- Knows methods such as Direct Mapping of Relational Data to RDF (2012) for transforming data from the relational model (keys, values, rows, columns, tables) into RDF graphs.
- Knows that anything can be named with Uniform Resource Identifiers (URIs), such as agents, places, events, artifacts, and concepts.
- Understands blank nodes and their uses.
- Understands that URIs and literals denote things in the world ("resources") real, imagined, or conceptual.
