Component Overview

Component entities are structured parts of a work that OpenAlex models in detail but doesn’t give their own OpenAlex IDs. They don’t stand alone: you never fetch one directly or filter a /component/ endpoint — they appear inside a work object, and you reach them by selecting the field that holds them.

They sit between native entities (which get minted IDs and are curatable) and vocabulary (fixed controlled lists). A component is real and richly structured, but it’s meaningful only in the context of its work.

The component entities

• Authorships — the join between a work and its authors: for each author, their raw name as printed, their position, whether they’re corresponding, and the institutions they listed. Lives in work.authorships.
• Locations — each place a version of the work is available (the publisher’s site, a repository, a preprint server), with its version, license, and open-access status. Lives in work.locations / primary_location / best_oa_location.
• Raw affiliation strings — the exact affiliation text an author printed on a work, before OpenAlex matches it to an institution. The raw input to institution disambiguation.

Because components carry much of a work’s richest metadata, their fields are documented on their own pages here rather than crammed into the works attribute dictionary.
