First release of the LOD2 Stack

The welcome page from the LOD2 demonstratorThe LOD2 consortium is happy to announce the first release of the LOD2 stack available at: http://stack.lod2.eu. The LOD2 stack is an integrated distribution of aligned tools which support the life-cycle of Linked Data from extraction, authoring/creation over enrichment, interlinking, fusing to visualization and maintenance. The stack comprises new and substantially extended existing tools from the LOD2 partners and third parties.

The LOD2 stack is organized as a Debian package repository making the tool stack easy to install on any Debian-based system (e.g. Ubuntu). A quick look at the stack and its components is available via the online demo at: http://demo.lod2.eu/lod2demo. For more thorough experimentation a virtual machine image (VMware or VirtualBox) with pre-installed LOD2 Stack can be downloaded from: http://stack.lod2.eu/VirtualMachines/. More details and the instructions on installing the LOD2 Stack from scratch are available in the HOWTO Start document. The first release of the LOD2 stack contains the following components (available as Debian packages):

  • LOD2 demonstrator, the root package (LOD2)
  • Virtuoso, RDF storage and data management platform (Openlink)
  • OntoWiki, semantic data wiki authoring tool (ULEI)
  • SigmaEE, multi-source exploration tool (DERI)
  • D2R, RDF wrapper for SQL databases (FUB)
  • Silk, interlinking engine (FUB)
  • ORE, ontology repair and enrichment toolkit (ULEI)

As online services were integrated into the LOD2 Stack: PoolParty (taxonomy manager by SWCG) and Spotlight (annotating texts w.r.t. DBpedia by FUB). The LOD2 Stack also makes use of dataset metadata repositories such as thedatahub.org and http://publicdata.eu. A selection of the datasets has been packaged and are available in the LOD2 stack repository.

The LOD2 stack is an open platform for Linked Data components. We are happy to welcome new components. Detailed instructions how to integrate your component into the LOD2 Stack as Debian package are available in the HOWTO Contribute. For assistance or any questions related to the LOD2-stack contact support-stack@lod2.eu. From now on we will regularly release improved and extended versions of the LOD2 Stack. Major releases are expected for Fall 2012 and 2013.
