Open data contributions welcomed at European Data Forum 2014

without comments

The value of open data is increasing as more data is being released under an open license allowing anyone to freely use, reuse and redistribute it. This provides numerous opportunities for businesses and other organisations alike, and open data is becoming one of the pillars of Europe’s data economy. Open data is therefore one of the key themes at the European Data Forum 2014, which will take place 19-20 March 2014 in Athens, Greece.

We invite you to submit your contributions now and are specifically interested in innovative applications of open data. The call for Contributions is open until 10 Dec 22:00 CET.

Open data is increasingly becoming an integral part of governments’ agendas. In June, the G8 launched an Open data charter, committing to the ‘open by default’ principle. The European Commission released a document demonstrating how on the Commission implements this charter. Notable initiatives are the European Commission’s own open data portal and the portal publicdata.eu which aggregates data from governments’ open data portals throughout Europe. National open data portals are becoming more and more commonplace with notable examples such as the re-launched Swedish national open data portal oppnadata.se and the German national portal govdata.de.

The value that open data can bring is demonstrated in various ways. Publication of budget and spending data makes governments more transparent and allows citizens and journalists to hold their governments to account. Projects like OpenSpending are helping turn the data into meaningful visualisations and stories so that people can make sense of the data. Economic opportunities for the data are being explored by companies such as Open Corporates and start-up companies such as Nostalgeo, who make innovative use of open mapping data to integrate images of old post cards with modern maps.

We invite you to submit your contribution today. There is also a Call for Exhibition (CfE) in place and and we are offering interesting sponsoring bundles for organisations, projects and enterprises. We look forward to your submission!

Expanding publicdata.eu towards a more pan-European portal

without comments

I was cordially invited to attend a meeting of the Public Sector Information sub-Group on the pan-European Open Data portal to present our work on publicdata.eu, the prototype of a pan-European open data portal that we are developing as part of LOD2 project.

This was an excellent opportunity to talk with representatives of 19 EU across Europe that were at the meeting. It was great to see that many countries already have an open data portal or have just set one up, ranging from countries like Germany and France, to Austria and Slovakia. Some of these are already integrated in the pan-European publicdata.eu, but we also found out about portals that we were not aware of. My presentation focused on some of the key areas we are working on at the Open Knowledge Foundation.

Integrate more portals into publicdata.eu

As more official open data portals are being built, we are working to integrate those into publicdata.eu. It was interesting to see that countries are increasingly publishing their government data under open licenses, and that many were keen to have their data integrated in the pan-European portal that we are prototyping.

Increase use of the data

As part of the Apps for Europe project we are working with initiatives that stimulate innovative use of the data, such as via organising hackathons or app competitions. The goal of that project is to connect promising application developers to potential investors, and ensure that the data that is being published will be used successfully.

Work on standards for open data portals

The European Commission has funded the Open Data Support project to improve the visibility and facilitate the access to datasets published in open data portals. They initiated the working group that aims to develop a DCAT application profile for data portals in Europe. This will enable cross-data portal search for data sets and make public sector data better searchable across borders and sectors, in particular for data portals that are not based on the CKAN software that we develop and which runs publicdata.eu.

It was a very fruitful day in Luxembourg and I returned with additional homework to further expand publicdata.eu with new open data portals from across Europe. Watch this space!

European Data Forum 2013

without comments

Screen Shot 2013-01-22 at 3.57.15 PM                   A truly European Big Data community is on the rise



Press information 22.01.2013 for immediate release

The European Data Forum (EDF) is an annual meeting place for industry, researchers, policy makers, and community initiatives to discuss the challenges and opportunities of (Big) Data in Europe.

The next edition of the EDF will be held in Dublin, Ireland on April 9-10, 2013. The program will consist of presentations and networking sessions by industry leaders, academics, policy makers, and community organisers on a diverse range of topics, including research and technology development, training and knowledge transfer, and commercialization.

Vice-President of the European Commission Antonio Tajani recently launched the European Entrepreneurship Action Plan, which designates access to Open Data and Big Data as a must, stating that “investing in digital technologies is no longer a choice.” After the commitments of EC commissioner Neelie Kroess (for example, with Open Data) and others, this is again a clear “Go” signal for the European Data Economy.

This emerging community will enable promising ideas to move from the posing research questions stage to the successful acquisition and deployment of capital; at the same time, the community’s stakeholders will mutually reinforce commercial strategies that require a forward-looking, dynamic, and well-integrated EU-wide industry.

As the sector works to build in its own successes, it has to answer several strategic questions:

  • Is the European economy ready for Big Data?

What are the novel innovation and business models for Open and Linked Data? What platforms, marketplaces, policies, and strategies for the development of data ecosystems should be targeted?

  • Are we reaching out to relevant stakeholders?

Do the application scenarios and specific technical and non-technical concepts of Big Data providers and consumers meet demands for themes like Smart Cities, Environmental Research, Geo-Spatial Information, eScience, and Social Media?

  • What does Europe provide in terms of innovative Business Intelligence solutions?

How can the sector best align with European research agendas and roadmaps for science, technology and innovation, in particular in relation to research framework programmes such as Horizon 2020? Which framework conditions are essential for meeting Europe’s ambitions towards a profitable data economy, such as forthcoming standardisation needs and commercialisation opportunities?

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/.

The Open Data Challenge – organising Europe’s biggest open data competition

without comments

Over a year on from the Open Data Challenge many people still ask us about how we organised the competition. Hence we’ve put together a brief slide deck which takes a brief look behind the scenes as to how we organised it. It includes some advice for others planning similar initiatives.

As far as we know it is still Europe’s biggest open data competition to date – though we look forward to seeing even bigger and even better initiatives encouraging people to use public data for the public good in the future!

If you’re interested in talking to other organisers of open data competitions, you can join the open-government mailing list or our new appsforx mailing list.

Hosting LOD2 in Cambridge

without comments

The CKAN-powered data portal at publicdata.eu aggregates information on data from about 20 data portals across Europe. It’s part of the EU-funded LOD2 project on Linked Open Data, which held its regular plenary meeting over three days last week – hosted in Cambridge by the Open Knowledge Foundation. This meeting marked LOD2’s half-way point, two years through its four-year duration.

The last plenary was in Vienna in March – my write up here has much more information about the project. By a happy coincidence our meeting this time co-incided in Cambridge with a conference organised by Opening Up, another EU open data project, and we were able to link up with them at their event.

A taste of Cambridge

As host, my main concern this time was with the organisation of the event, which happily ran without a hitch. Meetings were held in style in the fine surroundings of Newnham College, with conference accommodation at another nearby college. Our visitors (from France, Germany, Austria, Poland, Serbia, and beyond) thus had a taste of the Cambridge experience, enhanced with dinner in a good local pub and a lunchtime punt trip on the River Cam. For additional authenticity, there were a couple of quick downpours while we were out on the river. Luckily they didn’t last long enough to spoil anyone’s fun.

The power of the coffee break

After the breakout sessions for each of the project’s ‘work packages’ I ran two very short ‘Open Space Technology’ sessions on Friday. OST emerged out of the observation that conference-goers often find the most productive part is the coffee breaks – where they can discuss and sort out the problems on their mind at the time. Despite its overly grand name, I’m a great fan of OST as a way of quickly setting up workshops and discussions on the ‘hot’ topics of the moment. Though we had time for what was barely a taster of OST, several productive conversations ensued that would perhaps have ‘fallen between the gaps’ of the individual work packages.

One topic emerged as particularly hot – that of usability. LOD2 is primarily a research project so the focus in the first two years has been mainly on results. It’s interesting and encouraging that so many partners are now keen to give attention to usability too, which is sure to help LOD2’s outputs survive after the project ends.

Neelie Kroes, EC Commissioner for the Digital Agenda mentions LOD2 project in OKFestival opening speech

without comments

Cross posted from the main LOD2 blog. Post written by Martin Kaltenböck of the Semantic Web Company.

Neelie Kroes, Vice President of the European Commission and Commissioner for the Digital Agenda in Europe gave this week an opening speech to the OKFestival 2012 in Helsinki, Finland – organised by the LOD2 partner Open Knowledge Foundation (OKFN).

Excerpt from the respective OKFN blog post: ‘Today Neelie gave a virtual address for participants at OKFestival, one of the largest open knowledge events to date. The event has convened over 800 open data, open content and open access advocates in Helsinki for six days of talks, workshops and hackathons. In her talk Neelie highlights the European Commission’s commitment to policies, projects and funding to support open data and open access, including for public sector information, cultural data, science and research. Her address closes with the following remarks: I know you at the OKFestival don’t need convincing about the benefits of openness, nor about the huge innovation that it can fuel. Rest assured, the EU is behind you.’



At the end of her speech she mentioned the LOD2 project as follows: ‘Fourth, we will of course continue to support research related to open data. Like the LOD2 project, using open source software to help people publish linked data.’

The LOD2 team is very happy about this reference!
