LOD2: Creating Knowledge out of Interlinked Data

The lighthouse project LOD2 was crucial for the adoption of Linked Data technologies in an enterprise context. For four years, 15 key players of this technology field were joining forces to develop new methods and technologies and make their complementary software solutions available as an integrated technology stack. Through the cooperation with industry partners, the technologies were directly applied and further developed.

“ Between 2007- 2013 the European Union’s F7 Research & Innovation program funded projects worth more than 8 billion Euro. An official evaluation of the funded projects showed that LOD2 is among the three best projects that successfully achieved sustainable innovation transfer to the industry.”

What Is Included in the Linked Data Technology Stack?

The Linked Data Technology stack includes software tools and components that cover the whole Linked Data Lifecycle from data storing, integration, linking to publishing, analysing and  data visualisation. The separate Linked Data solutions were made compatible. Performance gaps as compared to relational data bases were substantially improved. Companies have a complete solution portfolio at their disposal to build and adopt Linked Data architectures and applications.

How Is the Linked Data Technology Stack Applied?

During the project more than 25 companies benefited from consulting services around the Linked Data Technology stack. The implementation of the technologies with industry partners were a crucial part of the project. The global publisher Wolters Kluwer started to build a completely new data-driven business model based on these technologies. It transformed its highly specialised data resources around the legal and tax sector into a machine-readable format and started its shift from a document-oriented publisher towards an entity-centric data broker. Also new licensing models to monetise the Linked (Open) Data were established. Government organisations from Serbia and Poland as well as the European Commission made their publicly available statistical data sets Linked Data standards-conform, which make them reusable in various scenarios.

Further Developments at Semantic Web Company

The PoolParty data transformation component UnifiedViews was build and highly developed through this project, which was key to make the Linked Data Lifecycle fully operable and enterprise-ready. Through the large-scale integration efforts with third-party vendors, PoolParty Semantic Suite improved its REST APIs. The product also benefited from general methodological improvements around Semantic Web technologies, which makes the W3C standards even more interoperable.
