Welcome to the XMILE Discussion Forum

Post by Robert Eberlein » Wed Jul 31, 2013 6:04 am

Hi Everyone,

To recap quickly where we are. In 1995 Magne Myrtveit presented the paper "Models crossing the boundaries of tools" (http://www.systemdynamics.org/conferenc ... rtv170.pdf at the Tokyo conference. Then in 2003 Jim Hines coined the term SMILE (Simulation Model Interchange Language - Jim added the E for Emphasis I guess) in the Society Newsletter (http://www.systemdynamics.org/newslette ... g_2003.pdf). In 2005 Vedat Dyker and Bob Allen changed the S to X for XML in "Towards an XML Interchange Language for System Dynamics Models" (System Dynamics Review 21(4), 351-359.). Thus came the term XMILE (which I pronounce shmile) which was picked up by Karim Chichakly who has stuck with it (see for example "SMILE and XMILE: A Common Language and Interchange Format for System Dynamics" (http://www.systemdynamics.org/conferenc ... ICH385.pdf)presented at the 2007 conference).

Lots happened in between, but more is happening today. The XMILE standard is now before an international standards body (OASIS) with the expectation that an official standard will be approved in the next 12-18 months. Now is the time to make sure that the resultant standard is as good as it can be to move the field of system dynamics forward into the future.

To that end, we are asking members of the system dynamics community to put forward ideas and constructive criticism as the standard is formalized. The OASIS discussion forum archive (https://lists.oasis-open.org/archives/xmile/) can be viewed read only, with posting allowed only by OASIS Technical Committee members. This forum is open for all to post, and the two representatives of the Society on the OASIS Technical Committee (currently Len Malczynski and Bob Eberlein) will repost with attribution important ideas or criticisms from here to the OASIS forum.

The new standard will be based on the draft specifications for XMILE (http://www.iseesystems.com/community/su ... MILEv4.pdf) and SMILE (http://www.iseesystems.com/community/su ... MILEv4.pdf) (the underlying model equations) created by Karim.

Finally, just as points of contact, there is an ad-hoc committee of the System Dynamics Society devoted to reviewing and influencing this emerging standard. The committee members are myself, Len Malczynski, Magne Myrtveit, Ignacio Martinez, Nathaniel Osgood and Imrama Umar). If you have concerns that you do not wish to post on this forum please feel free to email any of us - we are all in the membership directory available to Society members on the web portal (http://www.systemdynamics.org/web.portal) if you do not know our emails.

To round off Bob's excellent summary of the state-of-play to date, it's probably helpful to provide back-links to the two major threads on XMILE on the Open Discussion forum:

Subject: "XMILE"

Subject: "Proposal for an OASIS XMILE Technical Committee"
