Historically subaltern groups envisage new possibilities for the creation of community museums and exhibits. This seems to be particularly true of the Global South and, even more so, of Sub-Saharan Africa and the African diaspora to Southern America - two regions of the world where, when it concerns ethno-racial minorities and social movements, presential museums and "actual" archives have more often than not been poorly funded, ill-equipped, and underscored. This article teases out the process of creating such a digital museum that focuses on African and Afro-Brazilian heritage. It is a technological and political experiment that is being developed in a country experiencing a process of rediscovery and of the patrimonialization of a set of elements of popular culture, within which "Africa" as a trope has moved from being generally considered a historical onus to (Western-oriented) progress to become a bonus for a country that is discovering itself both multiculturally and as part of the powerful group of BRIC nations.
