Table 1
Overview of the use cases collected by RDA WG PIDINST. Submission is the month of first use case submission by authors to the WG. Completed is the month during which the use case was completed with the required metadata. In some instances, the metadata was provided later. For UC4 the authors didn’t provide the metadata; the use case was thus not completed (N/A). For UC1, UC5, UC8, and UC15 the metadata was provided after October 2018; these use cases were thus not considered in the metadata analysis.
