# Document Classification

Documents can be classified into certain top-level categories.

These document-level metadata can in turn be used to improve case level analysis of the relevant case information found in those documents, as well as give more contextual information to users in the UI.

Sixfold's API allows its consumers to specify the top-level category / classification of a document when they:
1. Create a case with documents
2. Add documents to a case
3. Specify files to add to a case from a third party integration

The sections below detail the supported top-level categories per product line.
