OpenKM DMS for National Assembly of Republic of Serbia

Jul 2014 – Jul 2014
Project description: We installed and configured the OpenKM Knowledge Management system (professional version) for the Library of the NARS in collaboration with a most helpful in-house IT management team. The OpenKM is a versatile tool that helps put order into the chaos created by a big number of files and documents in file servers. Organizations produce piles of documents, images and other information electronically. The location of this information is a time-consuming task. Users tend to file papers and to save documents in folders on their own computers. Nobody knows what information is across the enterprise and what information is needed.
OpenKM uses standards and Open Source technologies to provide full document management capabilities including version control and file history, metadata, scanning, workflow, search, and more. It also allows the social activities around content to be used to connect people to other people, information to information, and people to information. OpenKM integrates all essential document management, collaboration and advanced search functionality into one easy to use solution. It provides a one-stop solution by managing both structured and unstructured information.
OpenKM builds a highly valuable repository of corporate information assets to facilitate knowledge creation and improve decision making. The result is improved productivity in the form of shared practices, greater cost efficiencies, better people relations, faster production cycles, shortened product time-to-market, and better decision-making.
The project was conducted under the oversight of the Hellenic Parliament and was part of an EU sponsored Twinning Program between the two Parliaments designed to aid the Parliament of Serbia in the road of Serbia becoming a full member-state of the EU in 2020.
