The Open Data Product Specification (ODPS) is a vendor-neutral, open-source machine-readable data product metadata model. It defines the objects and attributes as well as the structure of digital data products. The work is based on existing standards (schema.org), best practices and emerging concepts like Data Mesh. ODPS 3.0 changes the data product metadata model towards a standalone model, which helps to decouple data product from the systems often directly associated with it. With help of the ODPS data product can be presented and described to the customer also as such without any need for a dataspace or other systems.
