I'm interested in working on capabilities along these lines. Are there existing RFCs that touch on this? If not, perhaps one should be created.
This overlaps some configuration ideas I've been mulling over. From the original comment here about internal vars being handy for "/when the same layers are re-used for several customers who like to have a bit different styling for the same source data/" it occurs to me that a matrix or some other constructs more complex than a flat list of internal variables might be called for -- provided they don't turn the mapfile and internal mapserv into spaghetti.. Jukka Rahkonen (have I ordered your name properly?), do you want to start an RFC on this? To anyone -- would this conversation typically migrate over to 'dev' ? Robert Hollingsworth I agree that this is a request that comes up often. As usual we'd just need someone to lead the effort.
