⭐ Core Definition: Linked data

In computing, linked data is structured data which is associated with ("linked" to) other data. Interlinking makes the data more useful through semantic queries. Tim Berners-Lee, director of the World Wide Web Consortium (W3C), coined the term in a 2006 design note about the Semantic Web project.Part of the vision of linked data is for the Internet to become a global database.

Linked data builds upon standard Web technologies such as HTTP, RDF and URIs, but rather than using them to serve web pages and hyperlinks only for human readers, it extends them to share information in a way that can be read automatically by computers (machine readable).Linked data may also be open data, in which case it is usually described as Linked Open Data.

👉 Linked data in the context of DBpedia

DBpedia (from "DB" for "database") is a project aiming to extract structured content from the information created in the Wikipedia project. This structured information is made available on the World Wide Web using OpenLink Virtuoso. DBpedia allows users to semantically query relationships and properties of Wikipedia resources, including links to other related datasets.

The project was heralded as "one of the more famous pieces" of the decentralized linked data effort by Tim Berners-Lee, the inventor of the World Wide Web. As of June 2021, DBpedia contained over 850 million semantic triples.

Linked data in the context of Data.europa.eu

The European Data Portal is a web portal providing open data published by EU Institutions, national portals of EU Member states and non-member states, as well as international organisations of predominantly European scope, launched on April 21, 2021. The portal consolidates datasets previously available via the EU Open Data Portal and the European Data Portal into a single meta-catalogue. The European Data Portal, launched in its beta version on November 16, 2015, was an initiative of the European Commission, and part of the Digital Single Market.

Currently, more than 1,600,000 datasets are published on the portal, originating from 178 catalogues. The portal is a metadata catalogue: in it, metadata from other data and geospatial data catalogues are published following a common ontology, namely the DCAT Application Profile for data portals in Europe (DCAT-AP) with the aim of fostering and facilitating re-use of open data, promotion and support for the publication of (meta)data of high quality and use of Linked Open Data.
