SCHEMA Reference System
Among the objectives of SCHEMA was the design of a general architecture for content-based analysis, representation indexing and retrieval. All versions of the Reference System are available at

The system supports high level (semantic) descriptors and the integration of visual media indexing and retrieval with other modalities (like text and audio based indexing and retrieval). SCHEMA gives the opportunity to research institutions and organisations to take this system as a test-bed and a common dataset for the evaluation and comparison of different modules and interfaces within CBIR context.

A more detailed description can be found in Deliverable 3.2 (PDF, 8.65MB)

The SCHEMA project is kept up-to-date by the Multimedia Knowledge Group of ITI.
