System Dynamics Markup Language

Dear friends,

While building ""Interact"" (http://home.utad.pt/~tasso/interact), we have
the necessity to define a specific Document Type Definition (DTD)
protocol for use with its XML I/O file. Simply speaking, this DTD will
define the tags to be used in the XML file, so it captures all System
Dynamics entities and operations. Here is an example of how a stock may
be defined (more details in the ""Interact"" Software Development Manual,
online):

---
<object name=""stock_1"", units=""m3"", type=""stock"", status=""monitor"",
target=""0..1"", comments=""the main stock"">
<value> init + (dS/dt)dt </value>
</object>
---

Building such a DTD is simultaneously an opportunity for defining a
special markup language for System Dynamics (which would be SDML -
System Dynamics Markup Language). This is why I am making this call to
the SDS community, for feedback and ideas.

There already exist two specific XML standards, based on the
definition of specific ""standard"" DTDs: one for genealogy (GedML) and
the other for chemistry (CML) - i.e. what elements chemical equations
must have, and the same for genealogic trees. System Dynamics could come
next! Can we do it?

Best regards,
Tasso
