hCard+XFN supporting friends lists

Welcome! If you have an account on any of the following services, you already have a list of your friends' hCards with your relationship to them in XFN which you can provide to other services to save time by either importing or subscribing to social network information so you can change it on one site, and have other sites automatically updated, rather than having to re-add/remove all your social network contacts multiple times every time you meet a new person, decide to unfriend someone etc.

Implement hCard XFN supporting friends lists

Want to implement hCard+XFN on your site so you can list it here?

1. Markup friends with hCard. See the hCard authoring page for how to mark-up names, links, icons of people in friends lists with hCard.
2. XFN on friend links. Friends lists should be marked up with XFN per XFN clarifications: mapping community site friends. See also the XFN: Getting Started page for how to markup links to people with XFN. See also the hCard examples: hCard and XFN which demonstrates this and the previous step quite well.
3. rel="me" to a user's other URLs. Hyperlinks to users' home pages or blogs should have the XFN rel="me" attribute to support user-driven (since the user chooses the URL to link to) identity consolidation.
4. rel="me" on "View All Friends..." links. If a user profile page on your site links to a separate page for that user's friends list, add rel="me" to that link.
5. rel="me" on friends list pagination links. If your site paginates a user's friend list into multiple pages, be sure to add rel="me next" to your "Next" pagination hyperlinks, and similarly rel="me prev" to your "Previous" pagination hyperlinks.

Please also consider implementing hCard user profiles.

Implement import XFN friends lists

Want to implement importing (and preferably subscribing to) XFN friends lists on your site so you can list it here?

In addition to implementing hCard XFN supporting friends lists yourself (see above), do the following:

1. Provide a user interface to "Import Friends" (like a button or menu item)
2. When chosen, provide a text input field for the user to enter their profile URL (such as their blog or XFN friends list URL). If you already have the user's "Website", pre-fill the field with it, or if the user has many "Other Profiles", pre-fill the field with the first, and let the user pick any of them with a Select pop-up menu, or provide the user the option to just import XFN from all of them at once.
3. Parse the XFN at the URL(s) given (links with rel="contact" or "acquaintance" or "friend" etc.) and check to see if there are any users on your site with any of those links as their rel="me" "Website" or among their rel="me" "Other Profiles" and add them to a list of people to invite. Crawl any symmetrical rel="me" links, especially symmetrical rel="me next" and/or rel="me prev" friends list pagination links for additional URLs to parse for XFN. Consider also parsing those URLs simultaneously for hCards that have those XFN links as class="url" hCard properties, and if the hCards have additional contact information such as instant messaging or email, add them to the list of people to invite.
4. Present the list of people to invite, perhaps sorted by "closeness" of XFN relationships (e.g. list family relationships before just romantic relationships before just friends before just professional relationships before just acquaintances before just contacts before just met etc.) with a "Add Friend" button next to each. When clicked, use XHR to add that person without altering the overall list, and change the Add button into a Cancel button. Perhaps put an "Add all" button at the top (or bottom) to let the user simply add everyone listed with one click.
5. Consider also providing a checkbox "[x] Subscribe to XFN friends" which would automatically run this import perhaps once a day and notify the user of new contacts found that they may want to add, and similarly present an "Add all" button.

Sites that should support hCard and XFN

See hCard advocacy - hCard XFN friends lists.

For more information

In addition to the previous "Implement" sections, see the hCard authoring page for how to mark-up information about a person with hCard, and XFN getting started page for how to mark-up friend links with XFN.

Join the microformats community, in particular the #microformats IRC channel on irc://irc.freenode.net#microformats and the microformats-dev mailing list, and send a message stating that you'd like to add hCard to the profiles and hCard+XFN supporting friends lists (and importing thereof) to your website.

Please also consider implementing hCard supporting user profiles.
