Abstract: The Space Telescope Science Institute (STScI), in collaboration with the European Coordinating Facility (ECF) and the Canadian Astronomy Data Centre (CADC), is studying the development of an enhanced archive for the Hubble Space Telescope (HST). Distinct from (but complimentary to) the existing archive system at the STScI, development of this enhanced archive affords the opportunity to leverage modern architectural and design principles toward meeting project objectives and serving the archive community. To wit, the STScI is designing the entire system as a service-oriented architecture (SOA). Composed of loosely-coupled, highly-interoperable Web services, an SOA embodies a great deal of flexibility in meeting future needs placed on the HST archive while also positioning it well within the emerging Virtual Observatory (VO) framework. A high-level architecture for the enhanced archive at the STScI is presented.
