About this package

Data model description engine: models and relations only

keel

Data model description engine. Business code defines resources, fields, and relations only. Control fields and control capabilities stay inside the engine. HTTP and store adaptors project the engine surface — they are not a business authoring API.

Canonical source: PerishLab/keel.

Cold start

use keel::adapt::db::Sqlite;
use keel::atom::string;
use keel::resource;
use keel::{Graph, bind};

#[resource]
struct Course {
    #[field(string)]
    code: string,
    #[field(string)]
    title: string,
}

#[resource]
struct Student {
    #[field(string)]
    no: string,
    #[field(string)]
    name: string,
    #[relation(Course, many2many)]
    courses: Course,
}

fn main() {
    let mut graph = Graph::new();
    graph.plug::<Course>().plug::<Student>();
    let core = bind(graph, Sqlite::memory()).expect("bind");
    let _id = core
        .put("Student", &[("no", "S01"), ("name", "ada")])
        .expect("put");
}

Engine face (Core)

Method Meaning
put / set / live / end insert, partial update, live list, soft-end
query / ask text → AST → run; ask takes Tree directly
AST from + where + link + order/page → always pack
tie / ties / cut many2many write on Core; read via link bond bags (H0)
edge law flat pack; root-only order/page — docs/edge.md
serve / listen axum (http feature)

HTTP surface

Native REST per resource (no association queries):

Method Path Engine
GET {prefix}/health liveness
GET {prefix}/{unit} live
GET {prefix}/{unit}/{id} one live row by id
POST {prefix}/{unit} put
PATCH {prefix}/{unit}/{id} set (partial body)
DELETE {prefix}/{unit}/{id} end
POST {prefix}/{unit}/{id}/{bond} tie body {"right": id}
DELETE {prefix}/{unit}/{id}/{bond}/{tie} cut
POST {prefix}/query body {"q":…} → always pack

listen.prefix in keel.toml is the api prefix (default empty).

Runtime config (keel.toml)

Repo-rooted, negentropy-style. Missing file uses the same defaults:

[listen]
host = "127.0.0.1"
port = 3000
prefix = ""
# prefix = "/api"

[store]
kind = "memory"
# kind = "file"
# path = ".local/keel.sqlite"

[cache]
kind = "memory"
# kind = "none"

let cfg = keel::config::load(".");
let store = cfg.open()?;
let core = bind(graph, store)?;
// listen(core.share(), &cfg.listen.host, cfg.listen.port).await?;

keel-api [ROOT] loads ROOT/keel.toml (default ROOT=.). CLI does not re-express policy keys — change the file.

Local process (sidecar)

# requires sidecar CLI installed
sidecar start --config sidecar.toml
# health: http://127.0.0.1:3000/health
sidecar stop --config sidecar.toml

keel-api is a demo binary (Student/Course selection + store/listen from keel.toml). forge is the staged scenario binary (docs/spec.md); keel-gate ships the default credential package (gate!(Actor) + wall).

Operating

runseal :init
runseal :guard    # unit tests + smoke + course + forge scenarios
runseal :smoke    # thin L2
runseal :course   # classic enroll/drop/schedule L2
runseal :forge    # forge slice act 1: data completeness L2
cargo run -p keel-api --locked

Scenario notes: docs/scenario.md.

Cold-start verification boundary: docs/verify.md.
