The quiet revolution: How JSON displaced XML

The text explores the evolution and significance of data formats in software development, focusing on XML and JSON. XML, introduced in the mid-1990s, was designed to define structured data using a tagged notation similar to HTML, facilitating data exchange in multi-tier applications and business-to-business communications through standards like SOAP. While XML offered powerful data structuring capabilities, it was often criticized for verbosity and complexity. In the early 2000s, JSON emerged as a more lightweight, human-readable, and machine-parsable alternative, particularly well-suited to JavaScript environments due to its syntax that mirrors JavaScript object literals. JSON's simplicity and efficiency, bolstered by its close alignment with JavaScript and ease of parsing across multiple programming languages, have made it the preferred data interchange format for modern web applications, despite XML's continued presence in certain domains like RSS feeds and electronic data interchange. The text also mentions other data representation formats like GraphQL and RDF, which cater to specific application needs beyond hierarchical data structures, highlighting the diverse landscape of data formats in contemporary software development.
