Summary

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

Motivation

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

Motivation

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.

Motivation

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

Software Product Lines

Domain Engineering

The main objective is to find common shared applications points

Artifacts are develop to provide reuse

Objectives

To present a domain engineering for collaborative features of content sharing social networks

To develop a component kit for assembling content sharing social networks

Artifacts Evaluation

GQM (Goals Questions and Methods)Analyze the domain engineeringFor the purpose of evaluationWith respect to coverage, ease of use, and utilityFrom the viewpoint of collaborative systems developersIn the context of students of Computing Science course

Artifacts Evaluation

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

Conclusions

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
