subPersistence is an abstract, light-weight yet flexible framework for working with O/R persistence mappers. It provides for independence of a specific O/R mapper such as Hibernate or Castor.
While you can use Hibernate or Castor (or other O/R mappers) directly, coupling your application too tightly to those can be a bad thing. subPersistence makes it easy to switch underlying O/R mappers, thereby decoupling the application layer from those.
It abstracts away differences between the mappers, while still making it possible to use their specific features if needed.
Enhancements:
- This version updates to Java 5 features such as Generics and is the first version to require Hibernate 3.

Persistent::DBI is an Abstract Persistent Class implemented using a DBI Data Source.

SYNOPSIS

### we are a subclass of ... ###
use Persistent::DBI;
@ISA = qw(Persistent::DBI);

ABSTRACT

This is an abstract class used by the Persistent framework of classes to implement persistence using DBI data stores. This class provides the methods and interface for implementing Persistent DBI classes. Refer to the Persistent
documentation for a very thorough introduction to using the Persistent
framework of classes.

This class is part of the Persistent DBI package which is available from:

http://www.bigsnow.org/persistent
ftp://ftp.bigsnow.org/pub/persistent

Before we get started describing the methods in detail, it should be noted that all error handling in this class is done with exceptions. So you should wrap an eval block around all of your code. Please see the Persistent documentation for more information on exception handling in Perl.

Speegle Define is a Firefox extension that gives a spoken definition of a word using Speegle Speech Technology. You highlight the word you would like explained with highlight left click on any internet page you are reading.

Right click and choose "Audio Definition" from the pop up menu and its definition will be read back to you in English through your speakers or headphones.

Demokritos is a server implementation of the Atom Publishing Protocol.
Demokritos also provides a library that can be used for the development of other Atom-related applications.
Usage:
To run a test server, cd to test directory and run test_server.py
client_test.py in the same directory will run through a sequence of tests on this.
Enhancements:
- Duplicates are now handled in URI minting.
- A feeds updated property after a removal of an entry is now current datetime (not that of the latest entry).
- Posts missing a media type now throw an exception.
- A bug where entry collections were being retrieved from the persistence layer as media collections has been fixed.

Arianne is a multiplayer online games framework and engine to develop turn based and real time games.

It provides a simple way of creating games on a portable and robust server architecture. The server is coded in Java and uses Python for your game description, provides a MySQL backend and uses an UDP transport channel to communicate with dozens of players.

Our reference client engines are coded using Java and the C language in order to achieve maximum portability.

Arianne has been in development since 1999 and has evolved from a tiny application written in pseudo-C++ to a powerful, expandable but simple server framework, running on the Java platform, and a portable client framework, written in bare C to allow total portability of ariannes clients. Ariannes server is totally client agnostic.

Since the beginning, the key concept at the heart of Ariannes development has been KISS: Keep it simple, stupid!

Arianne games are playable. It now hosts several games:

* a multiplayer Gladiators fighting game
* a multiplayer Pacman game

All our efforts are supported by ariannes server: Marauroa.

Marauroa is completely written in Java using a multithreaded server architecture with a UDP oriented network protocol, a MySQL based persistence engine and a flexible game system. The game system is totally expandable and modifiable by game developers and is able to run Python scripts defining the games rules.

Marauroa is based on a design philosophy we called Action/Perception. Each turn a perception is send to the clients explaining what they currently perceive. Clients can ask the server to perform any action in their name using actions. Marauroa is totally game agnostic and makes very little assumptions about what are you trying to do, allowing a great freedom to create any game type.

Bugs are facts of life, they just happen.

On Arianne we care about code quality so code is fully tested using Test Units with JUnit and cppunit, so all modules are tested for most common cases, allowing a better quality software to be deployed.

The name originated from the Greek name Ariadne. (Latin; Arianna and from French; Arianne). Ariadne is a famous character in Greek mythology. She was the daughter of King Minos of Crete and she was in love with Theseus, the Athenian hero who killed the Minotaur ( a half human, half bull creature).

Theseus married her, however, then later left her alone on the island of Naxos. Ariadne later married Dionisos the God of Wine. The name Ariadne originates from the ancient Greek words ari which means intelligent and adnis which means pure (as in a virgin). Hence, the daughters of the Romans and Greeks where often called by this name.

Cayenne is a powerful, full-featured Java Object Relational Mapping framework. Cayenne project is open source and completely free. One of the main Cayenne distinctions is that it comes with cross-platform modeling GUI tools.
This places Cayenne in the league of its own, making it a very attractive choice over both closed source commercial products and traditional "edit your own XML" open source solutions.
Enhancements:
- This release fixes a number of bugs in 1.2.

databeans is a fully object oriented (not relational) persistence framework for Java, based on the use of the JavaBeans accessor methods to read and write data on disk instead of in the classes instance fields.
Main features:
- based on the use of the javabeans accessor methods to read/write data on disk in place of in the classes instance fields
- distributed (through RMI)
- transactional (with the 4 ANSI isolation levels supported)
- garbage collected (backed by an on-disk heap "heapspace")
- with persistent versions of the Collection classes
Installation:
Extract the archive into any appropriate directory on your hard drive. It will create a "databeans" directory with the following contents:
build.xml
api
[api documentation as generated by javadoc]
bin
databeans_admin
databeans_admin.bat
databeans_export
databeans_export.bat
databeans_import
databeans_import.bat
export.bsh
import.bsh
mkheapspace
mkheapspace.bat
mkheapspace.bsh

The most interesting part for now is the file getting_started.txt located in the docs/ directory. It will guide you through running a sample application (which is located in the sample/ directory). That done, go on and read the manual (below) for a complete view of the products features.
