It has become good data practice to use persistent identifiers (PIDs) to identify digital data products whether a product is a collection, a file, or an object of some type. Naming solutions for digital data products eventually resolve a PID down to the digital object it identifies, but the current landscape is limited by multiple solutions with weak interoperability, and inconsistent protocols for getting from PID to data object. In a world of increasing PID use, we will soon be awash with billions of PIDs that all resolve to data objects using various inconsistent and unpredictable approaches, making it difficult to build higher level services that cross the various approaches.
In the initial 12+24 month project, we stood up and supported a robust PID testbed (called the RPID testbed (pronounced "rapid") to stimulate and enable evaluation of powerful new complementary outputs of the Research Data Alliance (RDA) in PID oriented data management. The testbed is responsive to data driven priorities in science and education, specifically as part of the cyberinfrastructure ecosystem that accelerates a broad spectrum of data-intensive research (NSF Director unveils 2016). The advancements developed and tested here we believe have the transformative magnitude to stimulate an entire ecosystem of new discovery services for research data.
During the Enhanced RPID project which continued the work on the foundational services set up during the RPID project we will research Repository Mapping Services to allow the RPID service to be utilized without refactoring of data repositories and the Digital Object Interface Protocol (DOIP) implementation which allow direct operational interactions with Digital Objects.

Open Access for Data Science Researchers
- The RPID testbed can be used for research, education, non-profit, or pre-competitive use
- The RPID testbed assigns only test handles, allowing for exploratory work.
- Handles assigned by the testbed will be on a project basis, to avoid collisions. Your prefix will be 11723.9.test.(proj_name)
- Projects interested in using the testbed are strongly advised to join the RPID User Advisory Group
- Follow the work at https://github.com/rpidproject.
- To join the RPID User Advisory Group or otherwise reach us, we are at firstname.lastname@example.org
- Please contact the RPID working group at email@example.com to get started. You will register your project, be assigned a prefix, and can then start using the services.
