The active increase of digital data, as well as the generation of new varieties of digital content, has established several possibilities and challenges in the management of the big amount of data. Traditionally, organisations have relied on Uniform Resource Locator (URL) hyperlinks to provide involved parties with access to their digitised content via the Internet. Nevertheless, over time, more of these hyperlinks become invalid. The concept of persistent identification has been developed to solve this issue. Instead of addressing data directly through its actual locator, Persistent Identifiers (PIDs) permit data retrieval by globally unique and permanent identifiers. PIDs include metadata and resolving URLs that point to the original location of data collections. As the target URLs are changing, PIDs require constant maintenance. Existing PID systems has enabled long-term stable and unambiguous references. They are already in rapid use, supporting distributed approaches at varying levels. In most of the cases, PIDs are indexed and explored by a central system. Besides infrastructural questions, the discoverability of PIDs mainly depends on their metadata classifications, which express what a given PID represents. The aim of this thesis is to explore the creation of a meta-standard for the specification of domain-specific PID registries which are exposed by an application programming interface (API), while standard and API both respect Findable, Accessible, Interoperable and Reusable (FAIR) principles.
