# Document processing manager
The {doctitle} (DPM) is the part of the [Coveo indexing pipeline](https://docs.coveo.com/en/184/) that applies [indexing pipeline extensions (IPEs)](https://docs.coveo.com/en/206/) and [mappings](https://docs.coveo.com/en/217/).
It processes each incoming [item](https://docs.coveo.com/en/210/) before forwarding it to the [index](https://docs.coveo.com/en/204/).
