Permanent identifiers.
Every Haitiana entity has a permanent identifier, a resolver address and a machine-readable representation. Public access requires no key.
Identifier format
A v2 identifier contains the hai prefix, a type letter, a hyphen, eight random characters and a check character. It is permanent, carries no bibliographic meaning and is never reused.

Resolution
The address https://haitiana.org/id/{identifiant} redirects to the entity page (303), or, when requested with Accept: application/ld+json, returns its JSON-LD description (schema.org). Previously published merged entities redirect (301) to their replacement; a withdrawn entity returns 410 when its publication history is established.
curl -H 'Accept: application/ld+json' https://haitiana.org/id/haiw-sfdkaehxa
Validation
Validation normalizes case and I/L/O substitutions. In v2 it also verifies the check character; U is invalid. A typing error never creates a permanent redirect.
