Change management using a thing-model on an internet-of-things platform

A computer-implemented system, comprising:

• memory storing:
• persistency services storing different versions of IoT data;
• and
• a model defining transformations of data between versions;
• and
• a server interoperably coupled to the memory and performing operations comprising:
• receiving, from an Internet of Things (IoT) device over a distributed system, an IoT data packet of IoT data in a first data format;
• determining, using an IoT data model of an IoT persistency service storing the IoT data in different data formats supporting different applications, that a second different data format of at least some of the IoT data is being used by at least one application;
• transforming, using a transformation rule in the IoT data model, the IoT data packet in the first data format to the second different data format;
• and
• storing, in the IoT persistency service, the IoT data packet in the second different data format.

A non-transitory computer-readable medium storing one or more instructions executable by a computer system to perform operations, comprising:

• receiving, from an Internet of Things (IoT) device over a distributed system, an IoT data packet of IoT data in a first data format;
• determining, using an IoT data model of an IoT persistency service storing the IoT data in different data formats supporting different applications, that a second different data format of at least some of the IoT data is being used by at least one application;
• transforming, using a transformation rule in the IoT data model, the IoT data packet in the first data format to the second different data format;
• and
• storing, in the IoT persistency service, the IoT data packet in the second different data format.
