# Introduction

OpenECOMP AAI-Common is a collection of common utility modules used by the other OpenECOMP AAI components (AAI-Resources and AAI-Traversal). These utilities include aai-schema, which contains the schema oxm and xsd files; aai-annotations, which enables the annotations on the schema files; and aai-core, which includes various java packages used by all AAI microservices. AAI-Resources and AAI-Traversal are already configured to pull these dependencies using maven. For more information on AAI-Resources and AAI-Traversal, please see the readme.md files in their respective repositories. This readme only covers AAI-Common.

# Compiling AAI-Common

Each module of AAI-Common can be compiled easily with a `mvn clean install -DskipTests`. To compile all of them at once, run this command at the top level of aai-common; to do so for a specific module, run it in that module's subdirectory. Integration tests are started by omitting the skipTests flag `mvn clean install`. Again, this can be done for all the submodules at once or for any one individually. 

# Logging

EELF framework is used for **specific logs** (audit, metric and error logs). They are tracking inter component logs (request and response) and allow to follow a complete flow through the AAI subsystem

Each microservice (AAI-Resources and AAI-Traversal) keeps its own logging directories. Please see their specific readmes for more information.

# Testing AAI-Common Functionalities
There are JUnit tests for aai-core and aai-annotations. Changes to the schema must be tested in the context of the AAI-Resources microservice via the REST interface. Please see the AAI-Resources readme for details on how to test via the REST API.
