Knowledge graphs and ontologies are becoming increasingly important in the context of making data and metadata findable, accessible, interoperable, and reusable (FAIR). We introduce the concept of Semantic Units for organizing Knowledge Graphs into identifiable and semantically meaningful subgraphs. Each Semantic Unit is represented in the graph by its own resource that instantiates a Semantic Unit class. Different types of Semantic Units are distinguished, and together they can organize a Knowledge Graph into different levels of representational granularity with partially overlapping, partially enclosed subgraphs that users of Knowledge Graphs can refer to for making statements about statements. The use of Semantic Units in Knowledge Graphs supports making them FAIR and increases the human-reader-actionability of their data and metadata by increasing the graph's cognitive interoperability by increasing its explorability for a human reader. We introduce a minimal prototype web application for a user-driven FAIR Knowledge Graph that is based on Semantic Units.
