Status of MPEG-21 and XrML

At Thailand we processed all of the submissions in response to the CfP. After a series of experiments to test various aspects of the proposals, XrML was selected as the base architecture for the REL development going forward. We are currently developing core experiments to help establish whether certain other concerns can be met by XrML as it was proposed or if additional development is required. An example of one these areas of concern is size of the expressions when delivered to small devices that have limited processing power and memory such as phones, hand held devices and other limited purpose consumer electronics. We are in the process of defining what are referred to as Core Experiments employing detailed Use Cases to establish areas for focus in the development process. It is expected that we will have a fairly substantial Working Draft, in MPEG parlance, coming out of the Korea meeting in March and a largely stable specification by July of this year. After that the formal review, comment and voting procedures of MPEG are expected to extend the process of getting to a published ISO standard through to June/July 2003. As someone actively involved in this effort over the past year and a half I would be glad to answer any questions offline for those that would like to delve more deeply.
