Rust schemas

acorn-schema contains ACORN’s portable data model, validation rules, persistent identifiers, and metadata-standard types. It does not require ACORN’s host filesystem, process, database, or network services.

Installation

Add the crate to a Rust project:

cargo add acorn-schema

Schema and validation functions can then be used directly:

#![allow(unused)]
fn main() {
use acorn_schema::validation::rules::{ark, arxiv, doi, isni, orcid, ror};

assert!(ark("ark:/1234/w5678").is_ok());
assert!(arxiv("arXiv:2106.09685").is_ok());
assert!(doi("10.11578/dc.20250604.1").is_ok());
assert!(isni("https://isni.org/isni/0000000492299539").is_ok());
assert!(orcid("https://orcid.org/0000-0002-2057-9115").is_ok());
assert!(ror("01qz5mb56").is_ok());
}

See the acorn-schema API documentation for the complete public surface and Persistent identifier lifecycle for identifier behavior.

The alloc-capable acorn_schema::standard::zon module encodes and decodes the JSON data model without host I/O or an additional runtime dependency. See ZON serialization for the supported profile and file conventions.

The portable acorn_schema::standard::dublin_core module models the current DCMI terms, legacy element namespace, DCMI type vocabulary, and DCAM terms as a normalized RDF graph. Its local codecs cover native graph JSON and YAML, JSON-LD, RDF/XML, and Turtle. See Dublin Core for the data model, safety boundaries, and crosswalk behavior.

Local PID validation checks parsed structure and, for ISBNs, ISNIs, ORCIDs, and RORs, the implemented check digit. It does not confirm registration with an external authority.
