I forget about that because to me it’s just about the idea of a graph, which is otherwise quite elegant. Why not have a graph type-free with just string literals; much richer information about what kind of values go where can be provided through constraints, vocabularies, etc.
My favourite serialisation has got to be dumb triples (maybe quads). I don’t think writing graphs by hand is the future. However, when it comes to that, Turtle’s great.
Because the semantics of numbers and dates matters.
It's absurd that JSON defines numbers as strings and has no specification for dates and times.
I believe we lose a lot of small-p programming talent (people who have other skills who could put them on wheels by "learning to code") the moment people have the 0.1 + 0.2 != 0.3 experience. Decimal numbers should just be on people's fingertips, they should be the default thing that non-professional programmers get, IEEE doubles and floats should be as exotic as FP16.
As for dates, everyday applications written by everyday people that use JSON frequently have 5 or more different date formats used in different parts of the application and it is an everyday occurrence that people are scratching their heads over why the system says that some event that happened on Jan 24, 2026 happened on Jan 23, 2026 or Jan 25, 2026.
Give people choices like that and they will make the wrong choices and face the consequences. Build answers for a few simple things that people screw up over and over and... they won't screw up!
