# Ranking Workflow for OpenAIRE Publications
This project contains the files for running a paper ranking workflow on the openaire graph using apache oozie.
All scripts are written in python and the project setup follows the typical oozie workflow structure:
- a workflow.xml file containing the workflow specification
- a job.properties file specifying parameter values for the parameters used by the workflow
- a set of python scripts used by the workflow
**NOTE**: the workflow depends on the external library of ranking scripts called [BiP! Ranker](https://github.com/athenarc/Bip-Ranker).
You can check out a specific tag/release of BIP! Ranker using maven, as described in the following section.
## Build and deploy
Use the following command for packaging:
```

mvn package -Poozie-package -Dworkflow.source.dir=eu/dnetlib/dhp/oa/graph/impact_indicators -DskipTests
```
Deploy and run:
```
mvn package -Poozie-package,deploy,run -Dworkflow.source.dir=eu/dnetlib/dhp/oa/graph/impact_indicators -DskipTests
