ROI Proposal September 2010
Information on the proposed ROI Model for the next available Major release.
This moves the ROI model into 3-dimensions by pushing the Z value from the Shape level down into the geometry objects themselves (e.g. Point now has X, Y, Z).
This requires the removal of Polyline and Path. They are replaced with a Vertex Array geometry object. It should be possible to upgrade Polyline objects as part of the XSLT transform. It seams unlikely that Path can be upgraded in this manner, more complex code would be required.
Polyline and Path are being marked as Deprecated in the April 2010 release of the schema. Details of that ROI model is available here.
The diagram below shows an overview of the current proposal, it is not set in stone and we would welcome comments and suggestions.
