Class MetadataHighwayServicesClient

java.lang.Object

org.odpi.openmetadata.repositoryservices.clients.MetadataHighwayServicesClient

All Implemented Interfaces:

AuditLoggingComponent

public class MetadataHighwayServicesClient
extends Object
implements AuditLoggingComponent

The MetadataHighwayServicesClient supports the OMRS Metadata Highway REST API. Requests to this client are translated one-for-one to requests to the metadata highway service since the OMRS REST API has a one-to-one correspondence with the metadata highway API. The URLs for the REST APIs are of this form:

• restURLroot - serverURLroot + "/servers/" + serverName
• rootServiceNameInURL - "/open-metadata/repository-services"
• userIdInURL - optional - "/users/{0}"
• operationSpecificURL - operation specific part of the URL
