An Object-Oriented Query Language for Multimedia Database Systems

In this paper, we propose a general-purpose multimedia query language that is built upon a set of generalized n-ary spatio-temporal relations and object-oriented modelling paradigm for multinnedia data. We present a grammar for the query language and elaborate how various functiona;!ities such as declartion of multimedia data, specification of spatio-temporal logic, expressio~l of spatio-temporal semantics for content-based retrieval of irnagelvideo data, composition of multimedia documents, and orchestration of presentations can be supported through this language. Currently, the language is being implemented using object-oriented concepts imd the Postgres database management system.
