Data Manager Open Metadata Access Service (OMAS)

The Data Manager OMAS provides APIs for technologies wishing to register new data assets, connections and related schema from data resources located in database servers, file systems, file managers and content managers. The caller of this interface may be the data manager itself, or an integration daemon if the data manager does not support open metadata directly.

There are specific APIs for different types of data managers and assets. These reflect the terminology typically associated with the specific type of data manager to make it easier for people to map the Data Manager OMAS APIs and events to the actual technology. However, the specific implementation objects supported by these APIs all inherit from common open metadata types so it is possible to work with the resulting metadata in a technology agnostic manner using services such as the Asset Consumer OMAS.

The Data Manager OMAS APIs needs to accommodate slight variations between different vendor implementations of data managers, along with information relating to local deployment standards. As such there is provision in these interfaces to support:

The module structure for the Data Manager OMAS is as follows:
