Metadata is information that travels with the raw data that provides context, provenance, security, authorship, controls, and indexing.
The number of ways that you can expand the use of data is controlled by adding metadata. It creates a change in how we look at and manage data. Instead of creating control systems that contain the data, it’s actually packaged the control infrastructure, or the data control plane, as part of the data so that all of the systems can participate in it.
We also talk about data mesh a lot in that context.
