description: The OpenAIRE Graph is an Open Access dataset containing metadata about research products (literature, datasets, software, etc.) linked to other entities of the research ecosystem like organisations, project grants, and data sources. The large size of the OpenAIRE 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 aims to address this issue. It consists of two components: A subset of the OpenAIRE 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. The subset is composed of the following parts: <strong>publication.tar</strong>: metadata records about research literature (includes types of publications listed here) <strong>dataset.tar</strong>: metadata records about research data (includes the subtypes listed here) <strong>software.tar</strong>: metadata records about research software (includes the subtypes listed here) <strong>otherresearchproduct.tar</strong>: metadata records about research products that cannot be classified as research literature, data or software (includes types of products listed here) <strong>organization.tar</strong>: metadata records about organizations involved in the research life-cycle, such as universities, research organizations, funders. <strong>datasource.tar</strong>: metadata records about data sources whose content is available in the OpenAIRE Graph. They include institutional and thematic repositories, journals, aggregators, funders' databases. <strong>project.tar</strong>: metadata records about project grants. <strong>relation.tar</strong>: metadata records about relations between entities in the graph. <strong>communities_infrastructures.tar</strong>: metadata records about research communities and research infrastructures<br> <br> Each file is a tar archive containing gz files, each with one json per line. Each json is compliant to the schema available at http://doi.org/10.5281/zenodo.7492151. A Zeppelin notebook that demonstrates how you can use PySpark to analyse the Graph and get answers to some interesting research questions: <strong>beginners_kit_zeppelin_notebook.json</strong>. Here a guide to Apache Zeppelin. <br>
description: This is a subset of the OpenAIRE Graph that you can use to get familiar with the data model and test your code on a smaller dataset. For your data analysis tasks, you can use the full dump available at https://doi.org/10.5281/zenodo.3516917. For more information on the OpenAIRE Graph and its data model, see (https://graph.openaire.eu/docs/data-model/).
