The document discusses the application of OSGi technologies in RFID middleware, focusing on its architectural components and event-driven nature. It explores sensor integration, data measurement, and the potential for machine-to-machine (M2M) communication within various industries. Additionally, the work is part of the Aspire project, co-funded by the European Commission, highlighting the importance of compliance with industry standards and interoperability.
