Title : JAS3 -  current status and prospects.
Authors : A. Johnson, M. Donszelmann, J. Perl, V. Serbo, M. Turri , SLAC
Abstract : 
JAS3 is a general purpose, open-source, data analysis tool.  This talk
will describe current status and give an overview of the features and
design of JAS3.  JAS3 builds on several open-source projects and so is
able to leverage a large amount of existing code. The program uses a
highly modular component based framework which allows it to be
customized for a particular problem domain by addition, replacement or
removal of modules. The JAS team is also an active partner in the AIDA
working group, and JAS3 makes extensive use of the AIDA interfaces. JAS
is currently used by Babar, Glast, US Linear Collider group, and many
other individuals and groups. Features of JAS3 include: 

- Easy to learn GUI for performing common analysis tasks (plotting,
  ntuple-analysis, fitting etc.). 
- Support for a variety of scripting languages (pnuts, jython, etc.),
  and for writing Java "analysis modules". 
- High quality print output and export of plots in a variety of formats
  including PS, EPS, PDF, SVG, GIF, PNG. 
- Fitting (binned or unbinned) using an extensible set of fitting
  methods and optimizers. 
- Able to read data in a variety of formats including: SQL databases and
  text-files. 
- Customizable event display based on WIRED4.
- Support for client-server, distributed, and Grid based interactive
  data analys is. 
- Support for online monitoring and control applications.
