To summarize recent work on the FLAC specification, the document has been
adjusted in its new markdown format in order to achieve semantic similarity to
the original HTML rendition on the xiph.org site. In order to get the
structural data (such as the tables at the end of
https://xiph.org/flac/format.html) to fit in plain text RFC style, the tables
were dissected a bit to separate value lists from structural lists. In this way
the subcomponents and defined in their own sections instead of the prior
strategy of detailing lists and pseudocode within large tables. For instance
see the original rendition of the frame header documentation from
https://xiph.org/flac/format.html#frame_header compared to the dissected
version which gives the subcomponents their own subsequent sections at
https://github.com/privatezero/flac_markdown/blob/7a5c21d49d1fda89609ffa9edfca2447c7ca3c5e/flac.md#frame_header.
Splitting out the subcomponents into their own sections also gives space to be
more explicate in defining them, such as
https://github.com/privatezero/flac_markdown/commit/3aaa5f293102018bd7c41409e79e36f510557d96.
Andrew noticed that there are some issues with managing section titles that
contain underscores and getting internal sectional citations to work. For
instance (#frame-header) will link to `FRAME HEADER` (space) but not
`FRAME_HEADER` (underscore). Is there any reason not to swap the all-caps,
underscored component names to tilde-quoted, all caps name with spaces rather
than underscores?
For convenience, here is a rendering of the plain text RFC output of git-master
of the FLAC format repository:
https://gist.github.com/dericed/2639d0eed5e064b4dec1399bc8716833.
I suggest reviews of the current markdown from those familiar with the
historical FLAC format specification so that we ensure that the current work is
the same in meaning to the original html version of the specification.
Best Regards,
Dave Rice
