Intercâmbio de dados sem as desvantagens do XML

Douglas Crockford, em seu artigo “JSON: The Fat-Free Alternative to XML”, exibe um comparativo entre os formatos para intercâmbio de dados JSON e XML, mostrando as vantagens da utilização do JSON (JavaScript ObjectNotation).

The most informed opinions on XML (see for example xmlsuck.org) suggest that XML has big problems as a data-interchange format, but the disadvantages are compensated for by the benefits of interoperability and openness.
JSON promises the same benefits of interoperability and openness, but without the disadvantages.
