Essential Management provides a project management system for organizing and writing technical documents.

Essential Management is a multi-user project management system for managing intricate and complex information. Its initial purpose was to allow software development teams to create, maintain, track, and store project requirements on a multi-project basis in a multi-user environment. It has now become more abstract in the type of data it can maintain, allowing the easy addition of new data models and other expansions. Information can be stored in any of several database management systems, and can take advantage of a networked DBMS.

The first and most important feature of the application is that data is stored in a central data repository managed by some database management server; initially PostgreSQL fills this role, but support for others are growing. The repository is fully searchable. An alternative data storage format exists in the form of a locally maintained XML file if the user wishes to use it.

One of the key features Essential Management was designed around is the ability to define and maintain relationships between requirements. Using the software requirement model as an example, our application allows users to define projects; each project is composed of zero or more root requirements, which are typically business level requirements. Each business requirement has zero or more sub-requirements, which either refine the parent business requirement or dive into the functional requirements which allow the business requirement to be achieved. This tree continues to branch and grow deeper until the most basic level that the user wishes to define is reached.

In addition the relationship between parent and child requirements, relationships can be defined between requirements not in the same branch. These relationships may have any meaning the user wishes to define and can be unidirectional or bi-directional.

Essential Management implements the concept of user level permissions, which provides a small measure of security for the projects and their requirements. Additionally, creation of and changes to requirements can be traced to the user who initiated the action.

Finally, the application provides a means to track changes made to requirements during their lifetime so it is possible to determine when a change was made, what information was changed and who edited the requirement.

Network Tracker and Management is a Web-based network management application.
Network Tracker and Management can store information about all of your network devices, and allows you to track all changes and updates made to the device.
Having this information readily available will enhance your ability to troubleshoot network problems.
Enhancements:
- The documentation was updated to include more details on the setup of the database for the network tracking system.

openQRM Plug-ins is a collection of community-supported plug-ins that enable openQRM to manage other enterprise and open source software.
openQRM is designed to deal with all sorts of failures automatically, thus preventing interrupts because of unexpected events.
Implementing openQRM greatly improves the reliability of the x86 data-center.
openQRM is an open source systems management platform which integrates with existing components in enterprise data centers to create scalable, highly available and customizable infrastructures.
openQRM is derived from a proven commercial product and distributed as an open source project through SourceForge, using a modified Mozilla Public License.
openQRMs architecture extends to and embraces other existing data center technologies through "plug-ins."The openQRM project team has created a number of plug-ins for broadly-used open source projects and proprietary solutions, and seeks to recruit community members to assist in additional plug-ins.
openQRM leverages the proven technologies of PXE and NFS along with storing images on central storage to effectively manage the data center.
The project team aims to set the standard in data center management by continuing to provide a "premiere" enterprise-grade project for automating IT infrastructure, and by embracing other technologies through increasing our offering of plug-ins.
OpenQRM.org is the best destination for our projects community to share ideas and innovations. Contributed by Qlusters, openQRM.org offers a range of support and information services to benefit all users of openQRM, including implementation advice, user forums and customer feedback.
Enhancements:
- The lvm-mgmt plugin was ported to openQRM 3.1.4 and support for remote storage-server was added.
