This user interface, and the code behind it, is provided as an example for the benefit of microformat open standards developers, and to demonstrate the clear one to one correspondence between microformat fields and microformat code. The code generated by this interface may be used for semantic web pages, structured blogging, or any other application that requires markup that is simultaneously human presentable and machine readable. Based on the hCard creator by Tantek Çelik (later updated by Ryan King), which is based on the XFN Creator (v1.0 by Matt Mullenweg, v1.1 update by Tantek Çelik).
