Upgrade to RDF4j #6

Closed barthanssens closed 6 years ago

barthanssens commented 8 years ago

Eclipse RDF4j is the new name / project for Sesame (note that RDF4j 2.0, which is equivalent to Sesame 4.1, requires Java 8). Upgrading would be nice, since the version used by RMLio is relatively old.

Idd, I have already upgraded to RDF4J 2.0, but still checking if everything is ok before push public.

To be honest though, I'm a bit concerned regarding Java 8 dependency.

barthanssens commented 8 years ago

In that case you could consider using RDF4j 1.0, which is the Java 7 backport of RDF4j 2.0.

The benefit would be that RMLio can stay a little longer on Java 7, while already using the new org.eclipse.rdf4j namespace (and e.g. IRI instead of URI), so this would smoothen the upgrade path a bit.

Any progress on this?

Just FYI:

Oracle has ended public support of Java 7 on April 2015 (https://java.com/en/download/faq/java_7.xml),
Red Hat ends support of OpenJDK 7 in June 2018.

RML-Mapper is just 2+ years old. Java 8 was released in March 2014. I'm not sure anyone may have a problem with RML-Mapper requiring Java 8.

Hi,

We've updated the RMLMapper and it can now be found here. In the new version we use RDF4J.
