The goal of the X-itools project is to propose an alternative to products like Exchange or Lotus Notes/Domino. They are composed of several modules, and this project has been under development for several years. Modules include a shared public and private agenda, a flow-chart, task, and post-it manager, a visitors and associated badges manager, a password and history manager (with the ability to encrypt things other than passwords), a holiday manager (to manage public vacation days, illness periods, absence periods according to country profiles), a shared public and private address book, an incoming and outgoing phone calls manager, and a global management module.
Enzyme is an architecture for creating user-searching-user applications. Right now, it is primarily useful as a resume create/search and HR management system. However, it's potential uses are wide-ranging, and it offers PHP developers an alternative to relying on simple "keyword" searching systems.
XMLDB uses an RDBMS to persist arbitrary XML documents. Due to its storage mechanism, searching for and recalling documents is extremely quick. You can also perform XSL translation on documents with surprising speed. The library can be used in any program to store libxml2 documents. A PHP module is also included, making XMLDB into a complete three-tier Web application development suite.
xmltvdb creates a database from a set of xmltv listings and then provides a Web interface to view the TV listings in a grid format similar to many Web-based listings providers, but with user customization and no advertising. It supports explicit and bayesian classification of shows to highlight items you like and de-emphasize ones you don't.
Netinfo is a IP/MAC address locater for switched networks. It collects information from routers and L2/L3 switches and combines them to provide IP-MAC, IP-switch interface, and MAC-switch interface pairs. This makes it possible to determine the exact location of an IP or a MAC address in a network. It supports policy configuration and violation detection and can location duplicate IPs and IP address changes. It can also be used to monitor access to switch interfaces and stores a history of all collected information. Experimental support for automatic user lock-out in the event of violations is also included. It works with Cisco devices and is intended for use by NOCs and network administrators.
GNU EPrints is a solution for sites wanting to set up archives. By default it is configured to be an archive of research publications but can be easily altered. It is scalable and robust; all metadata is stored in UTF-8 rather than ASCII, and all "phrases" the system uses in user interaction are stored in an XML file for easy editing or translating. The system is built around Apache, mod_perl, and MySQL. Submissions are made via the Web and not entered into the main archive until approved by an editor.
