Before we get into that analysis, we need to ask what we mean by a fully PID-optimized world? Essentially, it's a world where persistent identifiers are registered, used and shared at all points in the research lifecycle. To be most effective, PIDs would not only be created for the people, places, and things associated with research, but would also be collected and used by funders, institutions and publishers, at the earliest possible point in the process.
For example, ORCID IDs for researchers would be captured by funders during grant application; grant IDs would be captured by institutions at the point of award; and so on. In addition, as we noted yesterday, PIDs are more than just identifiers, they also have metadata associated with them — and, vitally, that metadata should include other associated PIDs. This is often already the case, for example, for DOIs associated with ORCID records, but it needs to happen much more broadly and more completely. Think about collaborators being associated with grants, or ROR identifiers for institutions being embedded in article metadata. This early capture and association minimizes the manual entry of information and maximizes the opportunities for it to be reused.
