The One Way XML Beats JSON

There are a lot of ways to add metadata to JSON or otherwise enrich it with XML-like capabilities. My favorite personally is JSON-LD

because it is compatible with RDF and you can use SPARQL queries, rule engines and similar techniques. There are methods of language tagging that are idiomatic and also the XSD schema primitives and a namespace mechanism that has fewer mathematical singularities than XML.
