Ariadne is a Web Application Framework and Content Management System built with PHP. It allows you to build complex Web applications and sites with ease. It takes care of the mundane stuff like internationalization, security, user management, templating, data retrieval and storage, caching, and site management. It stores content in a structured object store that can be accessed through an extensive filesystem-like API.
The adventure PHP framework (APF) is a utility to implement object oriented and generic PHP Web applications. It allows the developer to create programs in compliance with approved software design patterns, and the code base already has answers to many everyday problems. The framework cannot be described as an application that only has to be configured, but rather as a technical basis and design guide for the design of software. Further, it introduced many concepts and efficiency tools already well known in the Java community.
XEO (eXtensible Enterprise Objects) is an agile development framework designed for creating Web applications built around Object Oriented concepts and Model Driven Development with Java. You model business entities (including their attributes and behavior) as XEO Models which are then processed by the framework's "Builder". This produces the application's supporting structures such as database tables (to persist data) and Java classes (providing object-relational mapping and behavior). Development is supported by an Eclipse plugin called XEOStudio.
UDIG (User-friendly Desktop Internet GIS) is a spatial data viewer and editor with emphasis on the OpenGIS standards for Internet GIS, the Web Map Server and Web Feature Server standards. It provides a common platform for building spatial applications with open source components.
