OMAG Common Services (common-services)
This module provides common services to clients and the specialized services that run in the OMAG Server.
First-Failure Data Capture (FFDC) Services - supports common exceptions and error handling. It can but used by clients and server-side services.
Metadata Security - supports authorization of access to OMAG Services and specific metadata instances.
Generic Handlers - supports the management of specific types of open metadata elements. The generic handlers provide services to translate OMAS requests built around that service’s private beans into calls to the repository services (through the repository handler).
Repository Handler - supports access to multiple related metadata instances from the Open Metadata Repository Services (OMRS). It manages the provenance checking and translates repository services (OMRS) exceptions into Open Connector Framework (OCF) exceptions that are used extensively across the access services (OMASs).
In addition, there is a shared metadata management module for server-side services that make use of the beans defined in the frameworks that underpin Egeria.
- OCF Metadata Management - managing metadata about assets, connections and all of the different types of metadata defined in the asset properties in the Open Connector Framework (OCF).
