Dataset: openaire-lod (development version)

OpenAIRE LOD was a service that exported data from the OpenAIRE information space in RDF format, using Linked Open Data principles. The data was exported to Zenodo, with the last dump dated at March 3, 2021. This dataset consists of the "result" subset of the OpenAIRE LOD graph, including scientific results such as publications.

Only records that were valid RDF and had the "dateofcollection" property were included here. They were then sorted by the date of collection in ascending order. The first 2 (out of 28) million records that were obtained in this way are a part of this dataset.

See also the project documentation and the used ontology.

This README is a snapshot of documentation for the latest development version of the dataset. Full documentation for all versions can be found on the website.
