Sqlite has some good documentation. Their explanation of the file format is a good example: https://www.sqlite.org/fileformat.html https://www.sqlite.org/fileformat.html Much better than other file format docs I've read, covers almost all the corner cases well, broken up into logical sections, uses tables for data formats when that makes sense, etc.
