2.  Motivation  Software Product Line  Domain Engineering  Objectives  Methodology  FODA  Evaluation  Related Works  Conclusions

3.  Web companies that survived the dotcom crisis were using the internet as a platform, offering collaborative sites based on communities  The increasingly amount of web content is a result of  Broadband  Web cam  Cell phone  Personal cameras

4.  Greenberg positioned the collaborative systems development in the Replication phase of the BRETAM model GREENBERG, S. Toolkits and interface creativity. : Springer Science + Business Media, 2007.

5.  This scenario illustrates the opportunity for a Domain Engineering  Develop reusable software  Reducing the need of redevelopment  Keeping focus on system assembly

7.  The main objective is to find common shared applications points  Artifacts are develop to provide reuse

8.  To present a domain engineering for collaborative features of content sharing social networks  To develop a component kit for assembling content sharing social networks

16.  In the FODA, data flow is used  In this work, we use patterns for computer- mediated interaction http://www.groupwareworkbench.org.br/engenhariadedominio

17.  Architecture Modeling  Groupware Workbench Architecture  Domain Implementation  Developing software components for build Web 2.0 collaborative systems

19. GQM (Goals Questions and Methods) Analyze the domain engineering For the purpose of evaluation With respect to coverage, ease of use, and utility From the viewpoint of collaborative systems developers In the context of students of Computing Science course

20.  The first one evaluated the artifacts according to ease of use, utility, and understanding  The second one evaluated the application of its artifacts in a real context

22.  Evaluated if the software component were enough for build a web 2.0 social network  Focus Group  Brainstorming Meetings

25.  We proposed a domain engineering for building collaborative software components  We adapted the FODA method with 3C collaboration Model and Interaction Patterns  These components are not limited to the domain of social network  We provide a component kit that enables to build new collaborative social networks in the Web 2.0
