Summary
This is a requirement, not a use case. DataONE needs to ensure that content is suitably exposed by appropriate, and standard mechanisms to ensure that non-DataONE indexing and search mechanisms can index and provide discovery functionality for content available in the DataONE system. Note that such indexing can not violate access control policies for the content, and so indexing of all content should only occur with trusted services, and only public content should be accessible to services for which limited or no trust relationships have been established.
