WEEP Version 1.0

From Wiki

Contents

Intention

WEEP 1.0 is the first official release of the WEEP project and intended to give interested users a first glance at the WEEP enactment service. This version does not emphasize any special features but should allow the user to test very basic Grid/Web service invocations. The goal is to show that architecture and concepts work and to get feedback about which activities are desired for next versions and which existing ones have to be improved.
