A LEGO-like Metadata Architecture for Image Search & Retrieval
Rubén Tous, Jaime Delgado · 2009
This paper proposes a set of architectural patterns for the design of interoperable image search&retrieval systems on top of the latest standards in the area, ISO/IEC 15938-12 (MPEG Query Format) and ISO/IEC 24800 (JPSearch). The work introduces the notion of a "composable metadata model" as a means to allow the usage of multiple metadata ontologies together, along with mechanisms to specify semantic mappings among them. The paper also studies the process to choose a Core Metadata Ontology (based on the work taking place at the W3C Media Annotations Working Group), which plays the role of a minimal lingua franca among the different systems, providing a basic level of interoperability.
