Questions about SPDX License Metadata Lookup

Does an absent FSF flag mean not free?

No. It means the snapshot did not supply that field for the entry. The page preserves that distinction.

Can I paste an SPDX expression?

This page looks up individual identifiers and names. It does not parse combinations such as AND, OR or WITH.

Does a match identify my project’s license?

No. It identifies a list entry. Read your project’s actual terms and obtain suitable advice when deciding legal obligations.
