• Common types for open metadata - these types are built from the Apache Atlas type system and define the types stored in the graph database as well as payloads for notifications and APIs
• Open Metadata Repository Services (OMRS) - Open metadata repository APIs and notifications to enable metadata repositories to exchange metadata in a peer-to-peer metadata repository clustercohort.  This capability is located in each metadata repository and collectively they enable what is referred to as the "metadata highway".
• Open Metadata Access Services (OMAS) - Consumer-centric APIs and notifications for specific classes of tools and applications.  The OMAS services call the OMRS to access metadata from any open metadata repository.
• New frameworks to complement the Atlas Hooks and Bridges
  • Open Connector Framework (OCF) - provides factories for connectors with access APIs for data resources and metadata together.  The OMRS is also built as a set of metadata repository connectors and the OMAS services use the OCF to connect to the appropriate OMRS connector.
  • Open Discovery Framework (ODF) - provides management for automated processes and analytics to analyze the content of data resources and update the metadata about them.
  • Governance Action Framework (GAF) - provides audit logging and governance enforcement services for implementing enforcement points in data engines, security managers such as Apache Ranger, and APIs.  It also adds stewardship services for analyzing audit logs and resolving issues identified in exceptions raised by the enforcement services.
• Open Metadata Graph Repository - A set of stores linked together with a graph database.  These stores provide linkage between business, technical and operational metadata along with logs for auditing, operational lineage, metering and exception management..
• Open Lineage Services - Services for collecting and querying lineage information across multiple heterogeneous metadata repositories
