ZOO-Project 1.3.0 rc1 is out !

​See the related release page

Welcome to the ZOO Project

ZOO is a WPS (Web Processing Service) open source project released under a MIT/X-11 style license . It provides an OGC WPS compliant developer-friendly framework to create and chain WPS Web services. ZOO is made of three parts:

• ZOO Kernel : A powerful server-side C Kernel which makes it possible to manage and chain Web services coded in different programming languages.
• ZOO Services : A growing suite of example Web services based on various Open Source libraries. (get inspired !)
• ZOO API : A server-side JavaScript API able to call and chain the ZOO Services, which makes the development and chaining processes easier.

ZOO Kernel introduction

Powerful ZOO Kernel, that makes coffee

ZOO is based on a 'WPS Service Kernel' which constitutes the ZOO's core system (aka ZOO Kernel). The latter is able to load dynamic libraries and to handle them as on-demand Web services. The ZOO Kernel is written in C language, but supports several common programming languages in order to connect to numerous libraries and above all to simplify the Web service end-developer's job.

Use the ZOO Services and make your own

A ZOO service is a link composed of a metadata file (.zcfg) and the code for the corresponding implementation. The metadata file describes all the available functions which can be called using a WPS Exec Request, as well as the desired input/output. Services contain the algorithms and functions, and can now be implemented in C/C++, Fortran, Java, Python, PHP, Perl and JavaScript.

Easy implementation with the ZOO API

The ZOO API is a simple and concise JavaScript library designed to call and chain the ZOO Services easily, and adds the capability to define logic in the chaining of your ZOO Services.
