There Are New Markets for Industrial IoT Data
measurements to gauge the health of a machine .
For data trading purposes , there are ways to package these different data types .
� Raw data – this may be encoded , implying some translation effort for a third-party user , or in an openstandard format .

Value-added data – examples include clean data ( removal of duplications , interpolation where there are data gaps , translation into an openstandard format ), sub-sampling to reduce data volumes ( a trade-off that reduces dynamic richness ) and other approaches to aggregation ( as applicable to Edge computing applications ).
Contextualized data – this involves packaging data with semantic descriptors for ease of interpretation by IIoT applications . For example , a temperature sensor might transmit a raw-data value of 37 . By packaging this with semantic data to indicate the unit of measurement , precision and range it becomes more valuable to an IIoT application . That is because two separate and potentially unrelated entities , sensor and application , can recognize one another and exchange data with less customization effort . Semantic descriptors also facilitate interoperability and allow industrial firms to multi-source instrumentation components .
A necessary complement to these data packages is a certification framework . This sets standards for how data owners supply data . It also assures users about the quality , service support and availability of data streams . The Open Data Institute offers a pioneering example through its proposed scheme .
ODI Data Certification Framework
BRONZE : data is openly licensed , available with no restrictions , accessible and legally reusable . SILVER : satisfies the Bronze requirements , the data is documented in a machine readable format , reliable and offers ongoing support from the publisher via a dedicated communication channel . GOLD : satisfies the Silver requirements , is published in an open standard machine readable format , has guaranteed regular updates , offers greater support , documentation , and includes a machine readable rights statement .
PLATINUM : satisfies the Gold requirements , has machine readable provenance documentation , uses unique identifiers in the data , the publisher has a communications team offering support . This is an exceptional example of an information infrastructure
