Subject: Latest Draft of ISO/IEC 15909 for comment From: Jonathan Date: Sat, 28 Oct 2000 18:07:54 +0930 Dear Members of WG11 and Petri net experts. At last, I have what I believe to be very close to the final version of ISO/IEC 15909 High-level Petri Nets - Concepts, Definitions and Graphical Notation. I have incorporated all of the comments from the FCD round, and have also picked up on some earlier comments, particularly from the UK (Dan Simpson) in order for the standard to be more consistent. This has meant introducing the notion of step in clause 7 for the HLPN Graph, as it was introduced in clause 5 (Semantic Model) but not followed through in clause 7. I am hoping that I have picked up most of the inconsistencies between the different parts, that got introduced with the changes - but please proof read carefully particularly clause 7 (7.4 and 7.5). I have also updated the Biblio, and arranged alphabetically. Are there any references that should be added? Many thanks to Mat Farrington, one of my PhD students for helping with a lot of mechanical processing in particular getting the figures consistent across the body of the standard and the tutorial, so that they have the same look and feel. I would like to finalise this draft before December. I therefore request that you send me your final comments on this by 18 November 2000. If I receive no comments by then I shall assume that you are happy with the current draft to be sent on to SC7/JTC1 for FDIS ballot. Best wishes - Jonathan
