We designed and implemented a hybrid grid information service supporting both the scalability of large amounts of relatively slowly varying data and a high performance rapidly updated information service for dynamic regions. This generic implementation supports two information service implementations: ExtendedUDDI and WS-Context.

We finished implementation and testing of a first release of the Hybrid Service. This version has been successfully integrated and tested with two information service implementations: ExtendedUDDI and WSContext. The installation package for this release can be found here.
