# About the Cognite EDM extractor

> Extract data from Landmark Engineers Data Model (EDM) server to the Cognite Data Fusion (CDF) staging area through OData protocol from DecisionSpace Integration Server (DSIS).

You can set up the extractor for both **full-load** extractions and **incremental** extractions. You load data incrementally by adding the [delta-supported EDM entities](/cdf/integration/guides/extraction/edm/edm_entities) to the `entities` configuration parameter and set a schedule for checking incremental EDM entities with the `gracePeriod` configuration parameter. The extractor creates a CDF RAW table for each EDM entity.
