This document summarizes a conference on exploring services held in February 2010. It discusses how digital technologies are transforming the music industry through new distribution methods and relationships between players. It then describes the Febos project, which aims to provide web services for collaborative music creation online. These services support various stages of the music process by different roles. The document outlines the service-oriented approach taken and models used, including use case models and service process models. It provides an example process model for managing scores and describes the open-source technologies used to implement the Febos project.

Service-oriented MDA-Based approach (SOD-M)
De Castro, V., Marcos, E., Wieringa, R.
Ignacio López, Antonio Cañabate, Ruth Raventós
• Services are the first-class objects for the whole process of the IS

• It is an MDA-based approach by extending CIM, PIM and PSM
levels,
• It uses UML with a service-oriented profile as modeling language
