Looking at the development during the past years, starting back in 2006, the OX-Framework (OWS Access Framework) was designed to be usable as a basis for Java applications providing easy access to all kinds of OGC Web Services. With the re-design of the OX-Framework to its current 1.12 version, we shifted the perspective of the OX-Framework more to a collection of API modules. These modules represent re-usable middleware components and focus on the interaction with Sensor Web services. Thereby, the OX-Framework still greatly facilitates the development of client as well as server applications. Today, 52°North’s latest SPS implementation, the SOS Importer and our various Sensor Web clients already utilize the OX-Framework 1.12.
