Aurelius Atlas vs SemanticWorx Affirma

Aurelius Atlas is an open-source data governance platform for business users who need to discover, understand, and manage information about organizational data. Its catalog describes data meaning, quality, location, lineage, and ownership. Lineage traces processing and use from data origins to consumers; quality insights and impact analysis help identify areas for improvement. Atlas models business concepts such as domains, entities, and attributes alongside technical assets such as systems, collections, datasets, and fields. Its documentation describes REST and lineage APIs for registering producers, consumers, and transformations, and federated identity through Keycloak, including Azure Active Directory integration. Organizations can host Atlas on cloud platforms or local servers. Docker Compose is provided for trying it and is not intended for production; on-premises Kubernetes is also described. A hosted SaaS option is maintained by the team and priced according to cloud resource usage and support level. The self-hosted plan is free, with optional consulting priced separately. Atlas is distributed under the Elastic License 2.0.

SemanticWorx Affirma is a paid enterprise semantic and metadata management solution for harmonizing data architecture. Its catalog stores data models, schemas, integration schemas, and other definitions, while an enterprise semantic model records shared meanings and dataset relationships. Lineage, mapping, and transformation features show data origins and movement between sources and targets. Governance workflows support approvals, audit review, and notifications. Build Automation provides code generation, and Data Design can generate XSD and DDL for MySQL, Hana, Snowflake, Oracle, MS SQL, and SQLite. Deployment options are on-premises and cloud-based, with self-hosted and web access listed. Affirma can import schemas, ODBC sources, UML, XML, and reference data, and the site describes Databricks Unity Catalog metadata harvesting and lineage integration. Core, Professional, and Ultimate subscriptions are annual and priced by inquiry, considering users and data sources. Basic Support includes updates, ticket turnaround, a knowledge base, and a solution forum.
