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.
DemoWave is a Web application for conducting referendums that allows anyone to propose a new referendum, minimizes the negative effects of people "spamming" the system with bogus referendums, and makes referendums where people disagree a lot take longer to go through. In addition, it can manage a set of laws and referendums on changes to those laws. DemoWave is intended for democratic organizations that need to decrease the bureaucratic load and increase the participation of their members in the decision-making process.
The ReliaFree Project is an alternative to commercial, proprietary reliability, availability, maintainability, and safety (RAMS) analysis software. The ReliaFree Project is an integrated suite of tools. Any number of analyses can be linked together such that an update to one module will result in all linked modules being updated appropriately. This approach provides a closed loop life-cycle with visibility into a product's performance throughout. The same database is used to store field failure data as is used to store design prediction information.
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.
