Intro

This project is intended as an experiment and probably should only be used by those who like to dig around code. For more information on the ideas behind CarrierWave, see this post.

In a nutshell, CarrierWave is a container for adaptive object models. You supply the business objects, CarrierWave provides:

• A code generator for client side data objects structurally mirroring server side business objects type hierarchy
• Pluggable binding between client and server (over RMI, EJB, or locally in same process space)
• Pluggable persistence and logging layers
• Pluggable query mechanism
• Zero-configuration externalization and internalization of server state into and out of XML (or any "custom" format)

What does this mean to developers and the development organization?

It means;

• They can use fine to coarse grained objects in the business layer and their semantics are exposed to the client layer. 
• Client and server side developers will have an architecturally enforced layer of isolation. 
• Coupling to a particular persistence implementation can be deferred until the business object design and implementation has stabilized. 
• Single application implementations can be easily reconfigured and deployed to execute not only within a single process space to but over multiple processes and machines using existing distributed systems facilities like EJB, JMS, or WebServices. 
• They can invoke queries against the business layer using a pluggable query syntax that may be optimized on the server during final development iterations. 
• They can apply initialization scripts to bootstrap server state, or to interact via the command line with server business objects during maintenance or testing.

This overview should provides additional details behind the implementation of CarrierWave.

Examples

Friend of a Friend (foaf)

You can now download a simple self contained example from the downloads page. You do not need to download or compile the CarrierWave distribution.

After uncompressing the archive, type 'ant' in the cw-foaf-ex directory. 

When the build completes, type 'xterm -e ./bin/rmi.sh &' to start the server.

The readme.txt file has details on how to initialize the state of the running 'foaf' server, change server state, and to use the simple 'foaf' client for measuring the 'social distance' between two parties.
