An original plug-in architecture with a support technology have been created and used for the improvement of geoinformation software system INTEGRO. The technology in question can be embedded into the pre-existing application and allows to create an efficient, portable, object-oriented code for extending the application with pluggable modules. A model-driven approach is used to provide a binary interface between the host application and the extension modules, for which interface code in the programming language of choice (C++ for INTEGRO) is generated on the basis on XML descriptions. The technology defines interfaces and alogorithms used to discover extensions, and on its basis a Model-View-Controller like UI architecture was developed which allows to weaken GUI vendor lock-in for the application.
