Endorsement vocabulary

OpenXiv endorsements are typed verbs, not generic likes. An endorser picks a specific verb that names what they actually did with the paper, and that verb is what shows up on the paper page, in the Trust Passport, and on AT-proto records. The full controlled vocabulary is below; each term has a stable URI so external tools can resolve it.

Set @id: https://openxiv.net/vocabulary#endorsement-verbs

Verified derivation verified-derivation

The endorser worked through the paper’s central derivation, step by step, and the algebra and assumptions hold. This is the strongest mathematical endorsement on OpenXiv.

Reproduced result reproduced-result

The endorser independently re-ran the experiment, simulation, or numerical pipeline described in the paper and obtained results consistent with the reported claims, within the stated tolerance.

Checked references checked-references

The endorser audited the bibliography: every cited source resolves, every quoted figure or claim attributed to a prior work matches what that prior work actually says, and there are no fabricated entries.

Useful background useful-background

The endorser found the paper a useful pedagogical or contextual reference, even if they did not verify every result. A lower-stakes signal than verification but more specific than a generic like.

Important but flawed important-but-flawed

The endorser thinks the paper raises a question worth engaging with but contains identifiable defects (methodological, derivational, or evidentiary). The endorsement is expected to cite the defect.

Needs correction needs-correction

The endorser has identified a concrete error and recommends the author publish a corrected version. The endorsement should name the specific section, equation, or claim that is wrong.
