• ARC/GFAL comparison table
  • Jon and David filled out ARC part, GFAL should be checked
  • Core GFAL should be written in C - could be problem for using ARC DMC in GFAL

  • gLite tries to use SRM code from ARC
    • investigate the possibility of using ARC plugins in connection with GFAL
    • Zsolt will check DMC documentation
  • ARC tries to create a GFAL plugin to make it possible to use the protocols supported by GFAL
