Device Metadata

Every device provides some or all of the following data objects:

  • Device settings that are available in the form of Device context variables.

  • Device operations available as functions of a Device context. Iotellect Server also creates one action per every device operation for convenient interactive or non-interactive execution of those functions.

  • Device events, i.e. events of a Device context.

  • Device assets for logically grouping settings, operations and events into a hierarchical group tree.

The unified name for definitions of device settings, operations, events and assets is device metadata.

The metadata is retrieved from a device during full synchronization.

For each of the data objects (assets, variables, functions, or and events) associated with the device, the following properties are shown:
