Hello all, I just uploaded a a few versions of the NML schema. http://forge.gridforum.org/sf/go/doc15481 Version 1 and 3 are the same, and the schema that Jeroen created about a year ago. Version 4 contains the modifications that were discussed at the last OGF and on the mailing list. Version 5 is a proposal created by Martin Swany, Jeroen van der Ham and myself two weeks ago. The major change is to make all relations an explicit object. Tomorrow at the conference call we hope to discuss with you if this is a change for the better or not. Regards, Freek Dijkstra PS: Sorry that the version comment field is empty in GridForge; GridForge is not really intuitive.
