Alpha release anouncement:

QARE is now complete, except for plugins (jar file extensions), though testing has been minimal. And 
documentation is currently limited to the API.

QARE is an XML/Java Portal, providing an easy-to-use platform for processing XML over HTTP--QARE runs as 
a simple Java Servlet. (QARE is pronounced "care".)

QARE can handle any number of different markup languages. The type of markup language is specified in the file 
info portion of the URL used to invoke the servlet.

QARE processes POSTed XML documents by converting them into agents. These agents then perform the request 
specified by the XML document and respond with an object which is converted back into XML and
returned to the requestor.

These agents are safe and virus-proof, as they are built using code resident on the server. Agents are composed 
using the incoming XML documents, which are validated prior to invoking the agent. With appropriate content
validation, incoming documents are constrained to only those which create proper agents.

While most agents are transitory, agents can also be persistent. A snapshot facility is provided so that persistent 
agents can be restarted after the web server has crashed.

Local agent/agent communication is supported, so that transient agents can make use of the services provided by 
persistent agents. This makes QARE extensible through the use of appropriate persistent agents.

And while plugins (jar files) are not yet supported, agent/agent communication uses the Quick Transcribe capability, 
allowing each agent to use its own classes for messages passed between agents.

QARE is Open Source, and licensed under LGPL.
