Introduction

The Knowledge Base (KB) is structured around Identifiers as the core entities, with Providers playing a crucial role in the management and distribution of these Identifiers.

This document presents an in-depth theoretical analysis of Identifiers and Providers, their roles, and how they interconnect within the KB model. The KB serves as a centralized repository for Persistent Identifiers (PIDs), ensuring their governance, interoperability, and compliance within research and digital environments.
