The Daffodil framework may be relevant.

Thanks a lot, I'll have a look through the resources. I think that's exactly what I'm looking for.

Working on a parser / mutator framework that will support a lot of different formats. Using NITF to work through some of the design. It's a lot higher level of just "can we chunk out this feature" rather than understanding how every field is going to affect rendering. Right now I'm just making sure all my structures are implemented correctly.
