The Data Product Descriptor Specification (DPDS) defines a declarative and technology-independent standard to describe a data product in all its components. It allows human agents (e.g. analysts, data scientists, etc..) and digital agents (e.g. other data products, BI tools, planes of the underlying data mesh ops platform, etc..) to operate, discover and access a data product. When properly defined, an external agent can understand and interact with the data product with a minimal amount of cognitive load and implementation logic.
