Multimedia content is derived from various autonomous, distributed and heterogeneous content sources. To address problems posed by content
sources heterogeneity, a service-oriented architecture is proposed to assure a
dynamic integration of multimedia content. In this work we propose a model that we call MaaS (for Multimedia as a Service), through which multimedia
content providers expose their content. Once the MaaS is discovered, its classification into category of concepts, based on domain ontology, is made.
However, content access is done through a concept hierarchy. The sport domain is used to validate the proposed model.
