This presentation is an overview of my PhD research related to the OpenScout project and developed during my visiting research internship at KMi. It is a working in progress. It aims to discuss a virtual social network as a knowledge space. The research field focuses on  the Colearn community. It is a Portuguese language community (Brazil, Spain, Portugal and England) interested in educational technologies whose some members are participating in the OpenScout - Tool Library social network. The OpenScout - Tool Library, developed in KMi,  is a space for communities sharing stories and tools for adapting OER. My research focuses  on the process of sharing and acquiring knowledge through a network of practice.
