Open Discovery Engines¶
An open discovery engine describes a set of related open discovery services. Each open discovery service implements a specific type of analysis. This analysis is looking into the content of a digital resource and storing its findings in annotations within a discovery analysis report that is linked of the resource's Asset in the metadata repository.
An open discovery engine is hosted in the Asset Analysis Open Metadata Engine Service (OMES) running on one or more Engine Host OMAG Servers.
When an open discovery engine is called, it is passed a governance request type and request parameters. This is mapped to a call to an open discovery service through the open discovery engine definition.
