Mostly off topic, but why is the spec for JPEG and JPEG XL paywalled? I wouldn't call them open standards if they're not available free-of-charge to the public.

It's an open standard because the concepts and reference implementation are free and open source even if the PDF is paywalled. Realistically you could just pirate the PDF and write a jpeg xl encoder/decoder and your code wouldn't be infringing on any patents.

Seems "closed but royalty free" would be a more accurate description then.

		Splitting hairs on terminology I guess. Very few people are interested in the PDF that specifies the format vs being able to include decoders in software and on devices without paying a royalty for every device. There are alternative documents and the last draft copy which are free legally. As well as the reference code.

"Open Standard" means "Anybody is allowed to buy it"
