HTMLKontext

HTMLKontext is a web development library and design concept that focuses on contextualizing HTML content through semantic enrichment. It aims to make markup more meaningful to humans and machines by associating elements with contextual metadata, thereby improving accessibility, searchability, and application interoperability.

The project promotes the idea that HTML elements carry meaning beyond presentation and that tools should be able to reason about that meaning at runtime. It provides a modular core and a plugin system that lets developers define context rules, annotate nodes, and expose context information to downstream consumers such as assistive technologies, search engines, and client-side applications.

Key features include automatic context inference for common elements (for example headings, sections, and interactive controls), support for metadata through data- attributes or linked structured data formats, and integration with accessibility APIs via ARIA roles and properties. The library is designed to work with existing frameworks and can operate in both client-side rendering environments and server-side rendering contexts to ensure consistent context data.

Implementation is typically JavaScript-based and emphasizes a non-intrusive approach, manipulating the DOM only where necessary and providing a clear API for extension. HTMLKontext is released as open source and is hosted on public version control platforms, inviting contributions and extensions from the web community.
