Apache Atlas vs Oracle Cloud Infrastructure Data Catalog

Apache Atlas is open-source software for managing metadata and governance around data assets. It supports cataloging, classification, governance, and collaboration, with predefined metadata types and tools for defining custom types, entities, and relationships. Teams can create classifications, associate them with multiple entities, and propagate them through data lineage. The interface displays lineage, and REST APIs can access and update it. Metadata search works by type, classification, attribute value, or free text, including through a SQL-like language. Fine-grained access controls apply to metadata entities and classification operations. Integration with Apache Ranger can use classifications for authorization and data masking. Atlas exposes REST endpoints for metadata types, entities, lineage, and discovery; documented integrations include Hive, HBase, Sqoop, Storm, and Kafka. Atlas is server software for self-hosted deployment, built and packaged for an environment with HBase and Solr. It is listed for Linux, web, API, and self-hosted use, at free.
