Hello, I need a R2RML processor that can access PostgreSQL databases. So far I used Spyder accompanied with MySQL, but unfortunately it doesn't support PostgreSQL. I also used D2RQ but it has his own mapping language, its an option, but I would rather use R2RML if es possible. Thanks. |

The W3C RDB2RDF Implementation Report[1] presents a list of RDB2RDF tools that were used to pass the test cases. Some of these tools were tested on PostgreSQL. Disclaimer: I'm the developer of Ultrawrap [2], which implements the RDB2RDF standards. |

R2RML only just became a recommendation in September 2012. IMO there has not been enough time for a host of R2RML tool offerings as of yet (I'm hopeful for the future though :-). |
@ Jesus: how was ur experience with spyder? Im working on same topic but not selected any R2Rml processor yet. till now came to know about -ontop-.
@Isma. I have been testing Spyder with MySQL and it worked fine. I´m actually thinking about porting the PosrgreSQL database to MySQL in order to use Spyder.
PD. If you check the Spyder forum[1] I have left one Question that describes a basic example of mapping that might be useful.
