BSF4ooRexx is a Java language binding for the scripting language ooRexx. It allows ooRexx programmers to directly use the Java Runtime Environment (JRE) libraries. It allows, for example, implementation of Java methods in ooRexx and callbacks from Java to ooRexx. It camouflages Java so that it resembles ooRexx by being dynamically typed and caseless. BSF4ooRexx comes with built-in support for programming OpenOffice.org/LibreOffice.org and allows ooRexx to be used as a macro language.
KeyValue is a cross-platform library for making C++ objects accessible through LibreOffice Calc, Excel, and other front-ends. This can enhance the experience of spreadsheet users by providing an object model and a handy key-value based interface. Actually, KeyValue does more than just help creating spreadsheet functions. The object model allows end-users to build C++ objects through the front-ends. These objects are stored in a repository for later use at the user's request. Additionally, KeyValue provides a set of services to effectively use these objects. The library is named after one of its main features: the key-value based interface. Parameters are passed to functions (or, more precisely, processors) through key-value pairs, in contrast to the standard positional interfaces of LibreOffice Calc, Excel, C/C++, etc.
Due to C portability, OpenOffice.org's usual middleware, Universal Network Objects (UNO), could not be designed object oriented. With NOA-libre you can still access UNO, but also the NOA-libre object oriented layer atop UNO. Being based on UNO, NOA-libre is network aware, meaning that you can use it to have your local office installation execute some commands, or an OpenOffice.org installation anywhere on the world, provided you have a appropriate network connection and privileges. With NOA-libre, you can: embed OpenOffice.org windows in your Java applications or applets; remote control OpenOffice.org windows on your desktop, over the network, or "headless", i.e. only functional without visible output; and/or extend OpenOffice.org by writing Java plugins. NOA-libre is compatible with OpenOffice.org and LibreOffice, easier to deploy than the usual UNO-only Java applications, and allows you to interact with various OpenOffice.org components (but is by far most commonly used with Writer and Calc).
OpenTBS is a PHP tool that helps you to make OpenOffice and MS Office documents using templates. You first design your template using OpenOffice or MS Office, and then OpenTBS merges it with data that you supply from PHP code and databases. It has facilities to manage pictures. The resulting documents are saved to file, served for download, or returned as a string. In fact, OpenTBS can merge any OpenDocument files, any OpenXML files, and any XML files compressed in a Zip archive. No extra exe file is required and it makes no temporary files, since all work is done in memory. OpenTBS is based on the TinyButStrong template engine.
Ipt_fw is a firewall for Linux based on iptables. It is designed for client systems. Ipt_fw outputs a shell script containing iptables commands, so inspection of the settings it creates is easy. The configuration files are made in LibreOffice（OpenOffice）Calc. Making of the firewall and a machine using the firewall are separated. It allows you to set the user level and features detailed logging, IP address blacklist management, and iptables integrity.
