DBpedia has served as a Unified Access Platform for the data in Wikipedia for over a decade. In fact, DBpedia hosted a knowledge graph even before Google coined the term. Currently, the community, the board, and the DBpedia Association are re-envisioning DBpedia’s strategy. A part of the strategy involves rethinking the incentives for linking data via the DBpedia Databus. Andrea Volpini and David Riccitelli from WordLift had a very interesting meeting with Dr. Sebastian Hellmann from the University of Leipzig, who sits on the board of DBpedia, on this topic.
According to Sebastian Hellmann, the DBpedia Databus is part of a larger strategy following the mission to provide “Global and Unified Access to knowledge”. Therefore, it is a decentralized data publication, integration, and subscription platform. The DBpedia has been publishing data regularly and has already achieved a high level of connectivity in the data network. Now, DBpedia Databus is being envisioned as a hub, where everybody uploads data. In the hub, useful operations like versioning, cleaning, transformation, mapping, linking, merging, hosting are done automatically and then again dispersed in a decentral network to the consumers and applications. The overarching intent is to incorporate two major innovations that will have an impact on the data economy, i.e., providing global access and incorporating knowledge graphs into the unified access.
The goal is to reach out to create an access platform not only for Wikipedia (DBpedia Core), but also Wikidata, and subsequently for all other knowledge graphs and databases that are available. The result will be a network of data sources that focus on the discovery of data and tackles the heterogeneity (or in Big Data terms, variety) of data.
