Document and Node

• Documents / Nodes

A Document is a generic container around any data source - for instance, a PDF, an API output, or retrieved data from a database.

A Node represents a "chunk" of a source Document, whether that is a text chunk, an image, or other. Similar to Documents, they contain metadata and relationship information with other nodes.

Nodes are a first-class citizen in LlamaIndex.
