CHEP'07 Theme:

The theme of the conference will focus on the processing of HEP data at all stages, from the high level triggers that run on farms of CPUs situated close to the experiment through to the final analysis that use resources distributed worldwide.

We expect to draw on the experience from running experiments and also to review the status of new studies of the distributed computing models being made in preparation of the LHC experimental programme.

JAIDA, JAS3, WIRED4 and the AIDA tag library - experience and new developments

JAIDA is a Java implementation of the Abstract Interfaces for Data Analysis (AIDA) and is part of the FreeHEP library. JAIDA allows programmers to easily create histograms, scatter plots and tuples, perform fits, view plots and store and retrieve analysis objects from files. JAIDA can be used for batch processing or with a GUI. JAIDA reads and writes AIDA compliant files and can access data from ROOT, HBOOK/PAW or SQL databases. Access from C++ uses the AIDAJNI adapter. JAIDA includes JMinuit, a complete port of Minuit to Java. JAS3 uses JAIDA providing a full featured GUI.

WIRED4 is a generic Event Display displaying 2D/3D views of HepRep events. As plugin module in JAS3 it has full interactivity, such as scaling, rotation and hiding. Recent extensions handle picking of elements to show detailed information and interactive cuts to hide details.

The AIDA tag library (AIDATLD) is an open source suite of custom tags that provide access to JAIDA from J2EE applications and JSP pages. It can dynamically create high quality physics and astronomy plots and providing access to histograms and Ntuples stored in any AIDA store, including ROOT files via (x)rootd, from web applications.

This software is used by several experiments and collaborations, including BaBar, GLAST, and Geant4. Experience of using this software and new developments will be presented in the talk. In particular, a wide ranging suite of web applications developed using these tools for the GLAST experiment will be described.

    Title:

    JAIDA, JAS3, WIRED4 and the AIDA tag library - experience and new developments

    Abstract:

    JAIDA is a Java implementation of the Abstract Interfaces for Data Analysis (AIDA);
    it is part of the FreeHEP library. JAIDA allows Java programmers to quickly and easily
    create histograms, scatter plots and tuples, perform fits, view plots and store and
    retrieve analysis objects from files. JAIDA can be used either in a non-graphical
    environment (for batch processing) or with a GUI. Files written with JAIDA adhere to
    the AIDA IO standards and can be read by any AIDA compliant analysis system. JAIDA can
    also access data from ROOT, HBOOK/PAW or SQL databases, and can be used from C++ via
    the AIDA "C++ to Java" adapter (AIDAJNI). JAIDA now includes JMinuit, a complete port
    of Minuit to Java. JAIDA is used internally by JAS3 which provides a full featured GUI
    in addition to the above functionality.

    WIRED4 is a generic Event Display which handles both 2D and 3D views of HepRep events.
    It runs as a plugin module in JAS3 and gives the user full interactivity on any of the
    views. Apart from scaling, rotation, hiding it has recently been extended to handle
    picking of element to show detailed information and interactive cuts to allow the user
    to hide unnecessary details.

    The AIDA tag library (AIDATLD) is an open source suite of custom tags that provide access
    to JAIDA from J2EE applications and JSP pages. It provides the ability to dynamically
    creating high quality physics and astronomy plots, as well as providing access to
    histograms and Ntuples stored in any AIDA store (which includes ROOT files via rootd
    or xrootd) from web applications.

    This software is currently used by several experiments and collaborations, including
    BaBar, GLAST, and Geant4. Experience of using JAIDA, JAS3, WIRED4 and AIDATLD in experiments,
    as well as a description of new developments will be presented in the talk. In particular
    we will describe a wide ranging suite of web applications developed using these tools
    for the GLAST experiment.

    Mark,I'me not sure if word count is strictly enforced, but
    CHEP requires an abstract to be be between 150 and 250 words,

    here we have 322.

    Maybe we can shorten the first paragraph?
