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
