Zenodo Open Metadata snapshot - Training dataset for records classifier building

This dataset contains Zenodo's published open access records' metadata, including also records that have been marked by the Zenodo staff as spam and deleted. The dataset is a gzipped compressed JSON-lines file, where each line is a JSON object representation of a Zenodo record. Each object contains the terms:<br> <strong>part_of, thesis, description, doi, meeting, imprint, references, recid, alternate_identifiers, resource_type, journal, related_identifiers, title, subjects, notes, creators, communities, access_right, keywords, contributors, publication_date</strong><br> <br> which are corresponding to the fields with the same name available in Zenodo's record JSON Schema at https://zenodo.org/schemas/records/record-v1.0.0.json. In addition, some terms have been altered:<br> <br> The term <strong>files</strong> contains a list of dictionaries containing <strong>filetype</strong>, <strong>size,</strong> and <strong>filename </strong>only.<br> The term <strong>license</strong> contains a short Zenodo ID of the license (e.g "cc-by").<br> The term <strong>spam</strong> contains a boolean value, determining whether a given record was marked as a spam record by Zenodo staff.<br> <br> Some values for the top-level terms, which were missing in the metadata may contain a <strong>null</strong> value. A smaller uncompressed random sample of 200 JSON lines is also included to allow for testing and getting familiar with the format without having to download the entire dataset.
