Objectives

The objective of the LYNX project is to deliver an Enhanced Multimedia Object System for networked multimedia applications. A multimedia object-oriented system will be delivered allowing distributed applications developers to access many different types of servers.

The kernel of the system will be object data server (ODS), which is an object-oriented database management system with enhanced support for large multimedia data, as required for the storage of real-time video and audio. The ODS provides a Canonical Model and Declarative Query Language. It supports C++ and will be fully portable to a wide range of Unix platforms with clients running on either Unix or Windows machines. The hardware support for the storage and retrieval of multimedia data will be provided by the Object Storage Processor (OSP). This is a low-cost multiprocessor machine which acts as a real-time video and audio server, and directly communicates with the multimedia I/O client devices, under the control of the ODBMS.

A CORBA-compliant Object Request Broker will be used to provide applications with a uniform view of the system with the multimedia servers as one type of component (object). Transparent access to objects stored in different systems will be provided.

Progress and Results

The first phase of the project has been centred on three main aspects: specification of the system and its main components, first partial implementations and market assessment tasks.

The LYNX system has been completely specified. The main aspects are: The Canonical Model to be provided by the Object Server, the object oriented query language (codenamed UGL), the C++ support, the distribution support, the multimedia storage strategies and the special purpose protocol for the transfer of multimedia data. Regarding the first partial implementations, a SVR4 implementation of the CORBA compliant Object Request Broker is already available, as well as the low level store of the ODBMS.

A big multimedia application survey has been conducted as part of the market assessment task. Results from this survey have been used to refine the system specification and to establish the requirements for the demonstrator application to be built.
