OpenKM is a Open Source electronic document management system, which, due to its characteristics, can be used by large companies as well as by the small ones, as a useful tool in knowledge management processing, providing a more flexible and lower-cost alternative to other proprietary applications.

The use of knowledge management systems by a company helps it to manage intelligence on the resources available to the company, more efficiently. This leads to a medium-term increase in productivity. Using these systems, the information, as well as the knowledge generated within the organization, can be universally accessed.

OpenKM is a document management application with a web user interface that allows the following operations to be carried out: sharing, setting security roles, auditing and finding enterprise documents and registers. With OpenKM users can easily collaborate and communicate.
