Posters.science Poster Corpus 1: CC0 Licensed

POSTERS.SCIENCE POSTER CORPUS 1: CC0 LICENSED A bulk release of poster metadata from Posters.science (https://posters.science), a platform that makes scientific research posters Findable, Accessible, Interoperable and Reusable (FAIR) by extracting structured, standards-aligned metadata from deposited poster PDFs. The full corpus is released as five separate deposits, split by license, so that each deposit carries a license everything inside it can legitimately be shared under. This is Corpus 1 of 5. - Released under: CC0 1.0 Universal (CC0-1.0) - Records: 1,599 - Format: records.ndjson, one JSON record per line - Export date: 2026-08-13 WHAT IS IN THIS CORPUS This corpus contains two kinds of poster records: posters licensed under CC0 and posters under a more restricted license for which we used only the repository-provided metadata (which itself is CC0). More details are available at https://docs.posters.science/docs/bulk-corpus.html. FILE FORMAT records.ndjson holds one JSON object per line. posterJson follows the Poster Schema we have established based on the DataCite Metadata schema and the InvenioRDM schema. Each line is a wrapper around one poster record. posterJson holds the record itself; the surrounding fields id, posterUrl, imageUrl, publishedAt, license and metadataOnly are added by this export and are not part of the Poster Schema. metadataOnly states which kind of record it is: false means the record carries poster extracted metadata, true means repository metadata only. imageUrl is present only where a thumbnail exists. More details are available at https://docs.posters.science/docs/schema.html, and the schema itself is published at https://github.com/fairdataihub/poster-json-schema. THE FIVE CORPORA The DOIs for all five corpora are listed on the documentation site at https://docs.posters.science/docs/bulk-corpus.html.
