# Preprocessors

Preprocessors are generic, and their goal is to adapt and prepare the objects for preservation.

One of the main features of preprocessors is that they have an open implementation. In other words, any person with limited knowledge of programming may create a preprocessor and insert it in the system in order to add a preprocessing functionality he/she may need. The process to add a preprocessor must always be supervised and managed by system administrators and preservation administrators, and it will be their responsibility to review the new preprocessor’s functionality and safety.

In order to implement a preprocessor, we must only follow syntax patterns about the response the preprocessor must bring back to the system. In case of doubt, please ask the **LIBNOVA** consultants, who can guide you in the design of the new preprocessor.

In the main screen, we can see a list of the preprocessors available in the system with their status (active / inactive), edit the preprocessor or access the detail.
