Description of the Module
--------------------------
This module defines a **collector worker application** that runs on Hadoop.
This module defines a set of oozie workflows for the **collection** and **transformation** of metadata records.
Both workflows interact with the Metadata Store Manager (MdSM) to handle the logical transactions required to ensure
the consistency of the read/write operations on the data as the MdSM in fact keeps track of the logical-physical mapping
of each MDStore.
It is responsible for harvesting metadata using different plugins.
## Metadata collection
The collector worker uses a message queue to inform the progress
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).
The **metadata collection workflow** is responsible for harvesting metadata records from different protocols and responding to
different formats and to store them as on HDFS so that they can be further processed.
To work the collection worker need some parameter like:
### Collector Plugins
* **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
Different protocols are managed by dedicated Collector plugins, i.e. java programs implementing a defined interface:
##Plugins
* OAI Plugin
```eu.dnetlib.dhp.collection.plugin.CollectorPlugin```
## Usage
The list of the supported plugins:
* OAI Plugin: collects from OAI-PMH compatible endpoints
* MDStore plugin: collects from a given D-Net MetadataStore, (identified by moogodb URI, dbName, MDStoreID)
* MDStore dump plugin: collects from an MDStore dump stored on the HDFS location indicated by the `path` parameter
# Transformation Plugins
