Global Multimedia Protocols Group
The Global Multimedia Protocols Group (GMPG) was founded in March 2003 by Tantek Çelik, Eric A. Meyer, and Matt Mullenweg. The group has developed methods to represent human relationships using XHTML called XHTML Friends Network (XFN) and XHTML Meta Data Profiles (XMDP), for use in weblogs.
It is an informal organization who engages in experiments in metamemetics.
GMPG was founded by Tantek Çelik, Eric Meyer, and Matthew Mullenweg who developed the initial principles for XFN, the XHTML Friends Network as an attempt for the creation of a simple way to express human relationships on the Web within HTML (machine-readable).
