What this tool does not do / Limits

This checks against a built-in list of common identifiers only. It is not the full live SPDX list, and it does not give legal advice about licences.

Frequently asked questions

Is my identifier invalid if it is not found?

Not necessarily. It may simply be outside the built-in list of common identifiers used here.

Does this give legal advice?

No. It only checks whether the text matches an entry in the built-in list.
