h-card
From Just Solve the File Format Problem
h-card (formerly hCard) is one of several "microformats" released via the microformats.org site and community, intended for the representation of information in a manner that is human-readable but can still be processed by machines. In the microformats2 reformulation, it was renamed from hCard to h-card.
The format encodes all the same fields as the vCard format in the form of HTML or XML. Thus, it can be embedded in web pages and be readable this way (and styled via CSS), but has a standardized structure that can easily be converted mechanically to and from vCard and other address card formats.
