hCard Implementations

From Microformats Wiki
Jump to navigation Jump to search

This page is an informative section of the hCard specification.

The following implementations have been developed which either generate or parse hCards. If you have such an hCard implementation, feel free to add it to the top of the New Implementations section. If you have a page or site which just publishes hCards, please use hcard-examples-in-wild instead.

New Implementations

Add new implementations here for evaluation and classification into the below taxonomy of implementations.

Please help out by trying out these implementations and once verified move them to the grouped sections below. For now we are keeping them in grouped sections (rather than a table) because there are so many differnt kinds of implementations that it does not quite make sense to have columns that apply to all implementations. - Tantek
