| 1 | Welcome to the ZOO Project |

| 2 | ========================== |

| 4 | ZOO is a WPS (Web Processing Service) open source project released under a :ref:`MIT/X-11 style license <license>`. |
|---|
| 5 | It provides an OGC WPS compliant developer-friendly framework to create and chain WPS Web services. |
|---|
| 6 | ZOO is made of three parts: |
|---|
| 7 | |
|---|
| 8 | - ZOO Kernel : A powerful server-side C Kernel which makes it possible to manage and chain |
|---|
| 9 | Web services coded in different programming languages. |
|---|
| 10 | - ZOO Services : A growing suite of example Web services based on various Open Source libraries. |
|---|
| 11 | (get inspired !) |
|---|
| 12 | - ZOO API : A server-side JavaScript API able to call and chain the ZOO Services, which makes the |
|---|
| 13 | development and chaining processes easier. |
|---|
| 14 | |
|---|
| 15 | Powerful ZOO Kernel, that makes coffee |
|---|
| 16 | -------------------------------------- |
|---|
| 17 | |
|---|
| 18 | ZOO is based on a 'WPS Service Kernel' which constitutes the ZOO's core system (aka ZOO Kernel). |
|---|
| 19 | The latter is able to load dynamic libraries and to handle them as on-demand Web services. |
|---|
| 20 | The ZOO Kernel is written in C language, but supports several common programming languages in |
|---|
| 21 | order to connect to numerous libraries and above all to simplify the Web service end-developer's job. |
|---|
| 22 | |
|---|
| 23 | Use the ZOO Services and make your own |
|---|
| 24 | -------------------------------------- |
|---|
| 25 | |
|---|
| 26 | A ZOO service is a link composed of a metadata file (.zcfg) and the code for the corresponding |
|---|
| 27 | implementation. The metadata file describes all the available functions which can be called using |
|---|
| 28 | a WPS Exec Request, as well as the desired input/output. Services contain the algorithms and functions, |
|---|
| 29 | and can now be implemented in C/C++, Fortran, Java, Python, PHP, Perl and JavaScript. |
|---|
| 30 | |
|---|
| 31 | Easy implementation with the ZOO API |
|---|
| 32 | ------------------------------------ |
|---|
| 33 | |
|---|
| 34 | The ZOO API is a simple and concise JavaScript library designed to call and chain the ZOO Services |
|---|
| 35 | easily, and adds the capability to define logic in the chaining of your ZOO Services. |
