| 9 | ZOO Kernel is the heart of the ZOO. It is a powerful server-side C Kernel which makes |
|---|
| 10 | it possible to manage and chain Web services, by loading dynamic libraries and handling |
|---|
| 11 | them as on-demand Web services. The ZOO Kernel is written in the C language, but supports |
|---|
| 12 | several common programming languages in order to connect to numerous libraries and models. |

| 17 | ZOO Kernel works with Apache and can communicate with cartographic engines and Web mapping |
|---|
| 18 | clients. It simply adds the WPS support to your spatial data infrastructure and your |
|---|
| 19 | Web mapping application! |
