hCard Implementations

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 the 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


Implementations you can use to author, create, and publish hCards.

Web-based Creators

hCard creator
Create your own hCards; also has a Dutch interface. hCard Give feedback.

Blogging and CMS tools

Search and Discovery

Conversion and Import

Implementations you can use to importing into an address book application, typically by converting hCard to vCard.

Web Services

These return vCard (.vcf) and other contact formats for easy importing into typical address book programs or other processing.

  • www.tomota.de Online address book that allows to import, export and convert hCard into vCard, ldif, csv and plain text.

Internet Explorer extension

Oomph - This Add-In to Internet Explorer will light up on pages with hCards.

Flock extension

  • ...

Open Source

Open source libraries of hCard parsers and other related code for building hCard implementations. Note: it is very likely that above implementations may be duplicated in this section. That's ok.

The hCard creator (hCard creator feedback) is a very simple, yet illustrative, open source user interface / form / script which creates an hCard in real-time as you type in a set of contact information.
  • Resumy - small tool that is capable to generate Resumes marked up using the hResume Microformat standard into a W3C valid web page.
  • Lustro is a free and open source Mac OS X application that exports your Address Book contacts to CSV, tab delimited, Google Contacts and hCards off course. It creates a single XHMTL webpage with all your contacts as hCards.

Additional Applications

This section should probably be incorporated into hCard Brainstorming.

There are numerous potential additional uses and applications for hCards on the Web. The following are merely a few thoughts and possibilities that folks have come up with:

  • As an open standard/format for Gravatars.
    • Like this.
    • Wordpress plugin with hCard based replacement for gravatar is in the make. Alper 12:59, 8 Aug 2007 (PDT)
  • Marking up individual authors of blog posts on a group blog
  • Marking up people's names and URLs in a blogroll
  • Any reference to people in blog posts (e.g. when citing them, or referencing them, or describing them, by name).
  • ...
