How to buy ISO 20022?

I'm curious, how does one go about purchasing ISO 20022? Is it an asset that can be traded on a cryptocurrency exchange? Or is it something that is more akin to a standard or protocol that organizations need to adopt and implement? Can you walk me through the process of acquiring or accessing ISO 20022, and what kind of entities are typically interested in doing so? I'm looking to gain a better understanding of the financial and technological implications of this standard.
