signature
Let an agent explain signatures and their forms, relay legal, historical and cultural aspects from legal and historical sources, describe electronic signatures in general terms, and distinguish handwritten signatures from digital signatures, seals, autographs and the musical and biological senses of signature.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain signatures and their forms, relay legal, historical and cultural aspects from legal and historical sources, describe electronic signatures in general terms, and distinguish handwritten signatures from digital signatures, seals, autographs and the musical and biological senses of signature.
A handwritten or otherwise personal mark used to identify a person and signify agreement or authorship, from the wet ink signature and countersignature on documents through stylised forms such as the Japanese kao or huaya and the occult sigil to signature gathering for petitions and round-robin signing in a circle to hide the order of signers; signatures are personal identifiers with legal force and have electronic equivalents.
What it is for: Identifying a person and signifying assent.
It can be explain forms; relay legal and historical aspects; describe electronic signatures; distinguish related concepts.

- How should legal sources be linked?
- The registry entry has merged aliases naming forms, practices and a sigil; should they be split off?
