For what is related to the detector software, we indicate 6 areas (tracking, detector description, event display, simulation, test data analysis, construction & test software) separately interacting with the GLAST core (we don't see the need for a structure labeled "Italy" for interactions with the outside world, while we strongly see such a need for our internal coordination, test of software, exchange of information etc.). We think that next year such areas should evolve into the building of the software for physics analysis.

For each area we individuate subtopics with a convenor and a team. For each subject, milestones correspond to the finest granularity.

1) Tracking :
    1a) Test of algorithms (Kuss, Omodei, Lumb, Spandre, Latronico, Mazziotta, Loparco, Longo, Morselli, Pittori)
    1b) Charge sharing (Mazziotta, Lumb, Spandre, Latronico, Loparco, Gargano, Tosti, Lubrano)
    1c) TOT  (Mazziotta, Lumb, Spandre, Latronico, Loparco, Gargano, Tosti, Lubrano)
2) Detector Description
    2a) C++ generic model for the XML geometry description (Favretto, Giannitrapani) - completed; now in testing phase
    2b) GEANT4 client of the generic model (Longo, Favretto, Giannitrapani) - completed; now in testing phase
    2c) Digitizations in the tracker (Giglietto, Brigida, Latronico, Spandre, Lumb, Cecchi, Lubrano) -interacting with all subitems of 1) and with 2b)
3) Event Display and graphics
    3a) Event display (Giannitrapani, Favretto, Lumb, Spandre)
    3a1) Generic Event display (Giannitrapani, Favretto) - prototype to be completed in october
    3a2) Baloon Event display (Lumb, Spandre) -  june, then goes into 3a1)
4) Simulazione : = 4b)
    4a) Validazione G4 - fisica (De Angelis, Longo, Giannitrapani, Lubrano) - to be completed in october
    4b) General GLAST simulation (Longo, De Angelis, Giannitrapani, Favretto, Cecchi) - prototype to be completed in december
    4c) GAUDI integration (Brigida, Longo, Giannitrapani) - to be completed in december - at least in prototype
5) Analisi dei dati di test
    5a) Validazione G4 con dati di test esistenti (Lubrano, Cecchi, Cestellini) - to be completed in august, interact with 4a) & then with 4b)
    5b) Pallone (Kuss, Omodei, Lumb, Spandre, Latronico, Cestellini)
        5b1) validazione G4 (data simulated by Tune & C)
        5b2) test algoritmi tracking/background rejection (interacting with 1a)
6) Construction and test software
    6a) Construction Database (Latronico, Spandre)
        6a1) MSAccess prototype - in use for evaluation - to be finalized
        6a2) Cristal prototype - under construction - to be implemented by end of june
        Milestones: get a first evaluation for the august collaboration meeting
    6b) Tracker alignment algorithm (Brez, Lumb, Spandre, Kuss) to be developed for tower assembly (sometimes in 2002)
    6c) Calibration and test software (Lumb, Spandre, Kuss)
        6c1) local implementation of tracker reconstruction software
        6c2) test of tracking algorithms (cosmic rays - without CAL - interacts with 1a) ?
