 --------------------------
 This module defines a **collector worker application** that runs on Hadoop.
 
-It is responsible for harvesting metadata using different plugins.
+It is responsible for harvesting metadata using different collector plugins and transformation into the common metadata model.
 
-The collector worker uses a message queue to inform the progress 
+# Collector Plugins
-of the harvesting action (using a message queue for sending **ONGOING** messages) furthermore, 
-It gives, at the end of the job, some information about the status 
-of the collection i.e Number of records collected(using a message queue for sending **REPORT** messages).
-
-To work the collection worker need some parameter like:
-
-* **hdfsPath**: the path where storing the sequential file
-* **apidescriptor**: the JSON encoding of the API Descriptor
-* **namenode**: the Name Node URI
-* **userHDFS**: the user wich create the hdfs seq file
-* **rabbitUser**: the user to connect with RabbitMq for messaging
-* **rabbitPassWord**: the password to connect with RabbitMq for messaging
-* **rabbitHost**: the host of the RabbitMq server
-* **rabbitOngoingQueue**: the name of the ongoing queue
-* **rabbitReportQueue**: the name of the report queue
-* **workflowId**: the identifier of the dnet Workflow
-
