridForum/Editor/tree/main/DFDL%201.0%20(GFD%20240)
  This is a Recommendation Track document, with a 60-day public comment period.When published, it will obsolete GFD #s 174 and 207.

Abstract: This document provides a definition of astandard Data Format Description Language (DFDL). This language allows description of text,dense binary, and legacy data formats in a vendor-neutral declarative manner.DFDL is an extension to the XML Schema Description Language (XSD).
This is the first public comment period for which we are utilizing a new github-based workflow. Public comments may be submitted as "issues" via the github link above.
All contributions are subject to the OGF community guidelines as described in the OGF Intellectual Property Policy, online at https://www.ogf.org/ogf/doku.php/about/copyright.

ApacheCon 2020 was a virtual conference this year. Mike Beckerle gave a talk about DFDL/Daffodil entitled "Kill the Data Format Problem" a recording of which is available on youtube via this link:
https://s.apache.org/apachecon-2020-kill-the-data-format-problem.

The cybersecurity use case for DFDL is described starting at time 18:12, which explains how DFDL is used to address the "Bad-Data Denial-of-Service" threat.

The Apache Daffodil (incubating) community is pleased to announce the release of version 2.7.0.

Notable changes in this release are primarily the bug fixes, and a small set of useful new features from the DFDL specification.

The Apache Daffodil (incubating) community is pleased to announce the
release of version 2.5.0.

Notable changes in this release include user defined functions, BLOBs,
unordered sequences, 2GB+ files, and preparation for decreasing schema
compile time.

This release also improves interoperability with IBM DFDL and schemas
created for it, including all the schemas published at
https://github.com/DFDLSchemas.

The Apache Daffodil (incubating) community is pleased to announce the
release of version 2.4.0.

Notable changes in this release include improved DFDL schema
compatibility, new extensions, explicit length choices, better DFDL
schema validation, and many bug fixes.

This release improves interoperability with other DFDL implementations
by adding the needed DFDL features for support of commercial data
formats like EDIFACT, IBM4690TLOG, HL7, ISO8583, and data sets
created using COBOL.
