Goal

Create / update / delete / search workflow objects.

Summary

This use case describes the management of a workflow object within the DataONE infrastructure.

Note: It is not clear why this should be treated any differently from the management of regular objects. A workflow could be treated like any other object within DataONE as far as object management, replication, preservation and discovery are concerned. Some additional features to support workflow staging and execution may emerge as separate use cases.
