This document summarizes the status of the digitalSTROM server development. It discusses the design goals, timeline, and structure of the digitalSTROM server (dSS). Key points include: - The dSS has a high level of abstraction, simple objects, and open APIs to allow easy access. - Implementation is in C++ on Linux, with ports to Mac OS X and ARM underway. An open source release occurred in January 2010. - The roadmap includes adding features like SSL, installation tools, and enhancing logging/configuration. Developers are invited to contribute code, testing, documentation and more.
