Pave the Cowpaths
I don’t claim to have invented it, because it already existed in nature. I just saw it, recognized the value of it, gave it a name, and a description, and showed its benefits. I don’t claim to be the only person to have discovered it.
Crockford is likeably humble about the origins of JSON. Rather than claiming he invented JSON he instead says he discovered it–almost as if he was a naturalist on an expedition in some uncharted territory. Looking at the Web as an ecosystem with forms of life in it might seem more like a stretched metaphor or sci-fi plot; but I think it’s a useful and pragmatic stance. The Web is a complex space, and efforts to forcibly make it move in particular directions often fail, even when big organizations and trans-national corporations are behind them. Grafting, aligning and cross-fertilizing technologies, while respecting the communities that they grow from will probably feel more chaotic, but it’s likely to yield better results in the long run.
Necessity is the Mother of Invention
Less is More
Crockford tried very hard to strip unnecessary stuff from JSON so it stood a better chance of being language independent. When confronted with push back about JSON not being a “standard” Crockford registered json.org, put up a specification that documented the data format, and declared it as a standard. He didn’t expend a lot of energy in top-down mode, trying to convince industry and government agencies that JSON was the way to go. Software developers discovered it, and started using it in their applications because it made their life easier too. Some people complained that the X in AJAX stood for XML, and therefore JSON should not be used. But this dogmatism faded into the background over time as the benefits of JSON were recognized.
JSON is not versioned, and has no mechanism for revision. JSON cannot change. This probably sounds like heresy to many folks involved in standardization. It is more radical than the WHATWG’s decision to remove the version number from HTML5. It may only be possible because Crockford focused so much on keeping the JSON specification so small and tight. Crockford is realistic about JSON not solving all data representation problems, and speculates that we will see use cases that JSON does not help solve. But when this happens something new will be created instead of extending JSON. This relieves the burden of backwards compatibility that can often drag projects down into a quagmire of complexity. Software designed to work with JSON will always work with whatever valid JSON is found in the wild.
