As someone who has gotten into the idea of semantic Web long after XHTML was all the rage[0], I somewhat resent that semantic Web and XML are so often lumped together[1]. After all, XML is just one serialisation mechanism for linked data.
[0] I don’t dislike XHTML. The snob in me loves the idea. Sure, had XHTML been The Standard it would have been so much more difficult to publish my first website at the age of 14 that I’m not sure I would have gotten into building for Web at all, but is it necessarily a good thing if our field is based on technology so forgiving to malformed input that a middle school pupil can pass for an engineer? and while I do omit closing tags when allowed by the spec, are the savings worth remembering these complicated rules for when they can be omitted, and is it worth maintaining all this branching that allows parsers to handle invalid markup, when barely any HTML is hand-written these days?
[1] Usually it is to the detriment of the former: the latter tends to be ill-regarded by today’s average Web developer used to JSON (even as they hail various schema-related additions on top of JSON that essentially try to make it do things XML can, but worse).
The semantic web took on the XSD data types
https://www.w3.org/TR/xmlschema-2/
even though a lot of tools and standards (I'm looking at you SPARQL) don't really support them. My favorite serialization for RDF is Turtle:
https://en.wikipedia.org/wiki/Turtle_(syntax)
That is a good point, if you consider XSD then that is an XML connection, it starts to become a bit complicated and I see why people start to dislike it. 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!
