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```
|
||||
|
||||
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
|
||||
