Dear Sirs, In the DEISA accounting system we make use of the OGF Usage Record recommendation, als described in the Experiences document about OGF UR1 document. For extensions and other accounting projects we need a format for aggregate or summary records where we would like to adhere to standards as much as possible. When searching for standard ways to represent aggregate records I came across the attached documents. I was wondering if there were any more recent information about the development of Usage Record Format 2 and more specifically the format for aggregate or summary records. If there any newer drafts or developments in this area, please let me know Best regards, -- Bart Heupers, HPCV Advisor, 31 (0) 20 592 8071, Science Park 121, 1098 XG Amsterdam
