hi, a group of us at indiana recently wrote a small paper with a 10,000ft overview of ogsa and a list of grid deployments (not the full survey that craig was looking for). we also look at some things that are often found on grids, but by themselves may not be a grid in the ogsa wordview. we call them gateway frameworks (a term taken from the teragrid project). if you are interested the paper is here: http://www.extreme.indiana.edu/~gannon/SOAs-for-Grids2finalV2.pdf i welcome any comments, esp. if we incorrectly characterized ogsa or one of the grids. dennis
