Protocols SPARQL Protocol, HTTP/REST, Native binary

Standalone server exposes /sparql (SPARQL 1.1 Protocol over HTTP) and /tql (an HTTP interface for its native TQL/iTQL query language); the underlying Mulgara driver also talks to remote servers via SOAP or RMI (RMI covered here as Native binary; SOAP has no exact match in the controlled vocabulary). Project has been dormant since around 2014.

License OSL-3.0

Corrects current value (Apache-2.0). The actual LICENCE.txt in the repo is the Open Software License v3.0, matching GitHub's own OSL-3.0 classification; the README's text (which says 'version 1.1') is stale copy left over from the Kowari era.

Released 2006

Confirms current value. Mulgara's own release notes explicitly label v1.0.0 the initial release of Mulgara, posted August 19, 2006, after forking from the Kowari project (whose own lineage traces back to a 2003 beta) over a trademark dispute with Northrop Grumman.

  • This is the initial release of Mulgara. The initial release is a fork from Kowari v1.1, as of August 1, 2005.

Language Java

Confirms current value. The repo is 95.5% Java by GitHub's byte count, and the project's own install guide has readers install a JDK and run the server as a Java jar.
