Overview of Security Web Services Operations at DEWS Technical Workshop (Feb 2007)

The DEWS Technical Workshop held on February 6-7, 2007, focused on Security Web Services operations including Attribute Authority and Session Manager functionalities. Services discussed included the retrieval of attribute certificates, trusted host information, and session management operations like user authentication and certificate signing. Notable progress was made on unit testing for both Python and Java implementations. The British Atmospheric Data Centre served as a key venue, exploring applications of these web services in various streams, including health and marine data.
