Domain Specific Languages for GIS?
When I first heard about domain specific languages (DSLs) a couple of years ago, I figured there would soon be folks really digging into this for GIS. The discussion here about GIS scripting is interesting, but would be more helpful to have a DSL discussion. I guess ESRI’s modelbuilder is a DSL IDE, looks similar to the one discussed here. I always liked the way unix allows you to chain commands together into one long single command, piping the output of one command as the input of another. No IDE needed – its all command line. Seems like unix-friendly DSLs would be a natural step for the opensource folks. OGC mentions DSLs here as “GML Application Languages”, but I can’t really follow this to anything concrete.
