Morph

Morph-RDB (formerly called ODEMapster) is an RDB2RDF engine developed by the Ontology Engineering Group, that follows the R2RML specification (http://www.w3.org/TR/r2rml/).

Morph-RDB supports two operational modes: data upgrade (generating RDF instances from data in a relational database) and query translation (SPARQL to SQL). Morph-RDB employs various optimisation techniques in order to generate efficient SQL queries, such as self-join elimination and subquery elimination.

Morph-RDB has been tested with real queries from various Spanish/EU projects and has proven to work faster than other state-of-the-art tools available. At the moment, Morph-RDB works with MySQL, PostgreSQL, H2, CSV files and MonetDB.

User guides: For those who want to use this project on an user level, you can find a little guide to on the main branch wiki : https://github.com/oeg-upm/morph-rdb/wiki

If, on the other hand, you want to edit the project or at least work from an IDE such as Eclipse, we suggest you to follow this steps:

Download the source code.
Once unziped, you may notice that the imports doesn�t match the actual directories. In order to avoid changing all the imports or all the directories, import this way: Import -> Maven -> Existing Maven Project, and select as root the folder where you unziped the project (it may take a few minutes).
Now that it�s finally imported, you can run the file es.upm.fi.dia.oeg.morph.r2rml.rdb.engine.MorphRDBRunner.scala (in other to pass the arguments in Eclipse, right click, Run As -> Run Configuration -> Arguments, and remember to imput both the path to the .properties file and it�s full name).
In case the program doesn�t find the file log4j.properties, move it from “morph-examples” to “morph-r2rml-rdb”, thought this file isn�t essential.

Acknowledgement: Since January 2016, the development of morph-RDB has been supported by the Mobile Age project (http://www.mobile-age.eu/).
