Hi folks, I have put an update of the whiteboard drawing from the workshop on May 15 at: http://www-rnc.lbl.gov/GC/meetings/14may98/figures.ps http://www-rnc.lbl.gov/GC/meetings/14may98/figures.pdf There are two pages now, the second is a couple simplified use-cases (load tag, and execute). Again, let me know if you have any comments or corrections. Thanks, Doug
