Fixed-mobile hybrid mashups: experiences and lessons on applying the REST software architecture principles to exposing mobile operator services

Data sources used for creating mashups rarely include anything from the vast potential of the mobile domain. However, many enablers and pieces of useful information already exist for such mashups, both on the device side and on the operator network side. The lack of mashups in this fruitful area stems partly from the difficulties in accessing such data. This paper describers the application of Representational State Transfer (REST) principles to opening up mobile-specific assets in order to enable the creation of compelling “fixed-mobile hybrid” mashups; mashups utilizing information both from existing Internet sources as well as mobile-specific data sources. We present alternative architectures for the deployment of such a system, discuss the ecosystem implications of open APIs and provide lessons learned when implementing a proof-of-concept system with a subset of the designed API and demonstration
