MF2marked

MF2marked is an open-source software project that provides tooling for working with microformats2 data on the web. The project focuses on detecting, extracting, and presenting the structured data embedded in HTML using the microformats2 specification.

It analyzes HTML to identify common mf2 patterns such as h-card for person or organization profiles, h-entry for posts, h-event, etc., and converts them into a machine-readable representation. The typical output is a JSON-like structure listing MF2 items with type and properties, enabling developers to programmatically access authors, dates, names, content, and other metadata.

MF2marked is designed as a library and, in some deployments, a command-line interface. It can be integrated into web servers, static site pipelines, or client-side applications running in browsers or Node.js. It emphasizes compatibility with content that follows the standard microformats2 vocabulary and can be extended to support custom microformats.

Limitations and considerations: it relies on correctly marked-up HTML and may be affected by dynamic content loaded after initial render. For dynamic sites, additional rendering or scripting may be required to expose mf2 data. The project is typically distributed under an open-source license, and contributions from the community are encouraged.
