Wikirating is a free, collaborative platform for credit ratings that aims to provide a transparent source for credit ratings of countries, companies and structured products. It is the first independent rating platform mainly based on community's contributions to feed data and information to establish independent, impartial and transparent ratings.[1][2][3]

Development of the platform started in spring 2010 by Austrian mathematician Dorian Credé and his colleague Erwan Salembier. The platform, which is based on the MediaWiki framework, went online in October 2011. By the end of 2011 around 2100 users have contributed ratings.[1]
Wikirating uses a similar rating scheme as traditional credit ratings agencies, ranging from "AAA" (highest rating) to "D" (default).[1][4]
The platform offers two rating methods.[1]
Wikirating users can vote on the rating of each country, company and structured product. Voting is limited to one vote each to prevent manipulation.
The Sovereign Wikirating Index (SWI) contains a transparent formula that takes into account various factors, believed to influence the creditworthiness of nations.
As of January 2012 the SWI contains the following five criteria (with weights):
The resulting value is adjusted by multiplying it with a "scaling factor", which is composed by the Human Development Index (HDI)[5] (60% weight), the Corruption Perceptions Index[6] (20% weight) and the Political Instability Index[7] (20% weight).
Each criterium is calibrated with respect to the relative minimum and maximum value of all countries. For some criterium a threshold value is defined in order to avoid distorted values. The calculated values are done with a spreadsheet (wr_swi_method+data_2011-09-26.xls).
The founders hope to engage the community to further improve the formula in order to provide optimal ratings.
