H1DS: A new web-based data access system

• We present H1DS, a new RESTful web service for accessing fusion data.
• We examine the scalability and extensibility of H1DS.
• We present a fast and user friendly web browser client for the H1DS web service.
• A summary relational database is presented as an application of the H1DS API.

A new data access system, H1DS, has been developed and deployed for the H-1 Heliac at the Australian Plasma Fusion Research Facility. The data system provides access to fusion data via a RESTful web service. With the URL acting as the API to the data system, H1DS provides a scalable and extensible framework which is intuitive to new users, and allows access from any internet connected device. The H1DS framework, originally designed to work with MDSplus, has a modular design which can be extended to provide access to alternative data storage systems.
