Module Name: IRIS 0.4
Release Date: February 2007
Organization(s): SRI International

Brief Description:
Release 0.4 is released to the public under an LGPL license. At this point, IRIS is still considered to be a fairly early stage research prototype (by no means a commercial product). However, it should be stable enough for use by a motivated user, and should provide enough of a framework where programmers can begin integrating with it.

IRIS is being developed as a small part of the CALO project. As such, we will try to be responsive to the open source community (particularly those who are using IRIS for machine learning purposes), but please understand that we have limited bandwidth..

What's New in 0.4:

• Integration of Pellet - IRIS has now a java-based OWL DL reasoner which supports advanced reasoning.
• Keyword filter added to IRIS Data Applications - this UI feature helps filter out relevant information in large volume of data.
• Various bug fixes to release 0.3

Known Issues:

The most important issues to know about are:

• PDFs can crash IRIS (#IRI-351): If you have not upgraded to Acrobat 7.0, opening a PDF file can freeze IRIS.
• Speed (#419, #464, #467): Installing IRIS is slow. IRIS is very slow on startup the first time, only a bit faster subsequent times, and during use, has functionality that needs to be dramatically optimized.
