Linked Data for “Open Education”/Learning?

Stefan Dietze

1. Linked Data for data sharing, enrichment and interpretation

LD stack (RDF, SPARQL, deref. URIs) to improve interoperability of learning/user data

facilitate vision of Open Education & OER across isolated platforms

2. Linked Data as body of knowledge for learning & education

Vast amount of publicly available resources and (meta)data

Dedicated OER and university data + „knowledge resources“ (from DBpedia to Slideshare)

LinkedUp Challenge to identify innovative tools & applications

Evaluation methods and approaches

“LinkedUp” – Linking Web Data (for Education) L

Data curation & profiling

Technology transfer & community-building

Collecting & exposing open data of educational relevance => LinkedUp Data Catalog

Profiling and linking of Web Data => LOD dataset profiles

Disseminating knowledge & building communities (educators, computer scientists, data engineers)

Gathering stakeholder feedback: use cases, and requirements

European project aimed at advancing take-up of open data and related technologies
