if you could pick a standard format for a purpose what would it be and why?
e.g. flac for lossless audio because…
(yes you can add new categories)
summary:
- photos .jxl
- open domain image data .exr
- videos .av1
- lossless audio .flac
- lossy audio .opus
- subtitles srt/ass
- fonts .otf
- container mkv (doesnt contain .jxl)
- plain text utf-8 (many also say markup but disagree on the implementation)
- documents .odt
- archive files (this one is causing a bloodbath so i picked randomly) .tar.zst
- configuration files toml
- typesetting typst
- interchange format .ora
- models .gltf / .glb
- daw session files .dawproject
- otdr measurement results .xml
This one exists. SEPA or ISO20022. Encryption/signing isn’t included in the format, it’s managed on transfer layer, but that’s pretty much the standard every business around here works and many don’t even accept PDFs or other human-readable documents anymore if you want to get your money.
Well, okay, let me rephrase that. It would be nice if the B2C communication used something like that too.
In Finland it kinda-sorta does, for some companies (mostly for things where you pay monthly). You can get your invoices directly to your banking account and even accept them automatically if you wish. And that doesn’t include anything else than invoices, so not exactly what you’re after. And I agree, that would be very nice.
Some companies, like one of our major grocery chain, offer to store your receipts on their online service, but I think that you can only get a copy of the receipt there and it’s not machine readable.
whats the file extension and whats the category name, compiling list in body
It doesn’t have any standardized extension. My solution uses .xml (as that’s the format internally), but it’s not anywhere in the standard. About category I don’t really know. SEPA stands for Single Euro Payment Area, but it contains quite a lot of things, https://www.iso20022.org/about-iso-20022 has a bit more info on the standard itself, but there’s no catchy category name either.
