This work describes Trama, a web-based system to support knowledge management in a collaborative network called LL-Habitat. The use of such system brings several advantages for the users in the network, such as the improvement of the collaboration between users, which can lead, for example, to the creation of new partnerships and projects. Moreover, users can manage the knowledge that flows in the network, directing it according to the users’ needs, in order to find matching competences. In the requirements engineering development phase, Tropos, a goal-oriented methodology, was used to provide a strong base to better understand the systems’ environment.

I would like to thank God for being my with me at all times, good or bad, giving me the strength to carry on. To my dad who taught me the value of work, for giving me not only love, but also the opportunity of having a good education, even when he had no conditions. To my mother, that was not only my pillar, but our family’s pillar. Without her support and love, I would not be here. Also, without her constantly asking me how studies were going, I would have forgotten many tests…
To my big brother and big sister, who were always by my side, giving me advices. You guys really stand for the meaning of the word “brothers” and for that, I cannot describe how grateful I am. I would like to say thanks to the friends I made in college. They were my second family, helping me to study for many, many, (many!) Calculus tests. Thanks guys, we had a great time and we will have many more in the future. Finally I would like to thank my teachers and my supervisor, Renata, for being so patience with me, for listening to all the problems I had and for understanding me. She always kept me motivated and showed me what I can achieve if I keep focused. Teachers, the knowledge you have is priceless and I cannot express what it meant to me. Thank you all, for everything!
