This page is the hub for SimileXMLv1, the first version of a Simile XML language.   It is reasonably faithful to the original Prolog structure, but with some alterations.

This is the home page for SimileXMLv2.

SimileXMLv2 involves a major re-design of the data model for representing Simile models.

The basic idea is to enable a composite model to be built up by cut-and-pasting the XML for one (child) model into another (parent) model (or, equivalently, adding an XInclude element into the parent model).

This is the home page for SimileXMLv3.

SimileXMLv3 is intended as a bog-standard XML representation of Simile models, with a direct, one-to-one relationship between the parts of the Prolog clauses and the XML elements and attributes.  

The aim is to provide a robust XML-based language which can provide guaranteed conversion in either direction (including round-tripping).   This aim can be met with more profound changes to the syntax or underlying data model, but this would require more work to come up with the new design, and to ensure that it works under all circumstances.
