Metanome

Build Status Coverage Status

The Metanome project is a joint project between the Hasso-Plattner-Institut (HPI) and the Qatar Computing Reserach Institute (QCRI). Metanome provides a fresh view on data profiling by developing and integrating efficient algorithms into a common tool, expanding on the functionality of data profiling, and addressing performance and scalabilities issues for Big Data. A vision of the project appears in SIGMOD Record: "Data Profiling Revisited".

The Metanome tool is supplied under Apache License. You can use and extend the tool to develop your own profiling algorithms. The profiling algorithms contained in our downloadable Metanome build have HPI copyright. You are free to use and distribute them for research purposes.

Building Metanome

Metanome is a maven project, which can be build by executing:

mvn verify

The verify phase should be executed as GWTTests are executed in this phase of the build.

Metanome can be packaged together with a jetty webserver and profiling algorithms. To speedup builds this package is not created in the default maven profile. The deployment package can be created by executing the build with the deployment profile:

mvn verify -P deployment

or by executing package on the deployment project directly (if metanome has not been installed dependencies will be retrieved online):

mvn -f deployment/pom.xml package

Downloads

Metanome releases can be found on the download page at:

Documentation

The Metanome tool, information for algorithm developers and contributors to the project can be found in the github wiki.

Javadocs for the project can be found at https://hpi.de/naumann/sites/metanome/javadoc.
