Mobi.Ubiq
The Mobi.Ubiq framework provides an open source, open standard framework for context-aware applications. Context-aware applications are systems that depend on the context of the user. In most cases these refer to location-based services (e.g. depending on the location of the user). Several object-based services are in development now that mobile phones are able to read barcodes, now RFID tags and QR barcodes are becoming more widely available, and that mobile phones have the capability to read such RFID tags and barcodes. The combination of location and object data provides a vast variety of potential context-aware services.
The Mobi.Ubiq framework enables easier implementation of context aware applications, makes it possible to compose services and provides mobile users with opportunities to discover services based on location and object data.
