LOD2 Creating Knowledge out of Interlinked Data

The LOD2 consortium proudly announces the release 1.1 of the LOD2 Technology Stack available at: http://stack.lod2.eu. The LOD2EU-funded (FP7) research project aiming to take the Web of Linked Data to the next level. Main research challenges: improve coherence and quality of data published on the Web, close the performance gap between relational and RDF data management, establish trust on the Linked Data Web and ... stack is an integrated distribution of aligned tools which support the life-cycle of Linked (Open) Data from extraction, authoring/creation over enrichment, interlinking, fusing to visualization and maintenance. The stack comprises 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 a more thorough experimentation, virtual machine images with LOD2 Stack installation script can be downloaded. More details and the instructions on installing the LOD2 Stack from scratch are available in the HOWTO Start section on the brand new LOD2 stack documentation wiki. The documentation wiki contains also  an overview of the webinars on the LOD2 stack and short use-case tutorials using the LOD2 stack. The IPR report describing the legal aspects of the LOD2 stack can also be found at this site.

This release contains updates to the components OntowikiSemantic Wiki providing support for agile, distributed knowledge engineering scenarios. OntoWiki facilitates the visual presentation of a knowledge base as an information map, with different views on instance data. It enables intuitive authoring of semantic content, with an inline editing mode ..., SilkThe Silk framework is a tool for discovering relationships between data items within different Linked Data sources. Data publishers can use Silk to set RDF links from their data sources to other data sources on the Web. (, and Virtuoso.
