Multimedia content is extracted automatically using MPEG-7 visual descriptors. The MPEG-7 uses an extended XML standard for defining structural relation between descriptors allowing creation and modification of description schemes. MPEG-7 visual descriptors are numerical representations of features - such as: texture, shape and color - extracted from an image. In this paper, the MPEG-7 is conceived as a set of services for extracting and storing visual descriptors. The MPEg-7 text-annotation tool is used for semantic descriptions. Semantic descriptions are linked to images content and conceived as a service for annotating and storing. A framework using service oriented architecture for mapping semantic descriptions and MPEG-7 visual descriptors into a pure-relational model is proposed.
