Service Creation Environments facilitate the creation of complex services and play a major role in the software industry. In this context, we aim at developing a domainspecific framework (networking domain) that uses a chain of existing ”off-the-shelf” tools that are integrated together from the design phase to the verification activities. In this paper, we propose a new meta-model that extends ArchiMate to provide a domain-specific modeling language concerning the Deep Sea Observatories (DSO). We instantiate, as a case study, DSO model with identification and localization functions from this language, and apply it to our framework that relies on an IMS platform to evaluate the service model. These functions can be orchestrated with other services (e.g. military or civil reaction) or interconnected with other SOSystems. On the one hand, this illustrates our approach in relying on Enterprise Architecture (EA) framework that respects: multiple-views, perspectives of stakeholders, and domain specificities. On the other hand, it shows the reusability of our framework by changing applications from different domains: Video Conference as a Telecom Service, and Localizations for DSO.
