Open Data Infrastructure for Data Product Marketplaces

A glossy data product marketplace can make closed infrastructure look organized. That is not the same as making it open.

A marketplace can still create lock-in

Data product marketplaces promise discovery, reuse, ownership, and governance. Those are good goals. The problem starts when the marketplace owns the only usable copy of metadata, policy, usage telemetry, and access workflow.

If the data product cannot leave the marketplace without losing meaning, policy, lineage, and usage history, the marketplace becomes a nicer lock-in layer.

The product needs portable evidence

A marketplace-ready data product should include open table access when appropriate, catalog metadata, owner records, schema and semantic contracts, lineage, policy evidence, usage telemetry, freshness, quality signals, and deprecation paths. Buyers and internal consumers should be able to inspect those signals without depending on one proprietary UI.

OpenLineage, DataHub, OpenMetadata, Iceberg, and policy engines all cover pieces of that evidence chain. The architecture has to connect them into a product experience without trapping the product.

Open infrastructure keeps the market honest

Open Data Infrastructure gives the marketplace something better than a catalog of cards. It gives the marketplace a control model. Tables remain readable. Metadata remains portable. Policy decisions are inspectable. Usage can inform product improvement without becoming a hostage.

For adjacent context, read ODI is not just open source, data product versioning in ODI, and catalog-neutral governance controls.

What breaks first

• The marketplace card is portable, but the lineage and policy evidence are not.
• Usage telemetry improves the product but cannot leave the platform.
• Data owners approve access in the marketplace while storage credentials live elsewhere.
• Consumers discover products but cannot understand freshness, quality, or exit risk.

Questions to ask

Ask what leaves with the data product, who owns the metadata, and how policy evidence survives a marketplace change. Ask whether the marketplace reduces lock-in or simply makes it easier to browse.

Sources to start with

These primary sources anchor the technical claims in this guide.

• Apache Iceberg table specification
• DataHub lineage documentation
• OpenMetadata lineage documentation
• OpenLineage object model documentation

A marketplace should make data products easier to use without making them harder to leave.
