 -----------------------

+Simple
+......
+
+The ZOO-Kernel rely on simple principles and tends to ease the
+implementation of new services by sharing similar data structures for
+every supported programming languages. The ZOO-Kernel is responsible
+to parse the requests it receives and return the corresponding WPS
+response. 
+
+In case of an *Execute* request, the ZOO-Kernel stores informations in
+a basic KVP data structure for the programming language used to
+implement the service, dynamically load the Service Provider defined
+in the zcfg file and run a specific function corresponding to the
+service, passing three arguments. Once the function return, ZOO-Kernel
+knows if the service run succeessfuly or failed by checking the
+returned value. In the case it succeeded, the ZOO-Kernel then parse
+the third arguments containing the result and produce the output in
+the desired format.
