The API Documentation mentions (Section - Sample Use Cases) mentions that the refer to use cases using Usage API in "Open Digital Business Scenarios and Use Cases" document.
Can someone point out where this document is available?
Unfortunately, Abhi, this rubric is no longer relevant, and was probably carried over from previous versions of the user guide.
With the onset of ODA, you can find use cases and sequence diagrams in IG1228, although the coverage is by no means complete at this time.
Hope it helps.
Thanks @Jonathan Goldberg for the reference
