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.

@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.

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 :-).

You could give this a try: https://github.com/nkons/r2rml-parser It works well with postgres.

Thanks, I will check it out. Personally I won't recommend Spyder anymore, the forum doesnt't exist anymore and neither do the support aptitude. They are now focusing on different projects.
