Explains object layers, interfaces, connectors, deployment options, and governance features without detailing implementation procedures.

As explained in Architecting an Apache Iceberg Lakehouse

An open-source catalog and metadata-management system designed to provide unified access to distributed data assets.

Apache Gravitino is an open-source, federated metadata lake and governance layer for unified access to distributed data and AI assets. Its geodistributed architecture addresses heterogeneous storage, regional deployments, and multiple metadata domains. section 7.4.6

Organize metadata through a multilayered object model:

Metalakes scope metadata by organizational group or tenant. section 7.4.6
Catalogs connect to sources such as Iceberg, Hive, Kafka, and HDFS. section 7.4.6
Schemas and tables represent structured data, while filesets, models, and topics cover broader data and AI assets. section 7.4.6

Integrate Iceberg-aware engines through the Iceberg REST Catalog interface, or connect other systems through REST, Java, and Python APIs. Role-based access control, tags, audit logging, and enterprise authentication support centralized governance. section 7.4.6

Multiregion governance

A global organization using Spark, Flink, and Trino can consolidate metadata across clouds and regions, enforce consistent policies, and manage tables, models, and streams through a federated catalog. section 7.5.3 section 7.5.5
