Apache Atlas

Apache Atlas is a scalable and extensible set of core foundational data governance services developed by the Apache Software Foundation. It enables enterprises to effectively meet their compliance requirements within Hadoop and allows integration with the whole enterprise data ecosystem. Atlas provides metadata management, data classification, lineage tracking, business glossary, and a REST API for programmatic governance operations. It supports discovery, auditing, and policy management for enterprise data assets.

Apache Atlas publishes 6 APIs on the APIs.io network, including Discovery API, Entities API, Glossary API, and 3 more. Tagged areas include Apache, Big Data, Compliance, Data Governance, and Data Lineage.

The Apache Atlas catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Apache Atlas’ developer surface includes authentication, documentation, getting-started guide, support, changelog, and 12 more developer resources.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/apache-atlas: open an issue to ask a question, or submit a pull request to add artifacts.
