For selecting and composing communication services to create a networking stack in a flexible future network architecture, service descriptions are required. In this paper, we propose a language for describing communication services. The language has been implemented by using the Resource Description Framework (RDF) and evaluated by describing a set of dependencies and a complete service. Irrespective of the selection and composition methods at design time, deployment time and runtime, the language can be used any place where a networking service description is required.
