The Web’s potential for distributed programming has been proven not only in the business realm, but also in the accelerator controls domain. Web Services describes clients and servers that communicate over the Internet’s Hypertext Transfer Protocol (HTTP) using predefined Internet-based Application Programming Interfaces (APIs). It is the uniqueness of Web Services transactions such as cloud computing, data sharing, and data archiving that give rise to the security concerns of Web Services (authentication, data integrity, non-repudiation, and privacy). At Argonne National Laboratory’s Advanced Photon Source, Simple Object Access Protocol (SOAP)-based Web Services were implemented into the Integrated Relational Model of Installed Systems (IRMIS) as the application interface to Oracle’s Content Server document management software. This report reviews the basics of Web Services, cyber-security issues that are inherent for Web Services, current Web Services security implementation practices, and future directions of Web Service security development efforts where the overriding goal of Web Services security is to focus on managing risk and protecting data.

Science Studio is a web portal, and framework, that provides scientists with a platform to collaborate in distributed teams on research projects, and to remotely access the resources of research facilities located across Canada. The primary application for Science Studio is to provide scientists with remote access to the VESPERS beamline at the Canadian Light Source synchrotron in Saskatoon Saskatchewan, and to readily process data from this beamline at the SHARCNET high performance computing facility in London Ontario. The VESPERS beamline is a complex instrument that is composed of many devices, such as valves, motors and detectors, which are all controlled through the low-level EPICS control system. Science Studio implements a simple, intuitive and functional web-based interface to the beamline for device control and data acquisition. The Science Studio experiment management system allows the acquired data to be easily organized and shared with the research team. This paper will provide an overview of the design, implementation and capabilities of the Science Studio system, with a focus on remote control of the VESPERS beamline.

This paper details the approach the Australian Synchrotron is using, in collaboration with the Australian Neutron Source (Opal) for some of the data and Metadata management issues. It explores the data and user policies, describes the quantity and quality of data and demonstrates the way forward based on both existing and future directions in e-research, network communications, user proposal and material databases, portal technologies and integration techniques. The role of standards for access and metadata creation is also explored. This work is funded by an educational infrastructure grant administered by Australian National Data Services.

The interface lay of Diamond's accelerator and photon beamline control systems have predominately been implemented as VME based systems. Forthcoming control systems, for new photon beamlines, have requirements necessitating a divergence from Diamond's adopted design patterns, including a reduction in available rack space and the management of hardware obsolescence. To address these, a new standard based on PCs and Ethernet field buses to the instrumentation has been defined. This paper will present the new design, how the design transition is being effected and the key benefits to Diamond.
