Enterprise Services Repository is ...

“… the central repository where service interfaces

and enterprise services are modeled and their

metadata is stored.”

Services Registry - UDDI V3compliant registry that supportspublishing, classifying anddiscovering services

Services Registry

ES Repository - The metadatarepository of all service objects forenterprise SOA


Key Usage Scenarios

Focus: Process Component architecture modelsin ES Repository, Drill down to standards basedservice interface design

Value: Enable SOA Governance

Benefit: Transparency into Business Semantics,Contextualization of Service metadata, Easyaccess to Enterprise services & gap analysis.

Focus: Model Service Interface based on GDTs,Provide Service Metadata, Seamless Toolintegration

Value: Manage service metadata in one centralrepository

Benefit: Enable reuse of design time artifacts,End to end modeling support, Governeddefinition of SOA assets.

Process Visibility and Design Governance Service Provisioning

Focus: Use services defined in ES Repositoryfor consumption in A2A and B2B scenarios

Value: Enable integration in heterogeneouslandscape

Benefit: Collaboration knowledge of non-SAPsystems, Support for defining IntegrationScenarios

Focus: Composition tools query Repository-Registry to discover services

Value: Composite Application Development

Benefit: Contract first development process,Easy discovery, consumption & composition.
