Collaborative e-learning is based on a model where knowledge is created through interaction between members that interact by sharing experiences and knowledge.Linked Open Data (LOD) allow to link data with other related data in which people are interested. As a practical approach we introduce a system where is built cultural heritage knowledge from collaboration between open data published by a regional government, enriched with data from other sources of open linked data cloud like DBPedia.Mobile technologies in e-learning allow learning in any place and moment. We try to take advantage of mobile and semantic technologies, like LOD, in a collaborative e-learning environment. Knowledge is built by enriching open data that are shared by institutions to knowledge shared on Semantic Web, by using LOD techniques, leading a scenario of collaborative and human learning by linking data sources and people who share these data.The collaboration between web of data and open data from a public institution has resulted in practice, in a mobile tourism application that works as a tourist guide for citizens. Application also allows the collaboration of tour guides to add new knowledge about the cultural heritage resources. In brief, collaboration between different profiles generates knowledge and collaborative learning.
