Callimachus LogoThe Callimachus Project has announced that the latest release of the Open Source version of Callimachus is available for immediate download.
Callimachus began as a linked data management system in 2009 and is an Open Source system for navigating, managing, visualizing and building applications on Linked Data.
Version 1.0 introduces several new features, including:
  • Built-in support for most types of Persistent URLs (PURLs), including Active PURLs.
  • Scripted HTTP content type conversions via XProc pipelines.
  • Ability to access remote Linked Data via SPARQL SERVICE keyword and XProc pipelines.
