NSDLNational Science Digital Library

Oracle Service Registry

  • Purpose: is for any kind of service metadata or artifact
  • Sun's Service Registry (now Oracle Service Registry) was implemented to provide SOAService-Oriented Architecture Visibility.The registry provides awareness of service descriptions to help consumers determine their willingness to interact with the service. The registry could also provide awareness of consumer descriptions to help providers determine their willingness to interact with consumers.
  • as it is commercial and has no free download, I could not test the functionality.

  • DCDublin Core Registry is just for discovering the DCDublin Core elements, terms and vocabularies. You cannot register own collections.
