You can download the full OpenAIRE Graph dataset, sub-graph datasets, and other related datasets along with their schemas in Zenodo. Access the Graph documentation for all resources related to downloading these materials, including how to cite them. It should however be noted that these files are of substantial size and therefore not easy to load on a local machine.
If you would like to download some parts locally, access our Beginner's Kit which can also help to familiarise yourself with the underlying data model and explore its contents. This dataset includes a subset of the Graph, which is easier to handle in a local machine (e.g., a laptop), and a notebook with indicative queries for demonstration purposes.
