The purpose of the open Inter VTS Exchange Format (IVEF) Software Development Kit (SDK) project is to provide potential users of the IVEF format with software tools to facilitate rapid development of software that interprets IVEF data.
IVEF is an ongoing standardization effort for the exchange of information between VTS and is actively being defined by a large group of industrial members of IALA.
This information consists of real-time tracking positions, static vessel information and voyage related information.
The IVEF SDK runs on Linux, Microsoft Windows and Apple Mac OS X & iPhone OS. It comes in the flavors C++ (with Qt bindings), Java, Objective-C and PHP. Which has been downloaded several hundred times now, not counting subversion downloads (exports).
