Microsoft announces public preview of Azure Data Catalog, an enterprise metadata repository, available July 13

Context & Ripple Effects
In mid-2015 Microsoft's data platform group, led by Joseph Sirosh, was stitching together the Azure data stack piece by piece: this public preview of Azure Data Catalog followed shortly before the company detailed its Azure Data Lake plans, and a year later came rights-management labeling via Azure Information Protection. The catalog is the discovery layer of that build-out — an enterprise metadata repository where organizations register and find their data sources.
First-order effects
- Enterprise customers gain a self-service way to register, describe, and search their data assets in Azure starting with the July 13 preview, with Sirosh's team collecting preview feedback to shape the commercial release.
Second-order effects
- The catalog gives Microsoft's adjacent launches — Data Lake analytics storage and Information Protection labeling — a discovery layer to plug into, letting each new service inherit the same registered-data foundation rather than standing alone.
Third-order effects
- The arc runs through 2020, when Microsoft folded this lineage into Azure Purview, a unified governance service that automates discovery, mapping, and tracking — evidence that standalone metadata catalogs were a transitional product form, absorbed into broader automated governance platforms.
The trend: Enterprise data management has moved from manually maintained metadata catalogs toward automated, unified governance services that map and track data across an organization.
