The scope of this standard is to measure the maturity of objects in Internet-of-Things (IoT) environment, namely IoT objects. IoT objects shall represent things or devices or the entire system. The standard defines the mechanism and specifications for evaluation, grading and ranking of the performance of IoT objects by using indicator values, referred as IoT Index (IDex). IDex shall classify the objects into multiple levels of performance and give a quantitative representation and indication of the performance of objects. IDex shall manifest guidance on blending of IoT objects to evolve into better performance.
