ZOO-Project
================================================================================

WPS Server
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

ZOO-Project provides a developer friendly Web Processing Service (WPS) framework for creating and chaining Web Processing Services.
A WPS provides web access to functions which run spatial algorithms.
ZOO-Project supports many programming languages and comes with two demo applications using simple
spatialtools Services Providers (a C shared library and a Python module)
based on the :doc:`GEOS <geos_overview>` and :doc:`OGR <gdal_overview>` Libraries.

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.

*ZOO API* : A server-side JavaScript API able to call and chain the ZOO
Services, which makes the development and chaining processes easier. 

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.

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
and JavaScript.
