Olabusayo Kilo updated DAFFODIL-2941:
-------------------------------------
Priority: Minor (was: Major)
> Implement DFDL experimental offset/pointer feature
> --------------------------------------------------
>
> Key: DAFFODIL-2941
> URL: https://issues.apache.org/jira/browse/DAFFODIL-2941
> Project: Daffodil
> Issue Type: New Feature
> Components: Back End, Front End
> Affects Versions: 3.9.0
> Reporter: Mike Beckerle
> Priority: Minor
>
> A major feature of DFDL slated for v2.0 of the spec is the offset pointer
> feature described in this DFDL Workgroup document:
> [https://github.com/OpenGridForum/DFDL/blob/master/docs/current/gwde-dfdl-experience-8-experimental-indirection.docx]
> This needs prototyping/implementation in Daffodil as a way of thoroughly
> vetting the feature proposal and getting clarifications where it is unclear,
> as well as providing a 2nd implementation which is needed for the standards
> process.
> (note: At one time it was thought that this indirection feature might be
> sufficient to allow DFDL to describe some complex pointer/offset based data
> formats like TIFF image format. That problem seems to still be out of reach
> due to the "linked-list of unknown length" situation in that format. This
> capability is not present in the proposed DFDL extension.)
