The language is equipped with an exceptionally powerful macro system, enabling developers to customize it to fit specific applications, along with a versatile runtime environment that permits on-the-fly modifications and debugging of active applications, which is particularly advantageous for server-side development and mission-critical software that requires long operational lifespans. Additionally, Common Lisp's multi-paradigm nature empowers developers to select the programming approach best suited to their particular application requirements. This flexibility not only enhances productivity but also fosters innovation in software design.

JSON, which stands for JavaScript Object Notation, serves as a compact format for data exchange. Its simplicity makes it accessible for human comprehension and straightforward for machines to interpret and create. Derived from a portion of the JavaScript Programming Language Standard ECMA-262 3rd Edition from December 1999, JSON is a text-based format that remains entirely independent of any specific programming language while employing familiar conventions found in C-family languages such as C, C++, C#, Java, JavaScript, Perl, and Python. This versatility positions JSON as an exceptional choice for data interchange. The structure of JSON is founded on two primary components: 1. A set of name/value pairs, which can be represented in different programming languages as objects, records, structs, dictionaries, hash tables, keyed lists, or associative arrays. 2. An ordered sequence of values, typically manifested in most languages as arrays, vectors, lists, or sequences. These fundamental structures are universally recognized, and nearly all contemporary programming languages incorporate them in some capacity, further enhancing the utility and appeal of JSON as a data format.

Extensible Markup Language (XML) is a versatile and straightforward text format that has its roots in SGML (ISO 8879).

This webpage outlines the ongoing efforts at W3C within the XML Activity and provides an overview of its organizational structure. The work conducted at W3C is organized into Working Groups, which are detailed on the following list along with links to their respective webpages. For those seeking formal technical specifications, you can access and download them here, as they are made publicly available. However, this is not the right place for finding tutorials, products, courses, books, or other XML-related resources. To assist you further, there are additional links provided below that may direct you to such materials. Additionally, you will discover links to W3C Recommendations, Proposed Recommendations, Working Drafts, conformance test suites, and various other documents on each Working Group's page, ensuring a comprehensive resource for anyone interested in XML.
