Notes

attachments references documents that are included as additional files in the .sdf archive under the vendor/ prefix or as part of the visual.pdf compound document.
Government authorities will specify the exact schema.json required for permit applications. The schema enforces mandatory fields specific to the permit type and jurisdiction.
Digital signatures are strongly recommended for permit applications — use sdf sign after validation.

Validating and signing

sdf validate permit_application.sdf
sdf sign permit_application.sdf --key-id production-key
sdf verify permit_application.sdf
