The Work Object

Work objects represent the papers we ingest from preprint servers and publishers. Each object captures the stable metadata for a paper (title, identifiers, access information, and every version we’ve recorded) so you can rely on the shape staying the same across the API.

Each work has a stable public_id. As new versions of preprints are released and ingested by Drylab, they become part of the Work they belong to.

This is the standard structure of the core Work Object:

THE WORK OBJECT

   "public_id":"7334329443",

   "abstract":"This is an example abstract of the research paper...",
