I give here a sample of using Chaining in ZOO Kernel (and in WPS in general). Since you can use a reference, you are able to use the result of another process.</div><div><br></div><div>For instance, you could run SymDifference process using a GML entity as input 1 and for the second : the result fetch by a Buffer process for the same entity.
