  @AlanSill I'm aware of DFDL! I actually largely use Kaitai, and I was mostly just saying how much *fun* I have going into them. The rare toot where I was being earnest but using language that sounds sarcastic!

  @powersoffour There may already be published DFDL descriptions for many formats of interest. See https://en.wikipedia.org/wiki/Data_Format_Description_Language?wprov=sfti1 and https://github.com/DFDLSchemas for starting points.

    Data Format Description Language
    
    Data Format Description Language (DFDL, often pronounced daff-o-dil) is a modeling language for describing general text and binary data in a standard way. It was published as an Open Grid Forum Recommendation in February 2021, and in April 2024 was published as an ISO standard. A DFDL model or schema allows any text or binary data to be read (or "parsed") from its native format and to be presented as an instance of an information set. (An information set is a logical representation of the data contents, independent of the physical format. For example, two records could be in different formats, because one has fixed-length fields and the other uses delimiters, but they could contain exactly the same data, and would both be represented by the same information set). The same DFDL schema also allows data to be taken from an instance of an information set and written out (or "serialized") to its native format. DFDL is descriptive and not prescriptive. DFDL is not a data format, nor does it impose the use of any particular data format. Instead it provides a standard way of describing many different kinds of data formats. This approach...
