Just an update on our process. As you know, as per https://ogf.org/documents/GFD.152.pdf we can publish any errata as needed with a suitable annotation and header update but without a document number update, if the changes fall under the categories mentioned in section 8 of that document. As it says there, "This errata process is not intended to be a mechanism for obsoleting prior versions of a document. If substantial updates are needed, a new document should be created and brought

through the complete editorial review process." The process is normally supervised bye the OGF Editor. Due to the recent untimely passing of Greg Newby, which we all deeply mourn, the Editor position will need to be filled by someone else; meanwhile the GFSG can supervise this process. The quickest thing to do would be to select a path for the DFDL update on the OGF side and get started producing this.

We are up for renewal on our OGF ISO PAS status. I don't anticipate any difficulties. The application is out for JTC 1 member ballot, which closes 12/23/2025. The document you found and linked on the DFDL GitHub, https://jtc1info.org/wp-content/uploads/2022/01/SD-9-Guide-to-the-Transposition-of-PAS-2021.pdf is the right one, so please let me know any thoughts you may have after reading through that as well. Let us know of any assistance you need or questions we can help resolve thorough our ISO contacts as you proceed in this process.

Good morning Mike,

Thanks for the question. Let us look into this and get back to you about the process for updates. As I recall, more interactivity with the relevant ISO working group is expected for ongoing updates compared to the initial submission.

Alan,

When DFDL was first submitted as a PAS standard to ISO, besides the OGF DFDL document itself, I believe there was additional material also that was part of making up the overall submission package.

I'm a bit unclear on what materials are part of OGF being accepted as a PAS submitter, and where that material ends, versus which materials accompanied the specific PAS submission of DFDL. I.e., which materials would also need to be updated if a revised DFDL version were submitted.

Can you advise on what these additional documents would be to make up a complete submission "package"?

An update to DFDL is quite possibly in the works, not imminently, but in a year or so, but I am retiring at the end of 2025 so will be less active going forward. I want to set the stage on what all is involved in creating an updated DFDL spec., beyond just the spec itself, for those still working on it.

Thank you for any info
