Internationalized Domain Names (IDNs) allow people around the world to use domain names in local languages, such as Arabic, Chinese, or Cyrillic.

XHTML Friends Network (XFN) is an HTML microformat that represents human relationships by adding metadata to hyperlinks between websites and profiles.

It defines a set of standardized link relationship values such as friend, colleague, spouse, and acquaintance through the HTML "rel" attribute, and may be used by blogs, social networks, and personal websites to describe social connections in a machine-readable format.
