User Oriented Query Language For MPEG-7 and MPEG-7 API

We propose to represent the "basic behaviors" of {MPEG-7} description tools as a set of constructor, operator and function signatures. This way of making explicit the behavior of datatypes using function signatures is commonly used to formalize data {models.A} major advantage of this proposal is that, based on signatures, functions can be implemented using different algorithms and technologies, which could be considered as an {MPEG-7} {API.} It?s important to note that the specification of signatures and their description is application independent. It therefore respects one of the major features of {MPEG-7,} which is "application independency". Implementations of the functions? cores are clearly out of the scope of the standard. Inevitably, the use of an {MPEG-7} {API} makes building {MPEG-7} applications easier and more effective as developers would not be totally dependent on the understanding of the {MPEG-7} semantics and examples part.
