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.

MPEG-7

MPEG-7 is a multimedia content description standard. It was standardized in ISO/IEC 15938 (Multimedia content description interface). This description will be associated with the content itself, to allow fast and efficient searching for material that is of interest to the user. MPEG-7 is formally called Multimedia Content Description Interface. Thus, it is not a standard which deals with the actual encoding of moving pictures and audio, like MPEG-1, MPEG-2 and MPEG-4.

API

An () is a way for two or more computer programs to communicate with each other. It is a type of software interface, offering a service to other pieces of software. A document or standard that describes how to build or use such a connection or interface is called an . A computer system that meets this standard is said to or an API. The term API may refer either to the specification or to the implementation. In contrast to a user interface, which connects a computer to a person, an application programming interface connects computers or pieces of software to each other.

Query language

A query language, also known as data query language or database query language (DQL), is a computer language used to make queries in databases and information systems. A well known example is the Structured Query Language (SQL). Broadly, query languages can be classified according to whether they are database query languages or information retrieval query languages. The difference is that a database query language attempts to give factual answers to factual questions, while an information retrieval query language attempts to find documents containing information that is relevant to an area of inquiry.
