In this article we present a knowledge management platform called Kim un (which means knowledge in Mapuzugun) as a technological web resource for teaching and learning Mapuzugun language. We discuss how we can generate a richness in multicultural education and diminish the otherness between different cultural groups in a society of XXI century towards a change of knowing and understanding, towards a cultural development for an e-society world. Today Mapuche language is going through difficult times, it's struggling for not ceasing to exist. As we know, the language is one of the patrimonies that defines a people identity, if the language dies, then the people and all their worldview disappears. Currently, Mapuche children are not learning Mapuzugun as their mother tongue for a variety of reasons. This situation further aggravates the problem of maintaining the Mapuche language and, with it, all the cultural richness of this ethnic group. Due to this complex scenario is that the government has implemented laws that allow a revitalization of this language, including teaching in those schools that have a high density of Mapuche students. The objective of this work is to bring together actors such as teachers, non-Mapuche and Mapuche students, researchers, Mapuche and native speakers to put the pedagogical resource for the teaching and learning of the Mapuche language as a multicultural tool as technological linguistic tools which are transversal to the disciplines of nowdays. The advances of this work are the base to create a platform focused on orienting a framework in the creation of learning virtual objects (OVAs in spanish).
