In their own words
Aristotle Metadata Registry
Aristotle Metadata Registry is a browser-based registry for recording and governing business knowledge about data in a central, searchable system. It supports data dictionaries, code lists, business glossaries, vocabularies, performance indicators and classifications. Search covers definitions, codes and links, with spelling suggestions, filters and facets. Rich-text editors include spell-checking, linked definitions and wizards that identify similar content. Teams can track issues, peer review metadata, inspect a complete audit trail and run automated quality checks. Governance workflows record endorsement decisions and control publication permissions through business rules. Documented APIs connect data systems, and custom integration services are available. The maker describes AWS cloud hosting, a 99.9% uptime guarantee and deployment within one day. Standard Cloud hosting is included with subscriptions; Secure and Protected Cloud add isolation. Plans specify author and collaboration licences, while Micro and Mini limit storage to 20,000 and 50,000 metadata items. Listed plans range from $3 a month to $25 a month.
DataHub
DataHub brings technical metadata, business knowledge, and documentation together for enterprise data and AI agents. It is available as self-hosted Core or as managed DataHub Cloud. Cloud provides natural-language search, an Ask DataHub chat agent, smart ranking, and a hosted MCP server that connects AI tools to its catalog. Its observability tools run automated schema, freshness, volume, and custom quality checks, with AI anomaly detection and incident workflows. Cross-platform, column-level lineage traces data from sources through transformations and AI models to downstream assets. DataHub Cloud has more than 100 pre-built connectors and names Slack, Microsoft Teams, Chrome, and BI tools among its native integrations. Cloud is described as SOC 2 compliant, with role- and attribute-based access controls and an in-VPC execution option for sensitive sources. Cloud availability is described as SLA-backed at 99.5%. DataHub Core is free to deploy, but requires users to handle installation, configuration, upgrades, uptime, and troubleshooting. Cloud pricing depends on data volume, users, and selected capabilities. A Google Cloud offer advertises a 21-day Cloud trial with a dedicated instance and full platform access.
