European Flagship Project for Linked Open Data releases an new toolset to exploit the potential of data

without comments

Official Press release from 7.12.2012:

We are living in a time of an emerging new data economy: the amount of data is growing rapidly and the need for more efficient data management is rising to really exploit the potential of data. Linked Open Data (LOD) principles and technologies provide powerful ways of data publishing, consumption and integration for publishers, enterprises and governmental institutions. The EU funded project LOD2 – creating knowledge out of interlinked data – offers a freely available bundle of services and technologies targeted at the rapidly growing Web of Data!

 The LOD2 project consortium (http://lod2.eu) is excited to announce a bundle of services and activities in the field of Linked Open data (LOD) as well as the 2nd release of the LOD2 technology stack available at: http://stack.lod2.eu.

 The project coordinator Dr. Sören Auer states that “in a world of an emerging new data economy innovative and scalable mechanisms and technologies are needed to solve the arising data management problems – we see that lots of organisations are seeking for state-of-the-art data publishing and integration technologies along the whole data value chain to be able to efficiently use this growing amount of data. The efficient handling of data – available inside of organisations as well as on the internet – becomes more and more important to reach competitive advantage.”

In December 2012 the 2nd release of the LOD2 Technology Stack has been launched. This marks a major outcome of the 4-year EU-funded LOD2 project after the second project year. This technology stack is an integrated distribution of aligned tools supporting the life-cycle of Linked Data from extraction, authoring, over enrichment, interlinking, fusing to visualization. The stack comprises new and substantially extended tools from LOD2 members and 3rd parties.

 Vital to alleviate the data and information overload, Linked Data technologies and services are providing the foundation for the future web of data. Their continuous development by LOD2 members from the early emergence of Linked Data as a paradigm for integrating and publishing structured data on the Web and the 2nd release of the new LOD2 Stack, make it easier and more efficient for professionals from across government and industry to publish and consume linked data on the Web as well as inside their organisations.

All information about the LOD2 Technology Stack is available on: http://stack.lod2.eu.

Details about the 2nd release of the LOD2 Stack

The LOD2 consortium proudly announces release 2.0 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 tools from the LOD2 partners and third parties.

More details and instructions on installing the LOD2 Stack locally are available in the HOWTOSTART document: http://bit.ly/lod2-stack-how-to. 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 on this site.

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. For a more thorough experimentation a virtual machine images with LOD2 Stack installation script can be downloaded from http://stack.lod2.eu/VirtualMachines.

This second release of the LOD2 Technology Stack contains updates to the components Ontowiki, Silk, SigmaEE and Virtuoso.

The LOD2 Technology Stack has the following new components since release 1.1:

  • The assisting SPARQL editor SPARQLED (DERI),

  • The LOD enabled Open Refine (previously Google Refine) (ZEMANTA),

  • The extended version of SILK (University of Mannheim / previous FUB) with link suggestion management from LATC (DERI),

  • The rdfAuthor library which allows to manage structured information from RDFa-enhanced websites (ULEI),

  • the SPARQLPROXY which is a PHP based forward proxy for remote access to SPARQL endpoints (ULEI)

Release 2.0 contains also a first contributed Debian package for a component which is maintained by a group outside the LOD2 consortium. With the help of ULEI a package for the STANBOL engine (http://stanbol.apache.org/) has been contributed.

From now on we will regularly release improved and extended versions of the LOD2 Stack. The next intermediate release is to be expected in spring 2013.

The existing and new components are now accessible via the LOD2 demonstrator webinterface: http://demo.lod2.eu/.

LOD2 freely available Webinar series on Linked Open Data tools and services

The LOD2 Webinar series offers monthly free Webinars about Linked Open Data tools and services based around the LOD2 project, the LOD2 Stack and the Linked Open Data Life Cycle, also in the form of 3rd party tools and services.

In total 11 recorded Webinar tutorials are available so far that cover mainly Linked Open Data software tools like the linking framework SILK, the semantic wiki Ontowiki, the triple store server Virtuoso or the PoolParty Semantic Information management Suite. Also service tutorials like ‘Linked Data Management’ can be found in the webinar repository available on the LOD2 website: http://lod2.eu/BlogPost/webinar-series.

The next upcoming webinar is on the 2nd release of the LOD2 Technology Stack:

What:The 2nd release of the LOD2 Stack Presenter: Tenforce, Belgium When: December 12, 2012, 04.00pm CET Info & registration: http://bit.ly/lod2-webinar-dec2012

Followed by free webinars by Zemanta in January13, University of Mannheim about Spotlight in February and by the Open Knowledge Foundation (OKFN) about publicdata.eu and CKAN in March 2013.

If you are interested in Linked (Open) Data principles and mechanisms, LOD tools & services and concrete use cases that can be realised using LOD then join us in the free LOD2 webinar series!
