HighWire Press, an online technology provider for over 140 publishers, announced the release of its new electronic publishing platform, H2O. HighWire has rebuilt its platform, creating a standards-based hosting solution designed to embrace the new vision of Publishing 2.0. As a fully XML-based environment, in addition to just handling XML input and output, HighWire's H2O incorporates standards like Atom Publishing Protocol, and tools such as the MarkLogic Server. The H2O platform infrastructure is flexible and modular, designed to interact with many other systems, and to be extended with emerging web services and technologies. The data store is architected to seamlessly accommodate content structured in many different ways.
