After almost a year of beta releases, OSE 7.0 is finally available. At its core, OSE is a C++ class library for general purpose programming, but also includes support for building event driven systems and distributed applications using a request/reply and publish/subscribe style service agent framework. The ability to interact with an application is facilitated using a HTTP servlet framework and RPC over HTTP interfaces. In short, OSE could be said to take technology from event driven real time systems, message oriented middleware, application server and web service technology and wraps it all into one. Although C++ at its core, OSE also provides wrappers for the Python programming language. This mix means that OSE serves as a useful platform for building standalone or distributed applications in Python, C++ or a mix of both. Its support of both XML-RPC and SOAP protocols through a single service interface makes it ideal for building web based services. Further information on OSE and the software itself, can be found at: http://ose.sourceforge.net This includes over 100 pages of documentation on the Python interfaces alone. The Python documentation can be viewed on the site as HTML, or as a single PDF file at: http://ose.sourceforge.net/python-manual.pdf OSE is released under the QPL. This release is the culmination of over 10 years of development, OSE first being available over the Internet in 1993.
