Based loosely on the ORM (Object to Relational Mapping) family of software, Topaz is a powerful object to triple persistence and query service. It has its own software codebase (http://gandalf.topazproject.org) and integrates with both the Fedora Repository service and the Mulgara RDF Database (semantic triple-store). Major re-usable software components of Topaz include the OTM - Object Triple Mapping and OQL - Object Query Language. The Topaz Project is working with the Fedora Repository Project on re-architecture efforts that benefit both projects and bring them closer together. One result of this work in the past 6 months is the new Akubra Project.
