VisualMOQL is based on a textual query language that we developed called Multimedia OQL (MOQL)MOQL. MOQL extends the standard object query language OQL by adding spatial, temporal, and presentation properties for content-based image and video data retrieval as well as for queries on structured documents. Hence, MOQL is a general-purpose multimedia query languages. VisualMOQL implements only the image part of MOQL for the DISIMA project and combines semantic-based (query image semantics using salient objects), attribute-based (specify and compare attribute values), and cognitive-based (query-by-example) querying. This combination leads to a flexible, and yet powerful visual query interface. A query specified using VisualMOQL is translated into MOQL to make use of the MOQL parser and query processor.
