Re: XMILE

Tom, that is good news! Here are the specs I tried to post earlier (thank you, Bob!).

Re: XMILE

Hi Magne, Bob Eberlein and I spent quite a bit of time refining the spec last fall. I have been remiss in not posting the new version, but I expected it to change further. It hasn't, so I will now post what we arrived at a year ago. [Unfortunately, the forum is not letting me post it.] The spec is n...

Re: XMILE

Hi Bobby, thanks! It has taken a lot of hard work and I wish I could say it was finished. Representatives from a number of companies (isee systems, Ventana Systems, PowerSim Software, XJ Technologies, and Forio Business Simulations) met at the conference to discuss implementing this across a number ...

XMILE

I promised an update to the XMILE documents and here it is just in time to discuss at the ISDC conference. I have said many times that this is getting implemented in iThink and STELLA. After many delays, I can now honestly say we have started. We expect full level 1 support and partial level 2 suppo...

Re: Open Source SD software development

Maybe... I also abhor redundancy. Remember I separated out SMILE from XMILE for a reason. XMILE is a representation of SMILE. SMILE is intended to be a package-neutral definition of the stock-flow language that every package ought to support. Insofar as it falls short, I believe we ought to be looki...

Re: Open Source SD software development

The authors are me. I started with DYNAMO as already stated, not STELLA, and then blended in things from Vensim and Powersim, though I am sure I missed quite a lot. It was meant to evoke discussion and provide enough to be expanded by other interested parties. As Bob Eberlein pointed out earlier, a ...

Re: Open Source SD software development

I couldn't agree more and wish I could have said it as eloquently.

Re: Open Source SD software development

Magne said: The proposed SMILE/XMILE language seems to make the false assumption that the features of modern modelling platforms with support for SD modelling can be arranged along a line from the basic constructs to increasingly more advanced features. There is no such assumption in SMILE. The lev...

Re: Open Source SD software development

I think it is important to remember that the SMILE document was designed as a base set of capabilities that can then be expanded later. It is not, nor was it ever meant, to encompass all features in all SD software applications. I think that is an impossible task. When Bob Eberlein and I first discu...
