Syntax

A URL-based (not in the query string) RPN notation.

For example:

http://iridl.ldeo.columbia.edu/expert/SOURCES/.NOAA/.NCEP/.CPC/.GMSM/.w/5/add/

SOURCES .NOAA .NCEP .CPC .GMSM .w (the OPeDNAP data variable)

5 add (the constant 5; the operation desired)

http://iridl.ldeo.columbia.edu/expert/SOURCES/.NOAA/.NCDC/.ERSST/.version2/.SST/X/(170W)(120W)RANGE/Y/(5S)(5N)RANGE[X/Y]average/ (The actual URL must be encoded. See the link contents.)

SOURCES .NOAA .NCDC .ERSST .version2 .SST (The OPeDNAP data variable)

X (170W) (120W) RANGE (A range in X of the data variable's underlying grid in world coordinates)

Y (5S) (5N) RANGE (A range in Y of the data variable's underlying grid in world coordinates)

[X Y]average (the dimensions to be operated on; the operation)

Benno -- Is there also an index notation for the ranges? If Y did not appear in the [X Y] then the average would be a line in Y from 5S to 5N, right?
