Get Tupelo (22)

Build with Maven

Tupelo 2 is designed to be built with Maven, although it can also be built in Eclipse.

After checking out Tupelo 2, make sure Maven is installed and configured, change to the top-level directory, and issue the following command:

mvn install

Note that building Tupelo for the first time will require an active internet connection, so Maven can download its plugins, as well as the libraries Tupelo depends on.

If you have any other problems building, email futrelle (at) ncsa.uiuc.edu.

Download Tupelo

Tupelo is available as a download, although we recommend checking it out of SVN instead.

You can download Tupelo here.

Tupelo 2.5 release notes

Tupelo 2.5 contains several important new features:

  • Unifier (i.e., SPARQL select) now provides ordering and paging parameters which are implemented for a wide variety of Contexts, including ones that don't natively support SPARQL
  • Java-to-RDF mapping has been enhanced with performance improvements and many convenience methods.
  • Operator dispatch is now entirely dynamic, allowing the Tupelo kernel to apply dispatching policies (such as future security enhancements) globally rather than only for cooperating Context implementations
