Choice of file format

[badele]

I'm trying to design a new flat file format, unlike CSV, with the aim of making it viewable without a specific reader.

The features are:

• text -> cfwf
• cfwf -> to an object of array type (currently deno and JavaScript are supported)
• Ability to add multiple tables in the same file
• Ability to add a title in ASCII art mode
• Ability to add a subtitle for each table
• Ability to add a comment for each table
• Ability to add metadata for each table

I'm torn between three file formats:

• Format A: Metadata is mostly in plain text
• Format B: Metadata is in YAML format in each tables section
• Format C: Metadata is in YAML format at end of the file

I must admit that I lean towards Format C because it seems more flexible and readeable (in case the file format evolves), but it has a slight drawback as it appears slightly less visible.

Feel free to share your feedback.

Format A

Metadata are calculated from markers, can be difficult to evolve over time
