The large size of the OpenAIRE Research Graph is a major impediment for beginners to familiarise with the underlying data model and explore its contents.
Working with the Graph in its full size typically requires access to a huge distributed computing infrastructure which cannot be easily accessible to everyone.
[The OpenAIRE Beginner’s Kit]( https://doi.org/10.5281/zenodo.7490192) aims to address this issue. It consists of two components:
* A subset of the Graph composed of the research products published between 2022-06-29 and 2022-12-29, all the entities connected to them and the respective relationships.
* A Zeppelin notebook that demonstrates how you can use PySpark to analyse the Graph and get answers to some interesting research questions. A guide to Apache Zeppelin can be found [here](https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.5/bk_zeppelin-component-guide/content/ch_overview.html).
