Deprecated. Concepts are superseded by [Topics](/data/topics/), OpenAlex's current subject-classification system. The concepts endpoints and the [`concepts`](/data/works/attributes/#concepts) field on works still work, but concepts are frozen — no longer recomputed or expanded — so new works are not tagged with them and the concept tree is not maintained. Use [topics](/data/topics/) (and the [aboutness](/data/aboutness/) hierarchy of [domains](/data/domains/), [fields](/data/fields/), and [subfields](/data/subfields/)) for anything new. This page is kept for the many links and workflows that still point at it.
