5. On File Formats
Total comment counts : 12
Summary
The article discusses the considerations involved in designing file formats, emphasizing that different formats serve various goals and that existing solutions may often suffice. If a custom format is needed, especially for specific use cases, it’s important to minimize parsing errors and ensure clarity in human-editable data. The author suggests using a “chunked” format, which allows for flexibility and compatibility, enabling future tools to read different parts of files efficiently. Including a version field is recommended to prevent issues down the line, even if changes seem unnecessary initially.
Top 1 Comment Summary
The article emphasizes that existing file formats often do not follow recommended rules for effective design. While human-readable formats should be simple, binary formats are preferable for complex numeric data. Chunking aids in structuring and parsing but does not ensure reordering or compatibility unless designed for it, as seen in PNG. It also advises considering existing formats as containers to ease the development of new file formats, recommending specially designed options like sBOX and CBOR-labeled data tags for this purpose.
