= Welcome to the ZOO Project  =

ZOO is a WPS (Web Processing Service) open source project released under a [/../site/ZooWebSite/ZooKernel/Download#ZOOKernelMITX-11License 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:

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

= 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 [/../site/ZooWebSite/ZooKernel/Introduction 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 [/../site/ZooWebSite/ZooServices/Introduction ZOO service] is a link composed of a metadata file ([wiki:ZooWebSite/ZooServices/ZCFGReference .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 [/../site/ZooWebSite/ZOOAPI/Introduction 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.
