Trepess, David and Kotaka, Nobuhiro (2008): User-Centric Development of New Metadata Tools to Enhance File- Based News Gathering Workflows. In: Proceedings of IBC 2008 September 12-17, 2008, Amsterdam, Holland. p. 8

The inevitable adoption of non-linear acquisition and storage devices will enable broadcasters to accomplish a complete file-based workflow from capture through to archive. These devices not only reduce time by removing the need for tape-to-file conversions but also facilitate a complete metadata flow throughout the production. This metadata is important because, if captured effectively, it allows files to be accurately identified and presents exciting opportunities for improving the overall speed and efficiency of news-gathering operations. Sony's R&D team is working with news organisations throughout the world in order to gain an accurate understanding of the news gathering workflows being employed. In addition, we are identifying the metadata which is most useful for these tasks, the possibilities for metadata capture and the best ways in which the metadata may be utilised to support people and their tasks. This paper describes Sony's work in R&D to understand the news gathering workflow and how this knowledge is being used to guide the development of novel tools to improve the effectiveness of future Sony products.

Trepess, David and Stockman, Tony (1999): A Classification and Analysis of Erroneous Actions in Computer Supported Co-Operative Work Environment. In Interacting with Computers, 11 (6) pp. 611-622.

In the past, CSCW systems have been studied with little consideration of the social context in which they will be used (see Ref. [1]). A framework of social context has been proposed [1] that takes the social aspects of a collaborating community to be a vital consideration in the design of CSCW systems. This paper aims to extend Mantovani's framework to deal with the issues of human error. The social context plays a large part in the cause, detection, level of consequence and recovery of erroneous actions in CSCW. This paper considers how current classification of human errors might be adapted for application in CSCW. A framework has been proposed which can be used in the analysis of the social context of CSCW.
