New to GIS programming so this might be a silly question. Is there a standard way to store/transmit how a GIS feature is to be displayed? So I can see there's loads of standard ways of storing tha actual GIS data, WKT, WKB, GeoJSON etc, but how should I store display information? e.g. I've got a polygon, it has a line width, line colour, colour, transparency, etc. How should this information best be stored that's technology neutral and preferably that's well understood by different systems?
There is SLD (Styled Layer Descriptor), which I think is mainly used in OpenGIS environments. ArcGIS might have some support for it, but I have never pursued that option myself.
