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

Using ZOO Kernel as a Web Processing Platform

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

Note

Supported Languages

ZOO Kernel supports the following programming languages, and let’s you use them to create new ZOO Services from new or existing code:

Language ServiceProvider DataStructure Return
C / C++ Shared Library maps* M integer
Fortran Shared Library CHARACTER*(1024) M(10,30) integer
Java Class File HashMap integer
Python Module File dictionary integer
PHP Script File Array integer
Perl Script File   integer
JavaScript Script file Object or Array Array/Object

ZOO Kernel is a WPS Espresso Machine
