Assuming you already have access to a microformats2 parser, the algorithm defined here allows you to determine the representative h-card for a given page.

This algorithm is the microformats2 update to representative-hcard-parsing.

Contents

Algorithm

After parsing the page:

Matching URLs

URLs are to be matched as per the parsing algorithm defined in https://url.spec.whatwg.org:

Implementations

Open source implementations of the representative h-card algorithm.

Back compat

All backcompat for representative h-card parsing should already be handled by the h-card backcompat rules, implemented by a conforming parser.
