- LCG Blueprint (19dec02 - Caltech Pasadena, CA) Still Early in the Process Both projects (PI & SEAL) are only weeks old. Explicit realization that the two project leads will need to define the boundary and responsibilities. I do not have info on PI/LCHb/ALICE/CMS talks No ATLAS enthusiasm for another Visualizer or Histogramming project. Vincenzo has expressed interest in the GANGA project and design. —Talk next year. My take: —SEAL - up to and including the "Presentation Layer" (see my Python talk) —PI - Task Layer and above. —Usability layer likely to fall on SEAL side of fence.
