+= Exercise =
+
+You know everything now about writting zcfg matadata files and get short pieces of code in {{{service.c}}} or ogr_service_provider.py depending if you choosen C or Python programming language respectively.
+
+The goal of this exercise is to implement the following multiple geometries services :
+
+ * Intersection
+ * Union
+ * Difference
+ * SymDifference
+
+== C version ==
+
+Your are now invited to edit the {{{source.c}}} file you have created during this workshop to add the multiple geometries, using the following OGR C-API functions :
+
+ * [http://www.gdal.org/ogr/ogr__api_8h.html#5a271b5c7b72994120e7a6bbc7e7e5cb OGR_G_Intersection](OGRGeometryH, OGRGeometryH)
+ * [http://www.gdal.org/ogr/ogr__api_8h.html#f58f2cfbdb2497659d2eabea73d3b8a0 OGR_G_Union](OGRGeometryH, OGRGeometryH)
+ * [http://www.gdal.org/ogr/ogr__api_8h.html#497977bec6ecd9dade7a9694f776be64 OGR_G_Difference](OGRGeometryH, OGRGeometryH)
+ * [http://www.gdal.org/ogr/ogr__api_8h.html#d6dacf495617a230c6f19950bc415f17 OGR_G_SymmetricDifference](OGRGeometryH, OGRGeometryH)
+
+You can use the {{{Boundary.zcfg}}} file as example, rename the {{{InputPolygon}}} input to {{{InputEntity1}}} and add a similar input named {{{IntputEntity2}}}. You are invited to update other values in the ZOO Metadata File to set the proper metadata informations.
+
+== Python Version ==
+
+Your are invited to edit the ogr_ws_service_provider.py file you created during this workshop to add the multiple geometries using the following osgeo.ogr Geometry methods applied on the first Geometry instance :
+
+ * Intersection(Geometry)
+ * Union(Geometry)
+ * Difference(Geometry)
+ * SymmetricDifference(Geometry)
+
+You can once again use the Boundary.zcfg file as example, rename the InputPolygon input to InputEntity1 and add a similar input named IntputEntity2. You are invited to update other values in the ZOO metadata file to set the proper metadata informations.
+
+== Testing your services ==
+
+Once the multiple geometries Services are deployed on your local environment, please reload the zoo-ogr.html created during the previous section from your browser and test your brand new ZOO Services.
