Abstract
This chapter provides the description of the overall architecture of the content level of convergence: the CONVERGENCE Middleware (CoMid). The chapter starts with the presentation of the MPEG-M standard, which provides the foundations for CoMid, then proceeding with a complete description of this architectural level. The key components of the Content level comprise a diversified set of middleware engines to manipulate Versatile Digital Items (VDIs), a Community Dictionary Service (CDS) and a Semantic Overlay. The set of middleware engines were partially borrowed and/or adapted from MPEG-M and partially designed and developed from scratch within CONVERGENCE, adopting the same design principles. The CDS and the Semantic Overlay, newly designed and developed by CONVERGENCE, when used together with the middleware engines, enable the semantic, content-based, publish-subscribe functionality of the platform.

The IMDB ontology contains a detailed taxonomy of genres in the form of a class hierarchy. The Movieontology allows representation of genres through string literals.
