In September 2005, Tucana was bought by Northrop Grumman. In January 2006, Northrop Grumman threatened a Kowari developer with legal action if he released any new version of Kowari. As a consequence, Kowari was forked in July 2006. It was renamed to Mulgara because Northrop Grumman owns the Kowari trademark. All development on Kowari has stopped and the community moved to Mulgara.
Mulgara is not based on a relational database due to the large numbers of table joins encountered by relational systems when dealing with metadata. Instead, Mulgara is a completely new database optimized for metadata management. Mulgara models hold metadata in the form of short subject-predicate-object statements, much like the W3C's Resource Description Framework (RDF) standard. Metadata may be imported into or exported from Mulgara in RDF or Notation 3 form.
