Property Graph

A property graph (also known as a labeled-property graph) is a type of graph model where relationships (properties) between entities are named and carry some defined properties of their own. It extends the basic graph database of linked triples to show complex connections that describe how different types of metadata relate, including greater modeling of data dependencies. However, property graphs do not have the same degree of sophistication as knowledge graphs, which tend to use more formalized schema, non-local Uniform Resource Identifiers (URIs), and are designed (in theory) to allow federating data across multiple datasets.
